The Purolator MERV 4 F312 Disposable 1 Inch Fiberglass Panel Filters are designed to withstand the demands of tough industrial and commercial applications. Purolator assures filter durability by utilizing construction features not found in traditional designs.

The Purolator F312 frames are produced using post-consumer recycled materials. The unique Mono bond 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.

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.

Underwriters Laboratories, Inc. Classification: F312 filters are classified U.L. Class 2 per U.L. Standard 900.
