Why Choose the Finder 7F.21.9.024.3100.0 Reverse Flow Filter Fan?
The Finder 7F.21.9.024.3100.0 is a compact and reliable 24 V DC reverse flow filter fan designed for effective ventilation and thermal management of industrial electrical cabinets, control panels and automation enclosures. Based on the Finder 7F.21.9.024.3100 model from the 7F Series, this fan is designed to extract warm air from electrical enclosures, helping reduce heat accumulation around sensitive electrical and electronic components.
Featuring a reverse airflow configuration, the 7F.21 Series provides forced-air exhaust ventilation rather than conventional intake airflow. Its integrated filtration system helps maintain filtered airflow through the ventilation assembly, while the compact plastic housing and replaceable filter mat simplify installation and routine maintenance. The fan is designed for indoor electrical enclosure applications and offers IP54 protection when correctly installed.
With a 24 V DC supply, a nominal free-flow air volume of 100 m³/h and a 7 W rated power consumption, the Finder 7F.21.9.024.3100.0 is suitable for electrical cabinets containing PLCs, power supplies, motor controllers and industrial automation equipment. Its Size 3 mounting format provides a practical solution for forced-air ventilation in industrial control panels.

Reliable Thermal Management for Industrial Electrical Enclosures
Industrial electrical cabinets frequently contain components that generate heat during operation, including power supplies, PLCs, motor drives, contactors and other automation equipment. Without adequate ventilation, excessive internal temperatures can affect equipment reliability, reduce component service life and interrupt production processes. The Finder 7F.21.9.024.3100.0 reverse flow filter fan helps manage these conditions by extracting warm air from the enclosure and supporting continuous airflow through the cabinet.
The Finder 7F.21 Series is designed for reverse flow operation, making it particularly suitable for installations requiring exhaust ventilation rather than conventional filtered air intake. Its compact construction, low-noise operation and replaceable filtration system support practical integration into industrial control cabinets. When combined with a suitably sized replacement-air opening or filter arrangement, the fan helps maintain effective enclosure ventilation and dependable thermal management.
Typical Applications
- Industrial electrical cabinets and control panels.
- PLC and industrial automation enclosures.
- Electrical distribution and switchgear cabinets.
- Motor control panels and variable frequency drive enclosures.
- 24 V DC industrial control systems.
- Machine-building and OEM electrical equipment.
- Industrial power supply and electronic equipment cabinets.
- Packaging and manufacturing machinery control panels.
- Material handling and conveyor automation systems.
- Electrical enclosure ventilation and thermal management installations.
