The DFFH and DFFHM are designed for applications
in which the filter housing must provide two directions
for fluid flow.
DFFH & DFFHM filters have a filter
head of ductile iron and a screw-in bowl of cold formed
DFFH Reverse Flow models filter fluid in the forward
direction and bypass the filter element when the flow
DFFHM Bi-directional models allow
fluid in filtering in both directions. There is a filter
element when the flow is reversed.
Inlet/outlet port options include
SAE 4-bolt flange (code 62), or SAE ports (DFFHM flange
only) to allow easy installations without costly adapters.
Choice of materials
Screw-in bowl mounted below the filter head requires
minimal clearance to remove the element for replacement;
contaminated fluid cannot be washed downstream when
the element is serviced.
Optional bypass for forward flow
