Pfannenberg 11842801055 PF42.500 24VDC IP54 EMC 4th Gen Filterfan 156m3/h

Why Choose the Pfannenberg 11842801055 PF 42.500 EMC Filterfan?

The Pfannenberg 11842801055 PF 42.500 EMC is a high-performance 4th Generation EMC filter fan designed to provide reliable forced-air cooling for industrial electrical enclosures while helping maintain electromagnetic shielding. Part of the Pfannenberg PF 42.500 EMC range, this model combines efficient thermal management, G4 filtration and EMC-tested construction for control cabinets containing sensitive automation, control and power electronic equipment.

Operating from a 24 V DC supply, the PF 42.500 EMC delivers 125 m³/h unimpeded airflow and approximately 93 m³/h airflow when combined with a matching exhaust filter. With a power consumption of only 4.7 W, the filter fan provides an energy-efficient method of removing heat from electrical cabinets while its G4 filter helps reduce the ingress of dust and airborne contaminants.

With frontal dimensions of 252 × 252 mm and an overall depth of approximately 103 mm, the 11842801055 provides substantial cooling performance in a practical panel-mounted format. Its IP54 protection rating, EMC screening and tool-free 4-corner mounting system make it particularly suitable for industrial installations where dependable enclosure cooling and electromagnetic compatibility are both important.

Reliable Thermal and EMC Protection for Industrial Enclosures

Filter fans such as the Pfannenberg PF 42.500 provide an efficient and economical method of controlling temperatures inside electrical cabinets when the ambient temperature is below the required internal enclosure temperature. Filtered ambient air is moved through the cabinet to dissipate heat generated by variable frequency drives, PLCs, power supplies, relays and other electrical components, helping maintain reliable operating conditions.

The PF 42.500 EMC is specifically designed for installations where electromagnetic compatibility is also important. Its metal screening securely closes the shielding interruption created by the enclosure installation cut-out, helping attenuate electromagnetic radiation entering or leaving the cabinet while maintaining effective cooling airflow. The 4th Generation tool-free mounting and filter access system also helps minimise installation and servicing time.
