PF Series EMC Filterfans & Exhaust Filters

Protect your sensitive electronics from electromagnetic interference when cooling with Filterfans®. The use of a Filterfan® for thermal management requires an opening to be cut into the cabinet. These openings can allow electromagnetic radiation to pass in or out unhindered.

Pfannenberg’s EMC Filterfans® offer the widest range of protection against electromagnetic interference. We offer several combinations of EMC Filterfans® and exhaust filters for air flow rates from 17 to 560 CFM2.

To better protect the environment, our EMC Filterfans® and exhaust filters do not use metalized plastics, because these are difficult to recycle.

EMC – Electromagnetic Compatibility

In standards, electromagnetic compatibility, or ‘EMC’ for short, is defined as the ability of a component, device or system to function satisfactorily under the influence of electromagnetic fields in its surroundings, without influencing its surroundings, to which other electrical equipment also belongs, in an impermissible way. We guarantee that our EMC shielded Filterfans® provide protection against electromagnetic interference by ensuring continuity between the shielding part of the fan and the metal structure of the cabinet based on the attenuation characteristics below:

Attenuation at 30 MHz approx. 71 dB
Attenuation at 400 MHz approx. 57 dB
Measured in accordance with EN 50 147-1 (1996): absorber rooms, part 1, measurement of screening attenuation.


Superior Metal Shielding

Unequaled worldwide: contact surfaces without beryllium-copper seal!


No elaborate reworking of the cut-out

• No adhering of copper tape or similar aids
• No time-consuming scratching off of coatings in order to ensure a good contact
• Contact is made via the cut edge of the cut-out for the Filterfans® or exhaust filter
