Fig. 1 Function
The intended purpose of the PWEAAC/AP condensate drain is to discharge con
densate from compressed air systems. The condensate flows through the feed
pipes 1to the PWEAAC/AP and collects in the housing 6. A capacitive sensor
2continuously monitors the fill level and sends a signal to the electronic control
ler when the reservoir is full. The pilot valve 3is actuated and the diaphragm
4opens the drain pipe to discharge the condensate 5. If the PWEAAC/AP is
emptied, the drain pipe is closed before a loss in pressure can occur. The device is
not intended to be used with fluids and gases.
