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. Kooltronic CFM through an exhaust filter is from the fan maker curves in the Pfannenberg competitor comparison. Confirm the current datasheets before you release a drawing.

What to check before you swap

Every Kooltronic cutout here is the same as or larger than the Pfannenberg cutout except the KBFF20: 11.45 in against 11.46 in for the PF 65000, a 0.01 in difference. The KBFF12AUN at 31 CFM is a little above the PF 22000 at 28 CFM. If the heat load is tight, run the numbers in the heat load calculator or step up a size.

Pfannenberg PF fans from the PF 22000 up use a fluted filter. It holds the same CFM at IP55 as at IP54, so compare the IP55 column if your spec calls for IP55. Pfannenberg NEMA 3R filter fans come in RAL 7035 light gray or black.

Common questions

What Pfannenberg filter fan replaces a Kooltronic KBFF15AUF?

PF 43000: 122 CFM through an exhaust filter at IP54 and IP55, in the same 8.78 in cutout.

What replaces a Kooltronic KBFF12AUN?

PF 22000: 28 CFM at IP54 and IP55 in the same 4.92 in cutout. The Kooltronic fan is 31 CFM by the fan maker curve, so check the heat load. PF 22000 also comes in NEMA 3R and 48 V DC.

What does the X in KXBFF mean?

Kooltronic uses K(X)B where X is 2 for the 230 V AC fan. Send the full catalog number and we match the Pfannenberg voltage.

Does Kooltronic publish CFM through an exhaust filter?

The Kooltronic catalog shows free-flow CFM. The CFM here is fan plus exhaust filter from the fan maker curves, so it is lower than the catalog number.
