Air Dryer - Chevrolet 2005 T-Series Owner's Manual

Air Dryer

If your vehicle has air brakes, it will have an air dryer.
This collects and removes dirt, moisture, or other foreign
matter from the air prior to entering the brake system.
The air dryer also serves as a moisture ejector. It
automatically ejects the moisture when the compressor
cycles. The purge tank is equipped with a manual
drain valve that must be drained every day. See "Air
Brake Systems" for the manual drain procedure.
The dryer is mounted on the passenger side frame rail.
Your dryer is a
Bendix-Westinghouse
model that has a filter that
you need to change at
intervals. See Scheduled
Maintenance on page 6-5
for more about servicing
this filter.
Electric Air Compressor
Your vehicle may have an electric air compressor. This
compressor is used to run options that require
pressurized air, such as air horn, air seat, exhaust
restrictor, or an exhaust brake.
The air compressor is used when vehicles are not
equipped with an air brake system.
It is recommended that this system be drained on a
weekly basis.
The air supply for this
system must be
maintained by releasing
the drain valve to eject any
moisture that may have
built up in the system.
