Reliable Thermal and EMC Protection for Industrial Enclosures
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.
Typical Applications
- Industrial electrical control cabinets.
- Automation and PLC enclosures.
- Variable frequency drive and motor control panels.
