Filter Fan Kits · DNFF Series

Key Features and Benefits

The DNFF Series Filter Fan Kits provide reliable cooling while helping protect sensitive electronics from dust and airborne contaminants. By combining a high-quality AC fan with an IP5X-rated replaceable filter, the DNFF Series delivers clean airflow that helps maintain safe operating temperatures inside industrial enclosures, electrical cabinets, and rack systems.

Designed for hard-wired installations, the DNFF Series is ideal for OEM equipment, industrial automation, telecommunications, and control panels where permanent wiring is preferred. Available in multiple fan sizes, voltages, and airflow ratings, each kit includes everything needed for installation, while replacement filter media makes long-term maintenance simple. Complementary XPFA exhaust filter grilles are available for balanced enclosure ventilation.
