Finder 7F.31.8.230.5700 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.8.230.5700 Outdoor Reverse Flow Filter Fan?

The Finder 7F.31.8.230.5700 is a high-capacity outdoor reverse flow filter fan designed to extract warm air from industrial electrical cabinets, automation panels and equipment enclosures. Part of the Finder 7F Series, this Size 5 fan provides forced-air exhaust ventilation for installations where effective thermal management, environmental protection and dependable operation are essential.

Featuring a reverse airflow configuration, the Finder 7F.31.8.230.5700 removes heated air from inside the enclosure rather than drawing ambient air into it. When combined with a suitably sized filtered air inlet, it helps establish a controlled ventilation path around heat-generating components such as variable frequency drives, power supplies, programmable logic controllers and industrial control equipment.

Operating from a nominal 230 V AC supply at 50/60 Hz, this fan delivers a free-flow air volume of 660 m³/h at 50 Hz and 700 m³/h at 60 Hz. Its IP54 ingress protection, IK08 impact resistance and outdoor-oriented Type 3R construction make it particularly suitable for demanding industrial enclosure ventilation applications.

High-Capacity Exhaust Ventilation for Outdoor Electrical Cabinets

Industrial electrical cabinets often contain equipment that generates significant heat during normal operation. Variable frequency drives, motor controllers, power conversion equipment and automation systems can increase internal temperatures, particularly in densely populated panels or outdoor installations exposed to solar heating. The Finder 7F.31.8.230.5700 helps manage these conditions by actively extracting warm air from the enclosure.

The reverse flow design moves air from the inside of the electrical cabinet towards the external environment. When installed with an appropriately positioned filtered intake opening, the fan encourages cooler ambient air to enter the enclosure while warmer air is expelled. This supports effective air circulation and helps reduce localised heat accumulation around sensitive electrical components.

With a nominal free-flow capacity of 660 m³/h at 50 Hz and 700 m³/h at 60 Hz, the Finder 7F.31.8.230.5700 is particularly suitable for larger industrial control cabinets. When used with the specified exhaust filter arrangement, the corresponding airflow figures are 550 m³/h and 600 m³/h. Actual installed performance depends on enclosure geometry, airflow resistance and filter condition.

The fan's IP54 protection rating helps limit harmful dust ingress and provides resistance to splashing water. Its IK08 impact resistance and outdoor-oriented Type 3R construction provide additional suitability for demanding industrial installations. Correct fitting and suitable enclosure design are essential for maintaining the specified environmental protection.

The hinged cover and replaceable filter mat allow convenient access during scheduled maintenance. Regular filter inspection and replacement help maintain ventilation performance and prevent accumulated contamination from restricting airflow. The ball-bearing fan motor supports dependable operation in industrial ventilation applications.

For effective thermal management, ventilation capacity should be selected according to the heat dissipated by installed equipment, the maximum ambient temperature and the permissible internal temperature rise. Filter fans use ambient air and cannot cool an enclosure below the temperature of the incoming air. Where ambient temperatures exceed the required cabinet temperature, an alternative cooling method may be necessary.
