Wright-Austin Model 300 Series-AC
Cast Iron Float Style Drain Traps

ARCHIVE PAGE ONLY

EFFECTIVE JANUARY 2019 THE MODEL 350 HAS BEEN DISCONTINUED

Wright-Austin Model 350 float drain trap is designed to remove gummy fluids and varying volumes from pipelines.  

300 series valve diagram“THREE TRAPS IN ONE” is the basic principle of these ball float traps. Three valves open and close progressively as condensate volume varies.

As the float chamber water level rises, the float lies deep in the water until its buoyancy overcomes the opposing line pressure and snaps the valve wide open. When closing, as each valve approaches its seat, the line pressure snaps it tightly closed. These traps have cast iron bodies, and stainless or copper internal parts.

A small amount of water remains within the trap, creating a liquid seal and keeping the valve closed tight, so if installed where freezing can occur, you can order them with a 100 watt, 120 volt heating element, P/N 9014D.
