The F312 disposable panel filters are engineered for tough industrial and commercial environments. Purolator ensures durability by incorporating advanced construction features not found in traditional designs. These filters are built to perform reliably in high-velocity systems and applications with large volumes of lint and dust.

• Frame: Made from post-consumer recycled materials using the Monobond pinch frame concept—a one-piece frame sealed to the media under heat and pressure. This creates a continuous bond that eliminates weak corners and air bypass. A high tensile strength polyethylene binder enhances the seal's durability, allowing performance in varying temperatures and humidity levels.
• Media: Constructed with superior grade fiberglass for full-depth loading and high dust holding capacity. A computer-controlled manufacturing process creates a uniform gradient density pattern. The media features a skin backing and is coated with a gelled adhesive to enhance filtration efficiency and prevent migration of fine particles.
• Application: Ideal for use in areas with high concentrations of lint and dust. Its rugged design makes the F312 a top choice for prefilter applications in demanding, high-velocity HVAC systems.
