The Pfannenberg 11842151055 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 control cabinets containing sensitive automation, control and power electronic equipment.
Operating from a 115 V AC, 50/60 Hz supply, the PF 42.500 EMC provides 125 m³/h unimpeded airflow at 50 Hz and 138 m³/h at 60 Hz. When combined with a matching exhaust filter, airflow is approximately 93 / 102 m³/h at 50 / 60 Hz. This provides effective ventilation for electrical cabinets containing heat-generating components while the 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 11842151055 provides substantial cooling capacity in a practical panel-mounted format. Its IP54 and NEMA Type 12 protection, EMC screened construction and improved contact springs make it particularly suitable for industrial installations where dependable thermal management and electromagnetic compatibility are both important.
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 screened construction and improved contact springs provide secure contact with the metallic enclosure wall, helping maintain EMC shielding around the ventilation opening while the G4 filter provides effective protection against airborne contamination.
