My HWH compressor is not functioning. Has anyone plumbed in an auxiliary and what pressure do the bags take?
Your original HWH compressor may be fixable or rebuildable. Have you done any trouble shooting?
Several members have installed new replacement air compressors in their coaches. Some use 12 volt compressors- some use 110 volt compressors. Search the Forum for pertinent threads.
Note: Any air compressor used to air up coach system should include a water filter to dry the air.
Your air bags can "take" any pressure up to and including the normal max air system pressure for your coach - around 120-130 psi (same as engine compressor cut-out pressure).
The air pressure going to your
front 6-pack manifold is controlled by the pressure regulator mounted under the front of your coach near the two air tanks.
