Universal Air Filter 800-541-3478 FP-3 Air Filter Element

The Universal Air Filter 800-541-3478 FP-3 is a cleanable, reusable air filtration element designed for industrial and telecommunication equipment requiring compact environmental protection. It is part of the FP-series foam-based filter media range and is intended for use in enclosures, electronic housings, and forced-air cooling systems where controlled airflow and particulate filtration are required.
The FP-3 filter utilizes open-cell polyurethane foam media designed to provide high dust arrestance with low airflow resistance. The structure allows effective capture of airborne particles while maintaining stable airflow characteristics for cooling fans and ventilation systems. The media can also provide limited moisture resistance depending on installation conditions, helping reduce the ingress of airborne mist and dust in protected equipment enclosures.

The filter is typically installed in fan openings or ventilation panels using a framed or clipped mounting configuration, enabling straightforward replacement and maintenance. It is suitable for applications in telecommunications cabinets, electronic control systems, and industrial automation equipment where compact filtration solutions are required. The FP-3 design is optimized for confined spaces and continuous operation environments with moderate to high dust exposure.

Manufactured as part of Universal Air Filter’s custom and OEM-oriented filtration solutions portfolio, the FP-series supports configurable dimensions and integration into various enclosure designs. The filter is intended for long service life with periodic cleaning and reuse, reducing maintenance frequency in comparison with disposable filter media.
