  ATTENUATION LEVELS OF EMC FILTER FANS

KOOLTRONIC Advantage Series Filter Fans are also available with shielding against electromagnetic interference (EMI).
This EMC Filter Fan version is achieved by metallizing the plastic parts, which function as a shield, i.e., they are connected to an EMI-shielding wire mesh. To guarantee the continuity between the shielding part of the fan and the metal structure of the cabinet, a gasket is used, which also protects from dust.

In order to choose the correct dimensions of the filter fan to be integrated into your cabinet, the project designer must also take into consideration the frequency band that has to be dampened.

Important note: Isolation materials, such as varnishes or coatings, should not be used on the contact zone between gasket and cabinet.
