SYSTEM
1 0 • 3 8 6
The air compressing system on the motorhome is comprised of several
items: an air compressor, air governor, air dryer, a front air tank and a rear air
tank. The compressed air system operates several items, some of which include
brakes, suspension, air horns, air gauge and 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. The moisture laden air
then enters an air dryer where the air is filtered. The filtered air charges the
front air tank. The front air tank is divided in two halves: a wet side and a 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 inline check valves to prevent back flow of compressed air.
