Why Choose the Finder 7F.31.9.024.3100 Outdoor Reverse Flow Filter Fan?
The Finder 7F.31.9.024.3100 is a 24 V DC outdoor reverse flow filter fan designed to provide effective exhaust ventilation and thermal management for industrial electrical cabinets, control panels and equipment enclosures. Part of the Finder 7F Series, this fan actively extracts warm air from electrical enclosures, helping maintain suitable operating conditions for heat-sensitive electrical and electronic components.
Featuring a reverse airflow configuration, the Finder 7F.31.9.024.3100 is designed to remove heated air rather than introduce air through a conventional intake fan. Its outdoor-rated construction provides IP54 ingress protection, IK08 mechanical impact resistance and NEMA Type 3R classification when correctly installed. A replaceable filter mat and convenient mounting arrangement help simplify routine maintenance.
Operating from a 24 V DC supply, the fan delivers 100 m³/h nominal unimpeded airflow and 75 m³/h filtered airflow with a rated input power of just 7 W. Its Size 3 mounting format, 209 × 209 mm front dimensions and ball-bearing construction make it a practical solution for industrial automation systems, outdoor electrical cabinets and machinery control enclosures requiring dependable exhaust ventilation.

Reliable Exhaust Ventilation for Outdoor Electrical Enclosures
Industrial electrical cabinets often contain heat-generating components such as PLCs, power supplies, variable frequency drives, contactors and electronic control equipment. In outdoor installations, elevated ambient temperatures and solar exposure can increase the thermal load inside the enclosure. The Finder 7F.31.9.024.3100 reverse flow filter fan helps manage these conditions by actively extracting warm air, supporting continuous air exchange and reducing heat accumulation around sensitive components.
The Finder 7F.31 outdoor reverse flow range combines weather-resistant construction with practical ventilation and maintenance features. Its IP54 ingress protection, IK08 impact resistance and NEMA Type 3R classification support installation in appropriately designed outdoor cabinets, while the replaceable filter mat helps simplify servicing. For effective cooling, the fan should be installed with a suitably sized replacement-air opening or intake filter, with airflow selected according to enclosure heat load, ambient temperature and system pressure losses.
Typical Applications
- Outdoor industrial electrical cabinets and control panels.
- PLC and industrial automation control enclosures.
- Electrical distribution and switchgear cabinets.
- Variable frequency drive and motor control enclosures.
- Industrial communication and networking cabinets.
- Electrical power supply and electronic equipment enclosures.
- Outdoor machinery and equipment control systems.
- Utility infrastructure and remote monitoring installations.
- OEM machine-building and automation equipment.
- Industrial enclosure exhaust ventilation and thermal management systems.
