Finder 7F.31.8.230.2055 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.8.230.2055 Outdoor Reverse-Flow Filter Fan?

The Finder 7F.31.8.230.2055 is a compact and reliable 230 V AC reverse-flow filter fan designed for ventilation and thermal management in outdoor industrial electrical enclosures. As part of the Finder 7F Series, this size 2 filter fan is engineered to extract warm air from electrical cabinets while helping protect sensitive components against dust and moisture.

Unlike conventional intake filter fans, the Finder 7F.31 reverse-flow configuration directs air outwards from the enclosure, helping remove accumulated heat generated by electrical and electronic equipment. Its IP54 ingress protection, durable plastic housing and replaceable filter mat make it suitable for industrial installations where dependable ventilation and environmental protection are important.

Operating from a 230 V AC, 50/60 Hz supply, the 7F.31.8.230.2055 delivers 55 m³/h free airflow at 50 Hz and 63 m³/h at 60 Hz. Its compact 155 × 155 mm external face, ball-bearing axial fan motor and shallow installation depth make it particularly suitable for smaller outdoor electrical cabinets, automation panels and industrial control enclosures.

Reliable Reverse-Flow Ventilation for Outdoor Electrical Cabinets

Electrical cabinets containing programmable logic controllers, power supplies, contactors, variable frequency drives and other electronic components generate heat during operation. Without adequate ventilation, internal temperatures can increase and affect equipment reliability, operating efficiency and service life. The Finder 7F.31.8.230.2055 helps address these challenges by actively extracting warm air from the enclosure, supporting controlled heat removal and more stable internal temperatures.

The Finder 7F.31 reverse-flow system differs from conventional intake filter fans by directing airflow out of the cabinet. When combined with appropriately positioned filtered air inlets, this arrangement allows cooler ambient air to replace the extracted warm air. The resulting airflow helps reduce heat accumulation around electrical components while the filtration system assists in limiting the entry of airborne contaminants.

Designed for outdoor electrical installations, the 7F.31.8.230.2055 combines IP54 environmental protection, IK08 impact resistance and a flame-retardant housing with a durable ball-bearing fan motor. Its compact mounting dimensions, push-in electrical terminals and easily replaceable filter mat simplify installation and maintenance. Correct airflow sizing, suitable inlet filtration and regular inspection help maintain reliable ventilation performance throughout the equipment's operating life.
