Bendix ® Cyclone DuraDrain ™ Trailer Water Separator
DESCRIPTION
The Cyclone DuraDrain ™ trailer water separator can be
installed in the trailer control or in the supply line near the
gladhand. It removes water and contaminants that can
cause brakes to drag and improves the life of the trailer
system components.
OPERATION (See Figure 1)
Compressed air enters the supply port of the Cyclone
DuraDrain
™ trailer water separator. The air pressure pushes
down on the check valve contained in the purge nut and
closes the purge nut drain port. When air enters the supply
port of the Cyclone DuraDrain
™ trailer water separator a
cyclonic action is created.
The cyclonic motion separates the oil, water and particulates.
The oil, water and particulates gravitate to the bottom of the
Cyclone DuraDrain
™ trailer water separator where they
collect. When the air pressure above the purge nut check
valve returns to atmospheric pressure, the check valve moves
up and off its seat. The contaminants then drain through
the purge nut drain port.

If water from a gladhand enters the supply port and no air
pressure is applied, gravity will allow the water and
contaminants to drain through the purge nut drain port.
