Filterfans® from Pfannenberg

Deliver cool and filtered air for thermal management of electronic enclosures

Pfannenberg USA offers a complete range of innovative Filterfan® units used to provide cool and filtered ambient air to electronic enclosures. An economical method of cooling, Filterfans® combine a forced air cooling system utilizing outside air with an air filter. The air propelled by a Filterfan® system into the cabinet displaces the warm air which exits through an exhaust filter.
