The bi - flow filter driers are for use in liquid lines on heat pump or reverse cycle. The device can save two external check valves and two normal filter driers reducing complex lines and cost.
ICEAGE FDK series bi - flow filter driers have built - in check valves which ensure refrigerant liquid always flows from the outer side of the filter core towards the center. Therefore all contaminants are retained irrespective of flow direction.
