FIGURE 1 - CYCLONE DURADRAIN™ TRAILER WATER SEPARATOR

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.
