Why Choose the Pfannenberg PF 32.000 EMC 11832101055 Filterfan?
The Pfannenberg PF 32.000 EMC 11832101055 is a fourth-generation EMC filter fan designed to provide reliable filtered ventilation while helping maintain electromagnetic shielding in industrial control cabinets and electrical enclosures. Part of the Pfannenberg Filterfans 4.0 range, this installation size 3 unit combines efficient enclosure cooling with an integrated metal screen and improved contact springs for secure electrical contact with the cabinet wall.
Unlike conventional plastic filter fans, the PF 32.000 EMC is specifically engineered for installations where the enclosure's electromagnetic compatibility must be maintained around the ventilation opening. Its stainless-steel EMC screen helps reduce the impact of the cabinet cut-out on electromagnetic shielding, making the unit particularly suitable for automation, electronics and industrial control applications containing sensitive equipment.
This 230 V AC, 50/60 Hz version provides an unimpeded airflow of 98 m³/h at 50 Hz and 108 m³/h at 60 Hz. It features IP54 and NEMA Type 12 protection, a G4 filter mat and a compact 202 × 202 mm face size, providing an effective solution for forced-air cooling of industrial enclosures.

Effective EMC Enclosure Cooling and Ventilation
Industrial electrical cabinets rely on controlled airflow to remove heat generated by drives, power supplies, PLCs and other electronic equipment. The PF 32.000 EMC draws cooler ambient air through its filter mat and into the enclosure, creating forced ventilation that helps maintain suitable internal operating temperatures while limiting contamination from airborne particles.
The EMC version also addresses the electromagnetic shielding weakness normally introduced when a ventilation opening is cut into a metal enclosure. Its conductive stainless-steel screen and contact-spring arrangement establish contact with the enclosure wall, helping preserve electromagnetic protection while still allowing the airflow required for thermal management.
Typical Applications
- Industrial electrical and electronic control cabinets.
- PLC and automation enclosures requiring EMC protection.
- Variable-speed drive and motor-control panels.
- Machine-building and OEM control systems.
- Industrial communications and instrumentation cabinets.
- Manufacturing and process-control equipment.
