Series 52 -Instruction Manuel

The air filter removes impurities from the airstream two ways: dynamically by centrifugal force, by which the deflector throws out heavier particles and entrained water; and statically through the filter element itself, which filters out the smaller particles. The filter provides enough filtration for most pneumatic applications; however, in situations where water and/or oil aerosols must also be filtered out, a coalescing filter should also be installed. 

Installation 

1. Depressurize and lockout air pressure. 
2. Upstream pipes must be free of excessive dirt and liquids. 
3. Install the filter as close as possible to the device it is to serve. 
4. Install the filter so that air flows in the direction of the arrow on the filter cap. 
5. The filter must be installed vertically with a drain knob at the bottom. 
6. Filter should be installed upstream of any regulators or lubricators in the compressed air system. 

Operation 

1. For manual drain models: Periodically drain to discharge accumulated liquids by turning the drain knob clockwise. Return to full counterclockwise position. 
2. For automatic drain models: Filter may be drained manually by turning the drain knob clockwise until bowl drains. Return to full counterclockwise position for automatic drain operation. 
3. To install 3/16 I.D. flexible tubing, push drain knob up to expose the drain clip. Remove the drain clip and drain knob. Push tubing on the stem. A tube clamp or zip tie should be used to retain tubing on drain stem. 
4. Replace the element when dirty. If pressure differential reaches 8 PSIG, the element MUST be replaced. 

Maintenance

1. Depressurize and lockout air pressure. 
2. Remove bowl ring and bowl assembly by turning counterclockwise. 
3. Remove sleeve assembly by pulling off. 
4. The filter element can now be removed.  Elements may be cleaned by soaking several hours in soap and water, then drying them in the reverse direction to normal flow with clean, dry compressed air. However, it is strongly recommended to replace elements to ensure filter efficiency. 
5. To service manual or float drain, remove bowl baffle from bowl assembly. Turn drain knob counterclockwise until it stops. Then push drain knob up to expose drain clip. Remove drain clip and pull off drain knob. 
6. Remove drain nut by turning counterclockwise. The drain can now be removed from bowl and disassembled. 
7. The drain and bowl can now be cleaned.  
8. When re-assembling, be sure all o-rings are correctly located. Lubricate o-rings with lithium grease. Bowl baffle must be installed in correct orientation. Torque drain nut 5-15 in-lbs. Torque bowl ring hand tight. 
9. If the filter cannot be repaired by cleaning with soap and water, the parts should be replaced. 

Bowl Drain 

1. Manual drains are the simplest bowl drain, but they require frequent attention to rid the bowl of accumulated water and dirt particles. If a filter is located where it is difficult to access, it might not be drained as often as it should be. 
2. Automatic drains are used for continuous flow applications where pressure drop might only occur at the start of the duty cycle. When liquid is present the float will rise, and the bowl will empty. 
3. Operating pressure: 30 PSI (minimum) and 200 PSI (maximum). 

The air filter removes impurities from the airstream two ways: dynamically by centrifugal force, by which the deflector throws out heavier particles and entrained water; and statically through the filter element itself, which filters out solid particles.
