The Pfannenberg 11842803055 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 installation size 4 model combines effective thermal management, G4 filtration and secure EMC contact for cabinets containing sensitive automation, control and power electronic equipment.
Operating from a 24 V DC supply, the PF 42.500 EMC provides an unimpeded airflow of 145 m³/h, delivering effective ventilation for electrical cabinets containing heat-generating components. The filtered airflow helps dissipate excess heat while reducing the ingress of dust and airborne contaminants that can affect the reliability and service life of sensitive electrical and electronic equipment.
The 11842803055 combines an IP55 protection rating with UV-resistant RAL 7035 construction, making it particularly suitable for demanding industrial enclosure applications. With frontal dimensions of 252 × 252 mm and an overall depth of approximately 103 mm, the filter fan provides substantial cooling capacity in a practical panel-mounted format while retaining compatibility with installation size 4 cut-outs.
Filter fans such as the Pfannenberg PF 42.500 provide an efficient method of controlling temperatures inside electrical cabinets when ambient conditions permit forced-air ventilation. Filtered ambient air is moved through the enclosure to dissipate heat generated by variable frequency drives, PLCs, power supplies, relays and other electrical components, helping maintain suitable operating temperatures and dependable equipment performance.
The PF 42.500 EMC series is specifically designed for installations where electromagnetic compatibility is also important. Its EMC construction and contact springs provide secure contact with the enclosure wall, helping maintain shielding around the ventilation opening. The IP55 and UV-resistant configuration of the 11842803055 also provides enhanced environmental durability for demanding industrial applications.
