CARTRIDGE FILTER HOUSINGS
Filter for Liquid and Gas Applications
Waterflood Operations, Pollution Control, Glycol and Amine Filtration

The head mounts directly in the flow line. The filter may be mounted in any position. Fluid enters one side of the filter head and is channeled to the area around the filter cartridge. The fluid or gas passes through the cartridge into the center and out the other side of the head. The single piece body is sealed to the head by a fixed rigid center rod and T-handle closure nut. As the T-handle is tightened, the body and cartridge are firmly sealed against the head and gasket.
The T-handle, standard on the 1L series, is an option on many other brands. Each model has, as standard, a plugged 1/8” internal pipe thread drain in the bottom of the body.

STANDARD CONSTRUCTION FOR 1L AND 1LU HOUSINGS
The cast head of the 1L series cartridge filter housing has 1 inch, in-line, internal pipe thread inlet and outlet connections. The tubular body and welded end closure are made of either carbon or stainless steel. All wetted parts of the 1L series are cast/carbon and the 1LU series are stainless steel. The Buna shell gasket
is held in place by a machined groove in the head which seals between a T-handle nut and head. The head and body are pulled together by the T-handle nut threaded to a rigid, fixed center rod which is an integral part of the body. As the T-handle is turned, the body is sealed firmly to the head. The T-handle closure feature eliminates the need for wrenches or tools. The cartridge is sealed in place as the T-handle is tightened.

The 1C model holds one 9-3/4 inch long cartridge. The  2C models use either two stacked single length 9-3/4 inch cartridges or one single 19-1/2 inch length cartridge. The 3C model holds one 29-1/4 inch long cartridge or three single length 9-3/4 inch cartridges. The 4C model holds one 40 inch long cartridge.

All models have a knife edged stand welded to the body center rod which creates both a positive cartridge seal and a contaminant sump area. All housings include one set of filter cartridges. All models are available for 200 psi working pressure at a maximum temperature of 250 °F.
