Why Choose the Pfannenberg PF 22.000 EMC 11822851055 Filterfan?
The Pfannenberg PF 22.000 EMC 11822851055 is a compact 12 V DC EMC Filterfan designed to provide filtered forced-air cooling for electrical enclosures, control cabinets and industrial automation equipment. Part of Pfannenberg's 4th Generation Filterfan range, it combines effective enclosure ventilation with an EMC-compatible design for applications where electromagnetic shielding performance must be maintained.
This installation size 2 Filterfan has an IP54 protection rating and delivers an unimpeded airflow of 61 m³/h. When used together with the corresponding exhaust filter, the rated airflow is 44 m³/h. Its integrated G4 filter mat helps prevent airborne contamination from entering the enclosure while allowing heat generated by electrical and electronic components to be removed efficiently.
Operating from a 12 V DC supply, the PF 22.000 EMC uses only 5 W of power and features a DC ball-bearing fan for dependable continuous-duty operation. With compact dimensions of approximately 145 × 145 × 69 mm and tool-less installation features, it is well suited to modern control-panel and machine-building applications.

Reliable Filtered Cooling for EMC Enclosures
Filterfans provide a cost-effective method of removing excess heat from electrical cabinets when the ambient air temperature is suitable for forced-air cooling. The Pfannenberg PF 22.000 EMC draws filtered ambient air into the enclosure, helping maintain acceptable operating temperatures for drives, power supplies, PLCs and other heat-generating electrical components.
The EMC version incorporates contact springs that provide secure electrical contact with the enclosure wall and support the shielding requirements of EMC-sensitive installations. Its compact construction, tool-less mounting system and replaceable filter mat make it particularly practical for industrial panel builders and machine manufacturers.
Typical Applications
- Electrical control cabinets and enclosures.
- EMC-sensitive control and automation systems.
- PLC and industrial electronics enclosures.
- Machine-building electrical panels.
- Industrial power supply and drive cabinets.
- Factory automation and production equipment.
