Why Choose the Finder 7F.31.8.230.4400 Outdoor Reverse Flow Filter Fan?
The Finder 7F.31.8.230.4400 is a high-capacity Size 4 outdoor reverse flow filter fan designed for effective ventilation and temperature management in industrial electrical cabinets, control panels and automation enclosures. Part of the Finder 7F Series, this model combines powered air extraction with a protective filter assembly to support reliable operation of heat-sensitive electrical equipment.
Operating from a 230 V AC supply at 50/60 Hz, the fan delivers a nominal free-air flow rate of 400 m³/h at 50 Hz and 445 m³/h at 60 Hz. Its reverse airflow configuration is designed to extract warm air from electrical enclosures, making it particularly useful where conventional intake ventilation arrangements are unsuitable.
With IP54 ingress protection, IK08 mechanical impact resistance, a durable grey housing and a replaceable filter mat, the Finder 7F.31.8.230.4400 is designed for demanding outdoor cabinet installations. Its 255 × 255 mm front dimensions, ball-bearing axial fan and push-in electrical terminals support convenient installation and servicing.

High-Capacity Reverse Flow Cooling for Outdoor Electrical Cabinets
The Finder 7F.31.8.230.4400 is designed to help control temperatures in electrical enclosures containing heat-generating equipment such as PLCs, power supplies, contactors, motor controllers and variable frequency drives. Its high-capacity axial fan moves warm air out of the enclosure, supporting heat dissipation and helping maintain suitable operating conditions.
The 7F.31 reverse flow configuration differs from the standard 7F.30 intake arrangement by reversing the airflow direction. This allows the fan to operate as an extraction unit and provides additional flexibility when designing cabinet ventilation paths. The fan offers a nominal 400 m³/h free-air flow rate at 50 Hz, increasing to 445 m³/h at 60 Hz.
Its outdoor-oriented construction includes IP54 protection and IK08 impact resistance, while the replaceable filter mat supports routine maintenance. Actual airflow through an installed enclosure depends on filter condition, ventilation openings, internal resistance and the overall cabinet design.
Typical Applications
- Outdoor industrial electrical control cabinets.
- PLC and industrial automation enclosures.
- Electrical distribution and switchgear cabinets.
- Variable frequency drive and motor control panels.
- Renewable energy and power conversion equipment enclosures.
- Telecommunications and outdoor infrastructure cabinets.
- Industrial machinery and manufacturing equipment.
- Process control and instrumentation installations.
- Power supply and electronic equipment cabinets.
- OEM electrical enclosure ventilation and thermal management systems.
