No Waste Float Drain, 1/2"NPT/BST

It is often used to automatically remove accumulated water at the bottom of pipelines, refrigerated air dryers, oil-water separators, air storage tanks and the bottom of various air filters. It can be installed in places where it is inconvenient to discharge sewage manually, such as high places, low places, and narrow places; especially in places with large gas consumption and frequent water discharge, it can prevent the compressed air from being forgotten due to artificial drainage. Water is re-polluted.

Condensate from the filter will flow beside the vent tube and accumulate in the drain reservoir. As the condensate accumulates the liquid will cause the float to rise and force air out through the tube and discharge valve expelling the liquid. After the liquid is expelled the float will return to the low position and the discharge valve will closes until the cycle is repeated. Each float type ball drainer is equipped with an “Anti Air Lock” vent tube which prevents loss of compressed air.
