Filter fans for a safe and reliable enclosure air circulation


SOLIFLEX filter fans and exhaust filters effectively ventilate enclosures and control panels if the ambient temperature is lower than the internal enclosure temperature. Our filter fans come in an attractive plastic housing and are available for both AC and DC voltages. 

All dimensions and enclosure cutouts correspond to the market standards. The integrated filter mats inside the filter fan and outlet filter effectively prevent the inside of the enclosure from becoming dirty. Seifert filter fans can be installed without tools, and the filter can also be easily replaced. SOLIFLEX filter fans are also available with reversed air flow and as NEMA 3R (IP 55) models.

Our new roof mounted filter fans are ideal for applications where there is no space on enclosure doors or walls.
