Air Intake Filter; Oil Cooler - Speedaire 40HU29 Instructions Manual

Air Intake Filter

Never run the compressor pump without an intake air filter or with a clogged intake air filter. The air filter
element should be checked monthly (see Figure 14). Operating compressor with a dirty filter can cause high oil
consumption and increase oil contamination in the discharge air. If the air filter is dirty it must be replaced.
In case of heavily soiled intake air, replace and check more frequently.
1. Switch off the screw compressor system
and prevent it from being switched back
on without authorization.
2. Screw off the wing nut and remove the
filter cover.
3. Remove the old filter element.
4. Carefully remove dust from the filter
housing.
5. Insert the new filter element in the filter
housing.
6. Install the filter cover, ensuring proper
positioning during assembly.

8. Switch on the system.

Oil Cooler

Weekly, check the oil cooler to be sure all fittings are secure and tight. Clean all dirt, dust and other
accumulations from the coolers heat exchange surfaces.
Components
Turn off all power and clean the air end, motor, fan blades, air lines, oil cooler and tank on a monthly basis.
Belts
Check belt tension every 3 months. Adjust belt tension to allow 3/8 inch deflection with normal thumb pressure.
Also, align belts using a straight edge against the face of the pulleys and touching the rim on both sides of the
face. The belts should be parallel to this straight edge.
Slots in the bed-plate allow for sliding the motor back and forth to adjust belt tension.
