Pfannenberg’s Outdoor Series 3R Filterfan® provide electrical enclosures with protection against ingress of falling dirt, harmful effects of rain, sleet, snow and external ice formation. The Filterfan® also features UV resistance plastic to prevent premature degradation from direct sunlight. Pfannenberg’s Outdoor Series 3R Filterfan® also eliminates the component cost and labor for installing a rainhood.

The Outdoor Series 3R Filterfan® reaches a particularly high airflow with flow optimized fins and rotor blades. The fluted filter-mat provides triple service life by holding more dust before airflow is impeded, extending the mean time between maintenance (MTBM) for outdoor enclosures. The new series offers 11 patented features, including a patented 4-corner fastening system that allows toolless installation in seconds in most enclosure wall thickness.

Pfannenberg’s Outdoor Series 3R Filterfans® are offered with eight different airflows in multiple sizes and voltage (AC & DC). They are also available in two colors – black and light grey. The family includes matching exhaust filters for a complete setup for your enclosures. They are UL listed, NEMA, CE and RoHS compliant.

Now that warmer temperatures are upon us, keeping your application up and running can be a challenge. If you need your Outdoor Series 3R Filterfan® right away, don’t sweat it. For more information on the 24 Hours Filterfan® Program, visit
