Finder 7F.31.8.230.3100 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.8.230.3100 Outdoor Reverse-Flow Filter Fan?

The Finder 7F.31.8.230.3100 is a reliable 230 V AC reverse-flow electrical enclosure filter fan designed for effective ventilation and thermal management in outdoor industrial electrical cabinets. As part of the Finder 7F Series, this size 3 filter fan provides controlled air extraction to help remove excess heat generated by electrical and electronic components in industrial automation and power distribution systems.

Unlike conventional intake filter fans, the Finder 7F.31 reverse-flow configuration extracts warm air from inside the electrical enclosure, helping maintain suitable operating temperatures for sensitive equipment. The fan provides 100 m³/h nominal unimpeded airflow and 85.5 m³/h filtered airflow, making it suitable for medium-sized electrical cabinets requiring dependable heat extraction and environmental protection.

Operating from a 230 V AC, 50/60 Hz supply, the 7F.31.8.230.3100 combines a durable ball-bearing axial fan motor, IP54 ingress protection and a replaceable filter mat. Its compact 209 × 209 mm external face, 71.2 mm installation depth and convenient electrical connections simplify integration into outdoor control panels, industrial machinery cabinets and electrical distribution enclosures.

Reliable Reverse-Flow Ventilation for Industrial Electrical Enclosures

Industrial electrical cabinets containing programmable logic controllers, variable frequency drives, contactors, power supplies and other electronic equipment generate heat during normal operation. Excessive internal temperatures can reduce equipment reliability, accelerate component ageing and increase the likelihood of thermal faults. The Finder 7F.31.8.230.3100 helps address these challenges by extracting warm air from the enclosure, supporting more stable operating temperatures and effective heat dissipation.

The Finder 7F.31 reverse-flow ventilation system directs air outwards from the electrical cabinet rather than introducing air through an intake fan. When combined with appropriately positioned filtered air inlets, this arrangement encourages cooler ambient air to enter the enclosure while warmer air is expelled. The resulting circulation helps reduce heat accumulation around sensitive electrical components and supports dependable operation of industrial automation equipment.

Designed for outdoor industrial installations, the 7F.31.8.230.3100 combines IP54 environmental protection, IK08 impact resistance and a flame-retardant housing with a durable ball-bearing motor. Its compact dimensions, push-in electrical terminals and replaceable filter mat simplify installation and maintenance. Correct airflow sizing, suitable inlet filtration and regular filter inspection help preserve cooling performance throughout the equipment's operating life.
