Finder 7F.31.8.230.4400.7 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.8.230.4400.7 Outdoor Reverse-Flow Filter Fan?

The Finder 7F.31.8.230.4400.7 is a high-capacity 230 V AC outdoor reverse-flow filter fan from the Finder 7F Series, designed to provide forced-air exhaust ventilation for industrial electrical cabinets, automation enclosures and outdoor control panels. This Size 4 filter fan delivers a nominal airflow capacity of 400 m³/h, helping remove heat generated by electrical and electronic equipment.

Unlike standard draw-in filter fans, the Finder 7F.31 reverse-flow configuration is designed to extract 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, variable speed drives and other industrial control components.

Featuring a RAL 7035 light grey housing, the Finder 7F.31.8.230.4400.7 is particularly suitable for installations where ventilation components need to match conventional light grey electrical enclosures. Its outdoor-oriented construction, integrated filter arrangement and replaceable filter media provide a practical solution for electrical panel builders, automation engineers and industrial maintenance teams.

High-Capacity Reverse-Flow Ventilation for Outdoor Automation Cabinets

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 solar exposure and changing ambient temperatures.

The Finder 7F.31.8.230.4400.7 uses a reverse-flow exhaust arrangement to remove heated air from the enclosure. Installing the fan in an appropriate exhaust position, together with a suitably sized filtered air inlet, helps establish an effective airflow path around heat-generating equipment.

With a nominal 400 m³/h airflow capacity, the fan provides substantial ventilation for industrial control cabinets. Actual installed airflow depends on filter resistance, inlet openings, enclosure layout and operating conditions. Engineers should therefore size the ventilation arrangement according to the cabinet's heat load rather than relying solely on the nominal airflow figure.

The RAL 7035 light grey finish makes this variant particularly suitable for installations where external ventilation components need to match standard industrial electrical enclosures. Its replaceable filter media also supports planned maintenance in environments where dust and airborne contaminants may accumulate.

Fan-assisted ventilation cannot cool an enclosure below the temperature of the incoming ambient air. Applications involving high external temperatures, substantial solar loading or restrictive environmental conditions may require supplementary cooling. Correct installation and regular filter inspection help maintain effective ventilation performance.
