Emerson Flow Control (Alco) 043337 Bi-Flow Drier 1/2" ODF BFK-164S

Emerson Flow Control (Alco) 043337 Bi-Flow Drier, model BFK-164S, is a liquid line filter drier specifically used for heat pump systems. This part has a 1/2” ODF connection size and works effectively because it allows flow in both the forward and reverse direction, with no need for check valves. The BFK-164S has a high moisture and acid removal capacity that is useful for HVAC systems that need reliable filtration under any conditions. It is designed with a maximum working pressure of 680 psig and filters as low as 40 microns, which means that the contaminants are well separated from the refrigerant.
