Convenience of Design

The 3M™ 1A1 Series Filter Housing is manufactured using an all metal, two-piece construction for lasting durability and service life.  It has a lightweight, rugged die-cast aluminum head and sump and a stainless steel center post for lasting durability where it counts. When needed, a mounting bracket, sold separately, aligns easily with the pre-drilled holes and includes self-tapping screws that eliminate the need for more drilling and fitting work. To help ensure against bypass, leaks and pressure loss, shouldered seal plates fit solidly into the cartridge core for a positive cartridge seal. The stainless steel center post conveniently lifts out for easy cleaning, which helps maintain cleaner systems and maximizes product life.

As process requirements evolve and grow you will appreciate the convenience of the design as you assemble, disassemble, clean and perform periodic maintenance. The housing assembly utilizes 3/8″ NPTF horizontal inlet/outlet connections that help provide flow rates up to 6 GPM, to accommodate a wide range of applications.
