CFM values are fan blowing into the enclosure and out through an exhaust filter, which keeps the cabinet under positive pressure. Pfannenberg free-air CFM is higher and is what our product titles show. Sizes in inches. Data from the Pfannenberg filter fan competitor comparison. Confirm the current datasheets before you release a drawing.
What to check before you swap
Most Hoffman HF sizes drop into the same cutout. HF04, HF05, HF09 and HF10 match the Pfannenberg cutout to the hundredth of an inch. The HF13 cutout is 11.50 in square and the PF 6x000 cutout is 11.46 in, so the Pfannenberg fan fits the existing hole. The HR16 top mount fan uses a 10.43 x 13.68 in cutout. The PFT top mount fan needs an 11.50 in square cutout, so plan a new cutout or an adapter plate there.
Pfannenberg tested the Hoffman fans with its own procedure. At IP54 the Hoffman fans moved less air than published on most sizes (for example HF13 484 CFM: 417 published, 285 tested). The HR16 top mount fan does not carry an IP54 rating, so an enclosure built for IP54 would be derated to IP44. Pfannenberg PF fans with the fluted filter hold the same CFM at IP55 as at IP54. Most PF sizes also come in NEMA 3R.
Common questions
What Pfannenberg filter fan replaces a Hoffman HF10?
PF 43000 is the closest match: 122 CFM at IP54 through an exhaust filter, in the same 8.78 in square cutout. PF 42500 is the lower flow option at 74 CFM.
Will a Pfannenberg fan fit my existing Hoffman cutout?
Yes for HF04, HF05, HF09, HF10 and HF13. The cutouts match, or the Pfannenberg cutout is slightly smaller. The HR16 top mount fan uses a different cutout than the PFT top mount fan.
Do Pfannenberg filter fans hold IP55?
Yes. With the fluted filter, PF 22000 through PF 67000 carry the same CFM at IP55 as at IP54.
What voltages are available?
115 and 230 V AC on every size. 24 V DC up to the PF 43000. 48 V DC on PF 22000. 400/460 V AC on PF 66000 and PF 67000.
