Pfannenberg PFA Series Filter Fan for 177 x 177mm Fans, Thermoplastic Frame, 202 x 202 x 40mm

The Pfannenberg Exhaust filter offers secure contact service on the installation cut-out edges without the use of beryllium copper gaskets. It features more secure IP 54 protection with a foam seal and a patented 4-corner fastening system for added stability. The Filterfans is the culmination of 60 years experience in thermal management. Using filterfans is the most efficient and cost-effective way to remove heat from the electrical cabinet at ambient temperatures below target internal. In order to utilize this cost-effective and energy efficient cooling solution, the shielding effect of the electrical cabinet housing for EM radiation is reduced by the installation cut-out. When the EMC filterfan is used, this shield is securely closed via a metal grid so that EM radiation is attenuated before entry and exit.
