Why Choose the Pfannenberg PF 22.000 EMC 24 V DC Filterfan?
The Pfannenberg PF 22.000 EMC, article number 11822801055, is a fourth-generation EMC Filterfan designed for reliable thermal management in electrical and electronic enclosures. This installation-size 2 version operates from 24 V DC and delivers an unimpeded airflow of 61 m³/h, providing effective forced ventilation for control cabinets with moderate heat loads.
Designed specifically for applications where electromagnetic compatibility (EMC) is important, the PF 22.000 EMC incorporates a screened design with improved contact springs that provide secure electrical contact with the enclosure wall. This helps maintain the shielding concept of EMC-sensitive cabinets while still allowing filtered cooling air to enter the enclosure.
The filter fan has compact external dimensions of 145 × 145 mm and provides IP54 / NEMA Type 12 protection with its standard G4 filter. Tool-less mounting and tool-less filter-mat replacement simplify installation and routine servicing, while its broad -40 to +55 °C operating range supports demanding industrial environments.

Effective EMC Enclosure Thermal Management
EMC-sensitive electrical cabinets require ventilation components that can remove excess heat without unnecessarily compromising the enclosure's electromagnetic shielding concept. The PF 22.000 EMC addresses this requirement through its screened construction and improved contact springs, which establish secure contact with the conductive enclosure surface.
The 24 V DC version combines this EMC functionality with a 61 m³/h free-air performance, low 5 W power consumption and a ball-bearing fan designed for long-term continuous operation. When paired with a suitable Pfannenberg exhaust filter, it provides a complete filtered airflow path for industrial enclosure cooling.
Typical Applications
- EMC-shielded electrical control cabinets.
- Industrial automation and PLC enclosures.
- Variable-speed drive and motor-control cabinets.
- Machine-control systems.
- Electronic instrumentation enclosures.
- Industrial communication and data equipment.
- Production machinery requiring 24 V DC enclosure ventilation.
- Electrical cabinets requiring filtered forced-air cooling and EMC continuity.
