Did you know Otto Pfannenberg invented the Filterfan® in 1958?
Is your ambient temperature always lower than the temperature required in your electrical enclosures? If so, Filterfans® are a cost-effective solution!
Tips when using Filterfans®:
Use them to force surrounding air into your electrical enclsoure.
The surrounding air enters the electrical cabine exclusively via the Filterans® which makes sure it is filtered.
Intall the Fitlerfans® in the lower third of your enclosure and the exhaust filter as close to the top as possible. This aids in the natural convection of the air and avoids hot spots!
