LP_filterfans

A milestone in industrial thermal management

Otto Pfannenberg's invention of the filterfan in 1958 was one of them. Even today, the flat profile, uni-coloured design matches modern machines and plants perfectly.

A filterfan sends cool, filtered ambient air into the interior of the electrical enclosure. At the same time, it increases the pressure slightly, which prevents dust from infiltrating into the enclosure. Fitting a filterfan to the lower third of the electrical enclosure and placing the exhaust filter as high as possible also aids natural air convection processes and avoids the build-up of heat pockets.

Quick and easy assembly

Our exhaust filters are also available in 42 piece packaging for faster assembly. This saves both time and costs. You can easily grab filterfan after filterfan in order to get the installation job done in a very reduced working time. Try it out!

Customised solutions available

Next to the standard RAL 7035, we also offer our (exhaust) filterfans in black colour. Furthermore, Pfannenberg is very happy to offer individual solutions or to develop solutions together with our customers. Just contact us!

Choosing the right filter medium

Whilst the patented 4-corner fastening system enables safe and quick installation, the filter medium can be replaced in seconds - thanks to the "click & fit" mechanism. You can choose between the fluted filter mat or fleece filter mat.

Continuous improvements

As a result of several years of experience and continuous further development, Pfannenberg's filterfans have features which are unrivalled. Thanks to flow optimised fins and rotor blades, the filterfans 4.0 reach a particularly high airflow and, at the same time, the IP 55 protection class.
