Technical Support
At AIRman Products, we stand behind the pneumatics we sell and we are here to support your technical needs. If you are experiencing technical issues, please review the recommended maintenance tips and general troubleshooting topics below. If you are still experiencing technical issues, please contact us at sales@airmanproducts.com and one of our associates will contact you.
Maintenance Tips
- Any pneumatic product will last longer by keeping your air lines free of water, dirt, and contamination. Drain tanks regularly and use 40 micron filters wherever practical.
- AIRman Products valves and cylinders will provide many years of trouble free service if they are periodically re-lubricated (at least twice a year in Spring and Fall recommended). Re-lubricate with a silicone based lube oil through the glad hand or valve/cylinder supply ports.
- Do not use de-icing fluids in any pneumatic product, as they will cause seal damage. If it is absolutely necessary to do so anyway, be certain to re-lubricate your system immediately afterwards with a silicone based lube oil.
General Troubleshooting
- Leaks: If the system appears to be leaking or is suspected,
- Fittings: verify that all fittings are tightened properly to not provide leak at the ports.
- End caps: verify that end cap screws are tightened properly and that o-rings are in place for any air pilot or solenoid operators.
- Application Specific
- Lift Axle: Be certain that your supply pressure does not exceed the bag manufacturers maximum rated operating pressure.
- Valves
- Air Pilot Supply: Most of AIRman Products’ valves with an air pilot operator, or external pilot supply to a solenoid, must have a minimum of 55 psi pilot signal. Internal pilot supply may need to be 65-75 psi for proper operation depending on valve usage. Certain valves are unique and may have different required pressures, so check the individual valve data sheet for pilot signal pressures as needed.
- Pressure protection valves are used to prevent loss of pressure in the main air brake supply system in the event of a leak in accessory systems such as lift axles, suspension components, tailgate latch controls, etc. If there is a gross leak in the system ahead of the PPV, the system will not function and the PPV is working as intended.
- Cylinders
- Single acting cylinders will return to the normal position upon loss of air pressure.
- Double acting cylinders must have air pressure at all times to maintain position.
