Finder 7F.31.9.024.2055 – 7F Series Filter Fans – For outdoor use – Reverse flow

Why Choose the Finder 7F.31.9.024.2055 Outdoor Reverse Flow Filter Fan?

The Finder 7F.31.9.024.2055 is a compact 24 V DC outdoor reverse flow filter fan designed for ventilation and thermal management of industrial electrical cabinets, control panels and equipment enclosures. Part of the Finder 7F Series, this Size 2 exhaust fan helps remove accumulated warm air from electrical enclosures, supporting reliable operating conditions for sensitive electronic and automation components.

Featuring a reverse airflow configuration, the Finder 7F.31.9.024.2055 extracts air from the enclosure rather than operating as a conventional intake filter fan. Its outdoor-oriented construction combines IP54 ingress protection and IK08 mechanical impact resistance with a replaceable filter mat, making it suitable for demanding industrial installations where effective ventilation and convenient maintenance are important.

With a 24 V DC supply, 55 m³/h nominal free-flow airflow, 40 m³/h filtered airflow and 7 W rated power consumption, the Finder 7F.31.9.024.2055 offers an efficient exhaust ventilation solution for compact electrical cabinets. Its 155 × 155 mm front dimensions and 57.2 mm installation depth support integration into space-conscious industrial enclosure designs.

Reliable Exhaust Ventilation for Outdoor Electrical Enclosures

Industrial electrical cabinets often contain components that generate heat during normal operation, including PLCs, power supplies, communication modules, contactors and electronic control equipment. In outdoor installations, environmental temperatures and solar exposure can further increase internal enclosure temperatures. The Finder 7F.31.9.024.2055 reverse flow filter fan helps manage these conditions by actively extracting warm air, supporting continuous air exchange and reducing the risk of heat accumulation around sensitive equipment.

The Finder 7F.31 outdoor reverse flow range combines compact construction with practical environmental protection and straightforward maintenance. The Size 2 fan is particularly useful where enclosure space is limited, while its replaceable filter mat and ball-bearing construction support long-term ventilation requirements. For effective cooling, the fan should be installed with an appropriately sized replacement-air opening or intake filter, with airflow selected according to the enclosure heat load, ambient temperature and expected pressure losses.
