The Finder 7F.31.8.230.5550 is a high-capacity 230 V AC outdoor reverse-flow filter fan from the Finder 7F Series, designed to extract warm air from industrial electrical cabinets, automation enclosures and outdoor control panels. This Size 5 filter fan provides 550 m³/h free-air flow at 50 Hz and 605 m³/h at 60 Hz, supporting effective thermal management in enclosures containing heat-generating electrical equipment.
Unlike standard draw-in filter fans, the Finder 7F.31 reverse-flow configuration expels heated air from the enclosure. When paired with a suitably positioned filtered air inlet, it helps establish a controlled ventilation path through the cabinet, supporting heat dissipation around PLCs, variable speed drives, motor starters, power supplies and other electronic components.
Featuring IP54 ingress protection, IK08 impact resistance, a 320 × 320 mm external face and a 131.5 mm installation depth, the Finder 7F.31.8.230.5550 combines high airflow capacity with practical enclosure integration. Its ball-bearing fan construction, replaceable filter mat and outdoor-oriented design make it suitable for demanding industrial applications.
Industrial electrical cabinets can experience elevated internal temperatures due to heat generated by variable speed drives, motor starters, PLCs, power supplies and other electronic components. Outdoor installations may experience additional thermal loading from direct sunlight and changing ambient conditions.
The Finder 7F.31.8.230.5550 uses a reverse-flow exhaust arrangement to remove heated air from the enclosure. Installing the fan towards the upper section of a cabinet, together with a suitably sized filtered air inlet, can help establish an effective ventilation path around heat-generating electrical equipment.
With 550 m³/h free-air flow at 50 Hz and 605 m³/h at 60 Hz, the fan provides substantial ventilation capacity for larger industrial cabinets. Its listed 440 m³/h filtered airflow demonstrates the effect of filtration on available airflow. Actual installed performance depends on enclosure layout, filter resistance, ventilation openings and operating conditions.
The IP54 protection rating and IK08 impact resistance support use in appropriately designed outdoor electrical installations. The ball-bearing fan construction provides a practical solution for industrial operation, while the replaceable filter mat allows maintenance engineers to service the ventilation system when required.
Fan-assisted ventilation cannot cool an enclosure below the temperature of the incoming ambient air. Engineers should therefore assess cabinet heat load, ambient temperature, environmental exposure and required airflow before selecting the ventilation arrangement. Regular inspection of the filter mat and ventilation openings helps maintain effective cooling performance.
