AIR DRYER
The air dr yer collects and removes moisture and
contaminants before the air reaches the first reservoir. It is
distinctly different than a reservoir drain valve or aftercooler
in that it provides “dry air” for the air brake system. The
daily draining of the system’s reservoirs is no longer
necessary, thus reducing maintenance considerably when
compared to an air brake system without an air dryer.

daily draining of the system’s reservoirs is no longer
necessary, thus reducing maintenance considerably when
compared to an air brake system without an air dryer.
In a system without an air dryer, the life of air brake
components is substantially reduced because of contact
with water and oil in the system and since the air dryer
removes water and oil in vapor form, life of the component
devices is substantially increased when the air dryer is used.

The air dryer can be used on most highway vehicles where
normal compressor loaded time is 90 seconds or less and
unloaded time is 30 seconds or more. If the compressor
remains loaded for long periods of time, such as on a transit
bus, certain changes in the purge volume of the dryer must
be made. For more information regarding increase of the
purge volume, contact our Engineering Department, in Elyria,
Ohio.

The air dryer is installed in the discharge line between the
compressor and the first reservoir. The unit must be mounted
vertically and mounting brackets are provided and can be
adjusted to meet installation requirements.
