The optimum choice
for filtering out
moisture and contaminants that can lead to
freeze-ups and premature system malfunction.
The Bendix
®
System-Guard
®
trailer air dryer is the first
air dryer designed specifically for trailer brake systems that
continuously protects against moisture and solid contami-
nants, minimizing the possibility of pneumatic seize-ups.
The System-Guard
®
trailer air dryer cleans the air in both
the trailer’s supply and control air lines simultaneously,
helping to protect trailer valves and your trailer ABS. It
helps to prevent contaminants and moisture from entering
air suspension bags and valves that can keep the air
suspension from working correctly, reducing downtime and
decreasing overall maintenance costs. It also incorporates
fail-safe bypass valves in the unlikely event the dryer
becomes obstructed.

An automatic solution, standing guard over open
glad-hands on trailers and converter dollies.
The Bendix
®
Cyclone DuraDrain
™
trailer
water separator is the only trailer air
brake system protection device available
today, that automatically purges liquid
contaminants while simultaneously
removing solid particulate.
At over 90 percent efficient in capturing and removing
water during normal braking applications, the Bendix
®
Cyclone DuraDrain
™
unit can be used on both supply and
control lines.
The patent pending Cyclone DuraDrain
™
is a highly
effective separator designed to help increase the service
life of valves, antilock braking systems and your overall
brake system by preventing contaminants from ever
reaching them. Small but mighty, it can also greatly reduce
internal valve corrosion, system freeze-ups and dragging
brakes.

A fine-grade filter designed
to eliminate the smallest
foreign material before it enters
your trailer air line.

from a trailer air line before it can enter the control port of
the trailer ABS modulator or spring brake relay valve.

removing the smallest particles down to 0.012 inches in
size… helping your trailer air lines and ABS operate to
maximum capacity.
