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 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.
Typical Applications
- Industrial electrical control cabinets.
- Automation and PLC enclosures.
- Variable frequency drive and motor control panels.
- EMC-sensitive electrical installations.
- Industrial systems using 115 V AC auxiliary supplies.
- Power electronics and power supply cabinets.
- Machine control and production equipment.
- Switchgear and electrical distribution enclosures.
- OEM machinery requiring filtered forced-air cooling.
