Reliable High-Capacity Cooling for Industrial Electrical Enclosures

Industrial electrical cabinets frequently contain heat-generating components such as variable frequency drives, programmable logic controllers, power supplies, contactors and industrial automation equipment. Excessive internal temperatures can affect component performance, operational reliability and equipment service life. The Finder 7F.21.8.230.5700.0 reverse flow filter fan helps manage these conditions by extracting warm air from the enclosure and supporting effective forced-air ventilation.

Unlike conventional intake filter fans, the Finder 7F.21 reverse flow configuration is designed to move air from inside the electrical cabinet towards the external environment. With a maximum nominal free-flow air volume of 700 m³/h at 60 Hz, this model is particularly suitable for larger industrial control panels requiring substantial exhaust ventilation. When combined with appropriately sized filtered air inlets, the fan supports continuous air circulation and helps reduce heat accumulation around electrical equipment.

The integrated G3 synthetic fibre filter mat provides filtration at the ventilation opening and can be replaced during routine maintenance. Its progressive filtration structure helps capture airborne particles, while the IP54-rated assembly, when correctly installed, supports protection against harmful dust ingress and splashing water.

The Finder 7F Series is designed for convenient installation and servicing. Its snap-in mounting system reduces installation complexity, while the Size 5 housing provides high airflow capacity for demanding electrical enclosure applications. Actual ventilation performance depends on the enclosure design, airflow resistance, filter condition and operating frequency.

Typical Applications

  • Large industrial electrical control cabinets and distribution panels.
  • PLC control panels and industrial automation enclosures.
  • Variable frequency drive and motor control cabinets.
  • Industrial switchgear and electrical distribution systems.
