Why Choose the Finder 7F.31.8.230.4250 Outdoor Reverse Flow Filter Fan?
The Finder 7F.31.8.230.4250 is a high-performance Size 4 outdoor reverse flow filter fan designed for forced-air ventilation and thermal management in industrial electrical cabinets, control panels and automation enclosures. Part of the Finder 7F Series, the 7F.31 range provides a reverse airflow configuration specifically intended for outdoor electrical enclosure applications.
Operating from a 230 V AC supply at 50/60 Hz, the fan delivers a nominal 250/295 m³/h free-air flow rate at 50/60 Hz. When used with a compatible exhaust filter, the rated airflow is approximately 195/228 m³/h, providing effective ventilation for cabinets containing heat-generating electrical and electronic equipment.
Featuring IP54 ingress protection, IK08 impact resistance, a replaceable filter mat and a durable enclosure-mounted design, the Finder 7F.31.8.230.4250 is suitable for demanding industrial installations. Its compact 255 × 255 mm front dimensions, ball-bearing motor and push-in electrical connections help simplify installation and routine maintenance.

Reliable Reverse Flow Cooling for Outdoor Electrical Cabinets
The Finder 7F.31.8.230.4250 is designed to support temperature control inside electrical enclosures containing heat-generating components such as PLCs, power supplies, contactors, motor controllers and variable frequency drives. Its motor-driven axial fan provides forced-air circulation to help remove accumulated heat and maintain suitable operating temperatures.
Unlike standard intake filter fans, the 7F.31 reverse flow configuration is designed to extract air from the enclosure. This enables engineers to establish alternative airflow paths, position ventilation openings according to cabinet layout and optimise heat removal from electrical equipment. At 50 Hz, the fan provides a nominal free-air capacity of 250 m³/h, increasing to 295 m³/h at 60 Hz.
The outdoor-oriented construction incorporates IP54 ingress protection and IK08 impact resistance to support installation in demanding environments. When paired with appropriately sized ventilation accessories, the fan helps provide a controlled airflow path through the cabinet. Actual cooling performance depends on the enclosure heat load, ambient conditions, airflow resistance and filter condition.
Typical Applications
- Outdoor industrial electrical control cabinets.
- PLC and industrial automation enclosures.
- Electrical distribution and switchgear cabinets.
