Wright-Austin float style drain traps provide an economical method for draining condensate and fluid from gas/liquid separators for pressures up to 500 PSI without allowing compressed air and steam to escape with it.

Water enters the trap from the topside and builds-up within the trap body.  The float rises with the water level and when it gets high enough the float opens a valve.  Water is expelled from the bottom and the float quickly comes back down, closing the valve before any air or steam is allowed to escape. A small amount of water remains within the trap, creating a liquid seal and keeping the valve closed tight. Internal parts, including the valve and seat, are corrosion-resistant, non-magnetic stainless steel.

If installed in areas where freezing is a concern consider ordering a heater to prevent the retained water from freezing.
