Why Choose the Pfannenberg PF22.000 24 V DC IP55 UV EMC Filterfan?
The Pfannenberg PF22.000 EMC 11822803055 is a 4th Generation εCOOL Filterfan designed for reliable thermal management of electrical and electronic enclosures. This exact version operates from 24 V DC and delivers an unimpeded airflow of 56 m³/h, providing effective forced-air cooling for control cabinets, automation panels and industrial electronics.
Designed for demanding enclosure applications, the 11822803055 version provides IP55 protection with a fluted G4 filter and NEMA Type 12 performance. The IP55 version is also UV resistant, making it suitable for applications where the filter fan may be exposed to increased environmental stresses.
As an EMC Filterfan, the PF22.000 EMC incorporates a screen grid with improved contact springs to provide secure electrical contact with the enclosure wall. Tool-free mounting and filter replacement simplify installation and maintenance, while compatibility with installation size 2 cut-outs from both the 3rd and 4th generations helps streamline retrofit applications.

Efficient EMC-Compatible Enclosure Cooling
Forced-air enclosure cooling helps remove heat generated by drives, power supplies, controllers and other electronic components when the surrounding ambient air is sufficiently cool. The PF22.000 EMC draws filtered ambient air through the enclosure, helping maintain more stable internal temperatures while reducing the ingress of airborne contamination.
For EMC-sensitive installations, the PF22.000 EMC incorporates improved contact springs on its screen grid to ensure secure contact with the enclosure wall. Combined with IP55 protection, 56 m³/h airflow, G4 filtration and UV resistance, the 11822803055 provides a practical thermal-management solution for demanding industrial control systems.
Typical Applications
- Industrial electrical control cabinets.
- PLC and automation enclosures.
- Variable-speed drive and motor-control panels.
- Machine control systems.
- EMC-sensitive electrical installations.
- Industrial electronics and instrumentation cabinets.
- Enclosures requiring IP55 filtered forced-air cooling.
