EverFlow
®
Module
The EverFlow
®
air dryer module is used for air dryer
systems where a vehicle needs a continuous fl ow of
air, such as for bulk unloaders and central tire infl ation.
As stated earlier, air dryers need to go through a purge
cycle periodically to refresh the moisture-removing
desiccant material. EverFlow
®
air dryer modules
have two air dryers plumbed in parallel that take turns
supplying air, resulting in a continuous, uninterrupted
supply.
System-Guard
®
Trailer Air D ryer
The System-Guard
®
trailer air dryer removes moisture
and contaminates from the trailer air system. It is
designed to protect the trailer air brake system when,
for short periods of time, the trailer is pulled by vehicles
without an air dryer or during times when the trailer
is disconnected from the tractor. It does not take the
PuraGuard
®
Filters
The PuraGuard
®
QC oil coalescing filter (and its
predecessor PuraGuard
®
system fi lter) are for high
air use vehicles such as transit buses and refuse
trucks. Installed downstream of the air dryer, these
fi lters use a replaceable fi lter element mounted within
a sump housing to remove oil aerosols before they
can enter the air system. A drain valve allows periodic
maintenance.
Cyclone DuraDrain
™
Trailer Water S eparator
The Cyclone DuraDrain
™
trailer water separator is
installed in the trailer control and/or supply lines near
the gladhands. It self-purges liquid contaminates,
contains solid contaminants and improves the life of
the trailer system components.
AF-3
™
In-line Air Filter
The AF-3
™
in-line air fi lter screens out foreign material
from trailer air lines.
Air Dryers and Filters
The AD-SP
®
air dryer uses a small amount of air from
the supply and front axle (secondary) reservoirs to
perform the purge function. Because of this difference,
the AD-SP
®
air dryer is smaller and lighter than air
dryers that have their purge volume within the dryer
canister. An SC-PR
™
Single Check Protection Valve
is used in conjunction with the AD-SP
™
air dryer. The
SC-PR
™
single check protection valve is a combination
of two separate devices, a single check valve and a
pressure protection valve that allows limited fl ow in the
opposite direction. It serves as a means of protecting
the air pressure in the front axle service reservoir,
since it will only allow its air supply to be used to help
purge the AD-SP
®
air dryer if the pressure is above a
certain preset level.
