P312 Filters - Construction

P312 panel filters are made of polyester media that is developed for situations where synthetic media products are required. P312 disposable synthetic panel filters are ideal for residential, commercial, and light industrial use and can be used as a replacement for F312 fiberglass filters.

Frame - P312 panel filters are framed using post-consumer recycled materials! The unique Monobond pinch frame concept involves a one-piece frame sealed to the media under heat and pressure to produce 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 binder increases the integrity of the seal, allowing the filter to withstand varying temperatures and humidity levels.

Media - P312 disposable panel filters are made with synthetic media that consists of polyester fibers bonded together in an interlocking pattern of tiny lint and dust traps. This configuration maximizes dust loading while minimizing resistance to airflow and surface loading.

Application - P312 panel filters perform best in conditions where large quantities of lint and dust are present. Because of their rugged construction, P312 disposable panel filters are an industry leader in the high velocity system, prefilter market.
