CHASSIS INFORMATION
DIPLOMAT 2004
The air dryer is located underneath the motorhome next to the
transmission. The air dryer removes moisture from the compressed air
system. This is important because if air contains moisture it can freeze and
prevent operation of brakes or other pneumatic operated items.
The air dryer has three functions: cooling, filtering and drying the air
going through the motorhome's air system. If an excessive amount of water
is present when performing the monthly air tank drain service, it may be an
indication that the filter for the air dryer needs to be changed.
Operation:
During system pressure build-up, compressed air passes into the air dryer
where the filter system removes contaminants and passes the air into the
drying stage. When the compressor unloads, the water is expelled and the
dry air flows back through the dryer, drying the desiccant for the next cycle.
Initially, moisture condenses in the base of the dryer. Moisture-laden air
passes through the desiccant bed in the air dryer cartridge and is dried.
• The compressor intakes water vapor with the air. The water
vapor condenses as it cools.
• The air dryer prevents water accumulation in air lines that could
damage seals and valves and wash away lubricants.
• The air dryer also prevents water in the air lines that can freeze
and damage air system components.
