EMC filter fans for control cabinets

11 April 2001 Circuit & System Protection

The special features of Seifert's new EMC filter fan system are the result of original design - a fan generation to meet the toughest EMC requirements. As the EMC screen of the model range has a common geometry, all four types offer the same high suppression values. In the critical frequency range up to 300 MHz, the EMC fans provide high suppression values between 80 and 100 dB. At high frequencies of 10 GHz, 40 dB can still be guaranteed, which is far in excess of what conventional fans can provide, according to Seifert.

The design provides a double defence against dust and water penetration (IP54). The self-adhesive seals on the mounting frame provide a seal between the fan and the cut-out in the cabinet. The specially designed cover with its downward facing laminations protects the fan from vertically falling dust or water.

Units with four air volume capacities from 21 to 170 m3/h (unrestricted) are available. A change from suction to blowing can be made by simply turning the fan to face in the opposite direction. The well-designed out air flow ensures that the filter fans are also extremely quiet.
