Frame  Purolator F312 frames are produced using post-consumer recycled materials

The unique Monobond pinch frame concept involves a one-piece frame sealed to the media under heat and pressure

This construction feature produces a continuous bond of media to board around the periphery of the frame, eliminating weak corners and air bypass

The use of a high tensile strength polyethylene binder increases the integrity of the seal, allowing the filter to withstand varying temperatures and humidity levels

Media  Purolator F312 filters are manufactured with superior grade fiberglass media to guarantee full depth loading and high dust holding capacity

A computer-controlled manufacturing process assures a uniform gradient density pattern in the media

To enhance filtration capability and prevent migration of finer particles, the filter media has a skin backing and is evenly coated with a gelled adhesive

Purolator's F312 filters perform best in conditions where large quantities of lint and dust are present

The rugged construction makes these filters industry leaders in the high velocity system, prefilter market

Improved aerodynamics reduce restriction to air flow

Safe, easy, fast installation

Larger effective filtering surface area
