12 vdc air compressor for tire inflation and backup for the leveling

Yahoo Message Number: 91413
Hi Coach Owners,

The photos section shows a 12 vdc air compressor and reserve tank. It provides pressure from 150 to 175 psi. Besides tire inflation, a quick disconnect provides connection to the coach's primary tank for backup air. Hookup is provided via alligator clamps to the chassis battery bank or in the engine compartment. The tank is an old scuba diving tank with tapped holes for the compressor input, air output and pop off valve set for 175 psi. The tank end connects to a drain valve and pressure switch set for 150 psi off. A bypass switch allows for pressure up to 175 psi.
