Pfannenberg PF filterfans and matching exhaust filters for control panels, from the PF 11000 at 17 CFM up to 560 CFM, rated UL Type 12 with a Type 3R outdoor series. Each size comes in 115 V and 230 V, standard or reverse (exhaust) flow, and black or light gray. Applied Control is the Pfannenberg manufacturers representative.
A filterfan works when the air outside the panel is cooler than the air you want inside it. Run the numbers first with the enclosure heat load calculator: if the ambient is too hot or the air is dirty or oily, step up to an enclosure air conditioner or a heat exchanger instead. Send the catalog number, or the CFM, voltage and cutout size, or the Hoffman or Rittal fan part number you use today, and the quote comes back the same business day.
Filter fan cross references by brand: Hoffman, Rittal, Saginaw, Thermal Edge, Kooltronic, Seifert, Finder and Fandis.
