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 
glad-hand.  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 glad-hand 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.
