AIR SUPPLY SYSTEM
The air compressing system on the motorhome consists of: a compressor, governor, dryer, front tank and a rear
tank. The compressed air system operates several items, including brakes, suspension, air horns, air gauge and
the stepwell cover. The air system is charged by a gear driven air compressor mounted on the engine. As engine
speed increases, compressed air output increases. When the air is compressed, heat is generated. Heat dissipates
as the air is discharged from the compressor. Moisture condenses in the compressed air as it cools and enters the
air dryer to be fi ltered. The fi ltered air charges the front air tank, which is divided in to a wet and dry side. The
compressed air enters the wet side before entering the dry side. A discharge line from the dry side of the front air
tank charges the rear air tank. Discharge lines use in-line check valves to prevent a back fl ow of compressed air.
The pneumatically operated items are divided into two categories: brakes and accessory air. Brakes have full use
of supplied air pressure. Accessory air items, such as the air horns or stepwell cover, receive air through pressure
protection valves (PPV). The PPV will not allow compressed air fl ow until the system reaches approximately 60
psi. In the event of an air system problem, the pressure protection valve will leave a reserve air charge for braking.
The pressure protection valve is installed for safety.
Air Governor
The air governor, located in the engine compartment, regulates the
air compressor to cut-in and cut-out, keeping the air system in the
specifi ed operating range of 110 to 135 psi, and sending an air “purge”
signal to the Air Dryer.
When cut-out pressure is reached, the governor will send an air
purge signal to the Air Dryer. This opens the purge port of the Air
Dryer, expelling moisture. The purge action of the Air Dryer is
identifi ed by the short release of air at the rear of the motorhome.
