Finder 7F.31.8.120.4400 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.8.120.4400 Outdoor Reverse-Flow Filter Fan?

The Finder 7F.31.8.120.4400 is a high-capacity 120 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. With an unimpeded airflow capacity of 400 m³/h and a filtered airflow rating of 300 m³/h, this unit provides effective forced-air ventilation for heat-generating electrical equipment.

Unlike conventional draw-in filter fans, the Finder 7F.31 reverse-flow configuration is designed to expel warm air from the enclosure. When combined with a suitably positioned filtered air inlet, it helps establish a controlled ventilation path through the cabinet, supporting heat dissipation around PLCs, motor starters, power supplies and other electronic components.

Featuring IP54 ingress protection, IK08 impact resistance, a NEMA Type 3R classification and a dark grey RAL 7000 housing, the Finder 7F.31.8.120.4400 is suitable for appropriately designed indoor and outdoor industrial installations. Its replaceable filter mat, snap-in mounting arrangement and compact enclosure profile help simplify installation and maintenance.

Reverse-Flow Ventilation for Outdoor Electrical Cabinets and Automation Systems

Industrial electrical cabinets can experience elevated internal temperatures due to heat generated by power supplies, variable speed drives, motor starters, PLCs and other electronic components. Outdoor installations may experience additional thermal loading from solar exposure and changing ambient temperatures.

The Finder 7F.31.8.120.4400 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 suitable filtered air inlet, can help create an effective ventilation path that encourages cooler ambient air to pass around heat-generating equipment.

With 400 m³/h unimpeded airflow and 300 m³/h filtered airflow, the unit is suited to applications requiring substantial air movement. Actual installed airflow will depend on the enclosure layout, filter resistance, inlet openings and environmental conditions.

The IP54, IK08 and NEMA Type 3R classifications support use in appropriately designed industrial installations, including outdoor electrical cabinets. The dark grey RAL 7000 housing provides a suitable finish for machinery and control enclosures, while the replaceable filter mat allows routine servicing without unnecessarily disturbing internal electrical components.

Fan-assisted ventilation cannot reduce cabinet temperature below the temperature of the incoming ambient air. Engineers should therefore assess the enclosure heat load, outdoor exposure, airflow requirements and manufacturer's installation guidance before selecting the ventilation arrangement.
