Unit reliability is dependent upon these considerations. Where your application varies from the guidelines presented, it should be reviewed with the local Trane sales engineer.Unit SizingIntentionally oversizing a unit to assure adequate capacity is not recommended. Erratic system operation and excessive compressor cycling are often a direct result of an oversized condensing unit. In addition, an oversized units usually more expensive to purchase, install and operate. If oversizing is desired, consider using two units.Unit PlacementA base or foundation is not required if the selected unit location is level and strong enough to support the unit’s operating weight.Isolation and Sound Emission The most effective from of isolation is to locate the unit away from any sound sensitive area. Structurally transmitted sound can be reduced by using spring or rubber isolators. The isolators are effective in reducing the low frequency sound generated by compressors and, therefore are recommended for sound sensitive installations. An acoustical engineer should always be consulted on critical applications. For maximum isolation effect, the refrigeration lines and electrical conduct should also be isolated. Use flexible electrical conduit. State and local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unit placement must be carefully evaluated.Unit LocationUnobstructed flow of condenser air isessential for maintaining condensingunit capacity and operation efficiency.When determining unit placement,careful consideration must be given toassure proper air flow across thecondenser heat transfer surface. Failureto heed these considerations will resultin warm air recirculation and coil air flowstarvation, resulting in a high pressurecompressor cutoff.Warm air recirculation occurs whendischarge air from the condenser fansis recycled back at the condenser coilinlet. Coil starvation occurs when freeair flow to the condenser is restricted.Both warm air recirculation and coilstarvation cause reductions in unitefficiency and capacity. In addition,in more severe cases, nuisance unitshutdowns will result from excessivehead pressures. Accurate estimates ofthe degree of efficiency and capacityreduction are not possible due to theunpredictable effect of varying winds,temperatures and coil conditions.In addition, wind tends to further reducehead pressure. Therefore, it is advisableto protect the air-cooled condensingunit from continuous direct windsexceeding 10 miles per hour.Debris, trash, supplies, etc., should notbe allowed to accumulate in the vicinityof the air-cooled condensing unit. Supplyair movement may draw debris betweencoil fins and cause coil starvation. Specialconsideration should be given to unitsoperating in low ambient temperatures.Condenser coils and fan dischargemust be kept free of snow and otherobstructions to permit adequate air flowfor satisfactory unit operation.Effect of Altitude On CapacityCondensing unit capacities given in theperformance data tables. At elevationssubstantially above sea level, thedecreased air density will decreasecondenser air density will decreasecondenser capacity and efficiency.Ambient ConsiderationsStart up and operation at lowerambients requires sufficient headpressure be maintained for properexpansion valve operation.At higher ambients, excessive headpressure may result. Standard operatingambients are 7-45O C. With a low ambientkit comprising crank case heaters andfrequency inverters, operation below7O C is achievable. Minimum ambientcondition are based on still conditions.Refrigerant PipingSpecial consideration must always begiven to oil retum. Minimum suction gasvelocities must always be maintainedfor proper oil retum. Outdoor Unit Application ConsiderationsOutdoor Unit SelectionSYSTEM PERFORMANCE DATAEWB=Entering Wet Bulb, deg.

IntroductionThis reference design provides a hardware and software solution for Sensorless Brushless dc motors. This document includes complete schematics, printed circuit board layout, and firmware. The Sensorless Brushless dc motor reference design may be used as a starting point for motor control system designers using Silicon Laboratories MCUs, significantly reducing the design time and time to market.Brushless dc motors consist of a permanent magnet rotor with a three-phase stator winding. Brushless dc motors evolved from conventional dc motors where the function of the brushes is replaced by electronics. Brushless dc motors offer longer life and less maintenance than conventional brushed dc motors.Most Brushless dc motor designs historically use Hall effect sensors to measure the position of the rotor. Hall effect sensors provide absolute position information required to commutate the motor. Using Hall effect sensors provides simple, robust commutation and performance roughly comparable to brushed dc motors. One of the major barriers limiting the market penetration of Brushless dc motors has been the cost of using Hall effect sensors. The Hall effect sensors themselves are not particularly expensive. However, the Hall effect assembly adds significant expense to the cost of manufacturing the motor. Hall effect sensors also typically require 5 additional wires, adding to the installation costs.A “Sensorless” Brushless dc motor does not have Hall effect sensors. Sensorless Brushless dc motors employ more sophisticated electronics using some alternative scheme to control the commutation of the motor. The most common scheme involves measuring the back EMF of the motor and using this information to control the commutation of the motor.Most computer hard disc drives use a sensorless brushless dc motor. However, these small motor drives use a linear regulator to control the voltage applied to the motor. This works well for small motors, but is too inefficient to use for motors greater than a few watts. Larger motors require PWM control for efficient operation. Using PWM control makes the task ofmeasuring the back EMF of the motor more difficult, due to noise coupled from the active windings.Sensorless Brushless dc motors are well suited for fans and rotary pumps from a few watts up to about 1 kW. Fans and pumps’ loads are predictable and fairly well behaved. Most Sensorless Brushless dc motors do notprovide the same level of dynamic speed control available from Hall effect controlled BLDC motors or dc motors. While it is theoretically possible to achieve high-performance from a sensorless BLDC motor using sophisticated vector control, most practical sensorless BLDC implementations address the much simpler fan and pump applications. This reference design is targeted for simple fan applications.Sensorless BLDC motor drives often compete against ac induction motors for certain applications. A system designer must consider the power level, efficiency requirements, and starting requirements when choosing between BLDC motors and ac induction motors. BLDC motors are most often used for small motors rangingfrom 1 watt to 1 kW. AC induction motors are readily available from 250 W to 10 kW or more. BLDC motors offer potentially higher efficiency than ac induction motors. This is due to the fact that ac motors have high rotor losses while BLDC motors do not waste energy in magnetizing the rotor. AC induction motors are much easier to start than sensorless BLDC motors. Thecomplexity of starting a fully loaded BLDC motor often makes the ac induction motor a better choice, particularly for piston pumps and compressors.AN2082Rev. 0.22. Theory of OperationBrushless dc motors have a dual personality. To fully understand Sensorless Brushless dc motor control it is necessary to understand both dc motor characteristics and Stepper motor characteristics. When commutated using Hall effect sensors, the torque speed characteristics of the Brushless dc motor are virtually identical to a conventional dc motor. The ideal no load speed is a linear function of the applied voltage. The torque and motor current are at a maximum at zero speed and decrease to zero at the maximum speed. The torque-speed characteristics of a dc motor are shown in Figure 1. Under ideal conditions, the characteristics of a sensorless BLDC motor are similar.The characteristics of a stepper motor are quite different. The motor current in a stepper motor is not proportional to the load torque. The motor winding resistance typically limits the current in a stepper motor. The motor winding resistance of a stepper motor is normally an order of magnitude higher than a BLDC motor. An ideal model for a stepper motor is shown in Figure 2.Figure 2. Stepper Motor ModelThe motor is driven with a constant voltage. When the motor is at a standstill, the back EMF is zero and the current is at its maximum value. As the motor speed increases the back EMF will increase, reducing the voltage across the motor resistance, and the motorcurrent will decrease. The available torque for a stepper motor is proportional to the current forced through themotor windings. The available torque is at its maximum value when the motor is at a standstill. The available torque decreases as the motor speed increases. If the load torque ever exceeds the available torque the motor will stall. Figure 3. Stepper Motor CharacteristicsThe performance of the stepper motor may be improved using a variable voltage drive. By increasing the voltageapplied to the stepper motor in proportion to the velocity,the available torque will remain constant and the fancan be driven to a higher velocity before stalling as shown in Figure 3.A BLDC motor can also be considered as an unusual stepper motor. A 4-pole 12 V BLDC motor is functionally equivalent to a 12-step per revolution stepper motor with a voltage rating of about 1 V. A typical Stepper motor has a much higher step count, higher voltage, and higher resistance. A typical hybrid permanent-magnet stepper motor has a step angle of 1.8º, or 200 steps per revolution. A 12 V stepper motor might have a resistance of 30 Ω, compared to less than 1 Ω for a similar size BLDC motor. The stepper motor is optimized for precise angular positioning and constant voltage drive. The BLDC motor is optimized for Hall effect commutation and variable voltage drive.2.1. PWM SchemeMost Hall effect BLDC motors use a three-phase bridge to drive the motor windings. A Three-Phase bridge isshown in Figure 4.AN208Rev. 0.23Figure 4. Three-Phase BridgeThe most common drive method is to use blockcommutation and apply a PWM signal to only thebottom transistors as shown in Table 1. Depending onthe position of the motor and the Hall effect code, theappropriate step pattern is applied to the motor. As themotor rotates, the step pattern will increment throughthe table entries. Using this method, at any point in timethere is only one top transistor in the continuous ONstate and only one bottom transistor being driven by thePWM signal.Considering the motor phases, one phase is drivenhigh, one phase is being pulse-width modulated, andone phase is open. The open phase is noted in thetable. However, there is a problem using the open-phase to sense the back EMF when pulse-widthmodulating only the bottom transistors.Figure 5. Low-Side PWM Back EMFConsider the BLDC motor winding shown in Figure 5. Inthis case the motor is at the first state of thecommutation table. A pulse-width modulated signal isapplied to phase A, phase B is driven high, andphase C is open. The back EMF that we are interestedin is actually the voltage from phase C to the centerconnection labeled point Y. The problem is that thecenter of the Y connection is not a constant dc voltage.Assuming that the resistance and inductance ofwindings A and windings B are the same, the voltage atpoint Y will be halfway between phase A and phase B.The voltage at point Y will be approximately half thesupply voltage when phase A is driven low. Whenphase A is high, the center point Y will be approximatelyequal to the upper supply voltage. The voltage on theopen phase C is now the voltage at center-point Y plusthe back EMF of the motor. The voltage at phase C isalso clamped to the upper rail by the MOSFET bodydiodes in the inverter bridge. The result is a pulse widthmodulated waveform where the minimum voltage levelis equal to the back EMF of the motor. While it ispossible to filter out the PWM signal or sample thevoltage during the PWM on-time, working with thiswaveform is problematic.A better approach is to use a symmetric PWM scheme.A symmetric PWM scheme is any PWM scheme wherethe active top and bottom transistors are turned on andoff together. The simplest method is to apply identicalPWM signals to the top and bottom transistorsaccording to Table 2. This commutation table is similarto the low side PWM commutation table except that thehigh side transistors are pulse-width modulated insteadof just being turned on.Table 1. Low-Side PWM CommutationTop Bottom OpenA B C A B C Phase0ON PWM C1ON PWM B2ON PWM A3ON PWM C4ON PWM B5ON PWM AAN2084Rev. 0.2During the first state of Table 2, an identical PWM signal is applied to both the A bottom transistor and the B top transistor. The result is that Phase A will go low when Phase B goes high and visa versa. If the A and B windings are balanced, the center point Y will remain mid-rail even though phase A and phase B are being pulse-width modulated. The voltage on phase C is now roughly equal to the back EMF voltage. There may be some residual PWM noise due to the second order effects of unbalanced windings and capacitive coupling. However, the unwanted PWM signal is reduced by at least an order of magnitude, as shown in Figure 6.Figure 6. Symmetric PWM Back EMF3. Back EMF WaveformsMost sensorless BLDC control systems use the back EMF zero crossing time as a control variable for a phase locked loop. Instead of using the zero-crossing time, this reference design measures the back EMF voltage at middle of the commutation period using the ADC and uses the voltage measurement to control the commutation. This method provides higher resolution and always provides a robust feedback signal even asthe motor approaches a stall condition. When using the zero-crossing time as a feedback signal, special measures must be taken when a zero crossing does not fall within the measurement window.The back EMF voltage for three different cases is shown in Table 3. If the voltage and speed are just right the voltage ramp will be centered within the commutation period and the midpoint voltage will measure half of the supply rail. If the voltage is too low or the speed is too fast the voltage ramp will be shifted up and to the right. If the voltage is too high or the speed is too slow, the voltage ramp will be shifted down and to the left. The feedback loop should work to keep the mid-point voltage at mid-rail.3.1. Safe Operating RangeWhen driving a Sensorless BLDC motor from a MCU there are two output variables, the motor Voltage V and the motor speed ω. Figure 7 shows the output voltage verses speed characteristics for a sensorless BLDC motor. Three lines are labeled in Figure 7. The middle line is the ideal “no load” line with V equal to ω times the motor constant K E . This line represents the optimum voltage for a perfect motor with no friction.Table 2.

Output Voltage and SpeedThe maximum current is normally limited by thecapability of the power transistors. The maximum boostvoltage is then the maximum inverter current times thewinding resistance. The upper line in Figure 7 is theideal voltage plus the maximum boost voltage. This linedefines the maximum bounds for safe operation. Thelower line is the ideal voltage minus the maximum boostvoltage. This line defines the minimum bounds for safeoperation. While not intuitive, it is quite possible to getan over-current condition by driving the motor with avoltage that is too low for a particular speed.Figure 8. Safe Operating AreaThe Safe Operating Area for the Sensorless BLDCmotor is shown in Figure 8. Above the maximum line thevoltage is dangerously too high. Below the minimum linethe voltage is dangerously too low. The area betweenthe ideal line and the max line is labeled the positivetorque region. In normal steady state operation, theoutput variables will operate in the positive torqueregion.The area below the ideal line is labeled the negativetorque region. While most simple fan and pumpapplications do not require negative torque, operation inthe negative area is permitted. If the motor speedcommand is decreased, the control system will outputvalues in the negative torque region until the operatingpoint is re-stabilized. While it is possible to prohibitoperation in the negative torque region, this mayadversely affect the stability of the control system.The safe operating area is important because it is veryeasy to exceed the limit using conventional controltechniques. If we ignore the safe operating area anduse a simple PI controller to regulate the output voltage,the control loop will output excessive voltage and thepower transistors may be damaged.If we drive the motor with a voltage corresponding to themaximum line, we are forcing maximum current into themotor at all times. This will provide the maximumavailable torque at all times and it is unlikely that themotor will stall. However, the no load efficiency will bevery low and cogging torque may be a problem.Cogging torque is the variation in torque caused by apulsating electromotive force. Stepper motors aredesigned to operate on the max line with low coggingtorque. Most BLDC motors are not designed for thiskind of operation. Excessive cogging torque can causevibration, noise, and stability problems.This reference design uses a novel control techniqueentitled “Constant Voltage Control with SpeedDependent Limiting”. The goal of this controlmethodology is to provide a simple and robust controlalgorithm using a single control loop while keeping theoutput speed and voltage within the Safe OperatingArea.The control technique is illustrated in Figure 9. Theinput speed control potentiometer controls the targetoperating point indicated by the dot on the ideal line. Ifthe error signal is zero, the output voltage and speedare set according to the speed potentiometer. As thespeed control is varied, the target operating point willvary along the ideal line.The bold line indicates variation in the output voltageand speed due to the error signal. A small positive errorsignal from the feedback control system will result in adecrease in speed while the voltage remains constant.The voltage will remain constant until the speed reachesthe limit set by the maximum line. If the error signal islarge enough to exceed the limit, both voltage andspeed are reduced according to the maximum limit.In a similar fashion, a small negative error signal willresult in an increase in speed. If the negative error isincreased beyond the bounds set by the minimum line,the voltage will be increased.The resulting control loop is very stable. The motor isdriven with a constant voltage, as long as the loadAN2086Rev. 0.2torque and acceleration are within the bounds set by the minimum and max limits. In this region the motor behaves like a dc motor with a constant voltage drive. A small increase in load torque will result in a small decrease in speed.For large positive errors signals, the motor voltage is reduced to keep the current below the maximum limits. In this region the motor behaves as a constant current or constant torque drive.Figure 9. Constant-Voltage with Limiting3.2. Starting One major problem with using the back EMF to control the commutation of a sensorless BLDC motor is that the back EMF is not present or is too small to be useful until the motor is rotating at some minimum speed. Thecommon solution is to drive the BLDC motor like astepper motor to align the motor and accelerate themotor up to some nominal speed. This requires that the control system have multiple modes of operation. While it is generally undesirable to have a control system withmultiple modes of operation, it is unavoidable in thiscase. A common pitfall of systems with multiple modesof operation is instability during the transition from one control mode to another. Special considerations are required in the running stage to ensure system stabilityduring the transitions.The motor state diagram is shown in Figure 10. The system is initially in the STOP state. Pressing the Start button will advance to the ALIGN state. The motor willthen advance automatically to the START and RUNstates. An over-current error will reset the motor to the STOP state. Figure 10. SBLDC State Diagram3.3. AlignmentThe alignment state consists of two stages—the Alignment Ramp and the Alignment Delay. During the Alignment Ramp, one of the motor windings is excited by PWMing the top of one phase and the bottom of another phase. The PWM duty cycle is initially at zero percent and is ramped up to 50% plus the starting boost voltage. The voltage is increased using a linear ramp with a fixed delay time between voltage increments. The current in the motor winding will depend on the motor inductance and winding resistance. For duty cyclesbelow 50% the current will be discontinuous. The current will increase while the transistors are on and decrease to zero after the transistors turn off as shown in Figure 11. The peak and average dc current for duty cycles equal to or less than 50% can be calculated using Equation 1.The PWM duty cycle will always be above 50% while running.I avg I peak VL---d×==AN208Rev. 0.27Equation 1. Peak and Average CurrentFor duty cycles above 50% the current will be continuous. Usually a higher current is desired for alignment. Above 50%, a small change in duty cycle will result in a much large change in average dc current. The starting boost voltage is typically a very small number.The second part of the alignment phase consists of asimple delay. The voltage is held constant for a period oftime. The alignment delay time should be long enough to allow the motor to align to the excited pole position. A one second ramp time and a two second delay time works well for the test motor with no fan. When using a large fan, a time of several seconds may be required. Finding the optimal delay time requires some experimentation.The alignment stage ensures that the motor starts froma known position. Without the alignment stage the motormight miss the first several critical commutations in the starting acceleration ramp. If the motor does not align during this stage a motor stall is more likely in the starting phase.During the alignment stage the system is in a relativelybenign state. The dc current is predictable and wellregulated. The power dissipated in the motor can becalculated from the motor winding resistance. A currentmeasurement is only needed to protect against wiringerrors.Most BLDC motors are optimized for high-speedoperation and have very limited torque in the alignmentphase. This is not too much of a problem for small fans,but it does preclude the use of sensorless control insome other applications. The torque is limited by theinverter current and motor design. Over-sizing the inverter or using a lower speed motor can increase the starting torque.3.4. Starting During the starting phase the BLDC motor is driven like a stepper motor. The motor is commutated at first very slowly and then velocity is increased linearly using a linear velocity ramp table. The voltage is also increasedin proportion to the velocity with additional boost voltageto keep the current at a constant value. The motor winding resistance normally limits the boost voltage.The acceleration ramp table ramps the motor speedover a 30:1 range from 25 to 750 rpm. The maximumvalue of 750 rpm was chosen to be one tenth of the maximum speed of the motor. The closed loop sensorless control will then operate over a 10:1 range from 750 to 7500 rpm. The back EMF at 750 rpm will be one tenth of the rated voltage.The key to getting the motor up to 750 rpm is to use alarge enough acceleration ramp table with a sufficiently large ratio of minimum to maximum. A ratio of 30:1 can be achieved using a table with only 192 bytes of data. This also permits the efficient use of an 8-bit table index. Experimental results using a smaller 16-byte table withan 8:1 range proved unsatisfactory. If the table is too small, the initial velocity will be too fast or the finalvelocity will be too slow.The voltage of the motor is also ramped during the acceleration phase. If the voltage were held constant at the alignment value, the current would decrease during the motor acceleration. Initially the current is only limited by the motor resistance. As the motor starts turning, the back EMF of the motor will subtract from the voltageacross the motor resistance. This results in a decrease in motor current and a corresponding decrease in theamount of available torque.Assuming the motor will accelerate in step with the commutation period, the back EMF will be proportional to the motor velocity and inversely proportional to themotor period. The motor voltage ramp may be calculated by dividing a constant by the value in theramp table. By increasing the voltage during theacceleration phase the motor current can be held at aconstant value. This ensures maximum available torqueduring the acceleration phase.If the motor stalls at any point, the back EMF will be zero, and the assumption of motor velocity is no longervalid. The resulting motor voltage will be too high andthe current may be much higher than expected. This isproblematic for small motors and can be disastrous forlarge motors.The solution is to monitor the dc motor current during acceleration and to shut down if the motor current getstoo high. The back EMF is not sufficiently large to detect if the motor is moving. A current limit is not neededduring the starting phase if the motor voltage is limited to the maximum inverter current times the motor resistance, though this will severely limit the starting torque on all but the smallest motors.3.5. RunningThe minimum Running speed and voltage are dictatedby the starting parameters. In this example, the minimum speed is 750 rpm. The minimum voltage is10% plus the boost voltage. At the lower operatingAN2088Rev. 0.2point, the motor is being over-driven by a voltage that is intentionally higher than necessary for stable closed loop operation. Since the motor is being driven like a stepper motor, the cogging torque and motor vibration will be higher in the starting phase.3.6. Back EMF MeasurementsThe back EMF is measured at three points, as shown in Figure 12. The midpoint voltage is the primary control variable for closed loop control. The two voltage measurements at one quarter and three fourths are used for stall detection. The current measurement is used for over current detection. The time slots are discussed in further detail in the software description.Stall detection is achieved by measuring the voltage at quarter points over two cycles. The difference betweenthe minimum and maximum of these four points is anindication of the back EMF of the motor. If the back EMFis greater than a certain value, we can deduce withreasonable certainty that the motor is indeed running. Ifthe back EMF is too small to give a usefulmeasurement, we cannot know for certain if the motor isstalled or running. Thus, the stall detection operatesonly in the running phase. The example implementationilluminates an LED when a stall condition is detected.4. Hardware DescriptionThe schematic diagram for the Sensorless BLDC Motor reference design is in Appendix A. The circuit consists of the C0851F310 Microcontroller, three-phase power MOSFET bridge, three dual gate drivers, sense voltage resistive dividers, current amplifier, speed control potentiometer, two function switches, USB-UART bridge, and voltage regulator.Port P1 is configured as push-pull outputs and is connected to the three dual gate drivers. The P1 port pins are sequenced, alternating between bottom and top starting with phase A in the least significant bit. P1.0-1.5 corresponds to A bottom, A top, B bottom, B top, C bottom, and C top respectively. This sequence facilitates commutation using a simple pattern with the Crossbar pin skip register.Each of the three output phases are connected to a simple resistive divider. The resistive divider will divide the phase output voltage by six. This ratio permits accurate ADC measurements up to 19.8 volts. The 5 V tolerant port pins offer protection against phase voltages up to 30 Volts. The motor supply is 12 V nominal when loaded with the motor turning at full-speed. The unloaded voltage may climb as high as 18 V for the recommended wall mounted transformer.A capacitor across the lower resistor of each divider forms simple single-pole low-pass RC filter. Each filter is tuned approximately one decade below the PWM frequency. Three test points are provided for the scaled voltages labeled VA, VB, and VC.A forth resistive divider is used to sense the voltage of the motor supply. This resistive divider has a ratio of one to twelve. A test point is provided on the scaled motor supply voltage labeled VM. A phase voltage of 12 volts will produce voltage of 2 V on the respective ADC input, while a supply voltage of 12 V will produce a sense voltage of 1.0 V on the VM ADC input. A differential ADC voltage measurement will be used relative to the VM ADC input. The resulting ADC reading will be a signed 16-bit value with 0x0000 corresponding to mid-rail.The sensorless BLDC motor reference design boardincludes a current sense resistor R25 and currentamplifier U7A. The sense resistor is a 20 m Ω surfacemount resistor in an 1812 package. The sense resistorwas chosen for a maximum RMS current of 5 amps witha power dissipation of 500 mW. The resulting sensevoltage of only 100 mV requires amplification to achievemore than 5 bits of resolution from the 10-bit ADC.The current amplifier is a variation of the classic differential amplifier circuit. In the classic circuit configuration, the second resistors on the non-inverting input would be connected to ground. In this variation,resistor R17 is connected to a 400mV voltage reference. The 0.4V reference compensates for the variation in the input offset voltage of the op amp and also keeps the output within the recommended output voltage range. The gain of 26 was chosen to fully utilize the output voltage span of the amplifier allowing forvariation in the input offset voltage. The op amp chosen for this circuit is the LMV358. This is a low-voltage version of the industry standard LM358 dual CMOS op amp. The second op amp in the dual。

Pressure peaks can be absorbed with a sufficient safety margin.A changeover ball valve between the two filter housings makes it possible to switch from the dirty filter side to the clean filter side without interrupting operation. The filters can be installed as a suction filter, pressure filter or return line filter.The filter element consists of star-shaped, pleated filter material, which is supported on the inside by a perforated core tube and is bonded to the end caps with a high-quality adhesive. The flow direction is from outside to inside.For cleaning the stainless steel mesh element (see special leaflets 21070-4 and 39448-4) or changing the filter element, remove the cover and take out the element. The mesh elements are not guaranteed to maintain 100% performance after cleaning.For filtration finer than 25 μm, use the disposable elements made of microglass. Filter elements as fine as 3 μm are available; finer filter elements are available upon request.Eaton filter elements are known for high intrinsic stability and an excellent filtration capability, a high dirt-retaining capacity and a long service life.Eaton filters are suitable for all petroleum based fluids, HW-emulsions, most synthetic hydraulic fluids and lubrication oils.Ship classifications available upon request.
