The Finder 7F.21.8.230.5700.0 is a high-capacity reverse flow filter fan for industrial electrical cabinets and control panel enclosures, designed to extract warm air and provide effective thermal management for electrical and electronic equipment. As part of the Finder 7F Series of enclosure cooling and ventilation products, this fan is developed for electrical panel builders, industrial automation engineers and OEM machine manufacturers requiring dependable forced-air ventilation.
Featuring a reverse airflow configuration, the Finder 7F.21.8.230.5700.0 operates as an exhaust fan, removing warm air from electrical enclosures to help maintain suitable internal operating temperatures. Its integrated replaceable filter mat, robust plastic housing and practical snap-in mounting system make it suitable for demanding industrial applications where effective cooling, straightforward maintenance and reliable operation are essential.
With a nominal operating voltage of 230 V AC at 50/60 Hz and a free-flow air volume of 660 m³/h at 50 Hz and 700 m³/h at 60 Hz, the Finder 7F.21.8.230.5700.0 provides substantial ventilation capacity for larger electrical cabinets and automation enclosures. Its Size 5 configuration, IP54 protection rating and cabinet-mounted construction make it a practical choice for industrial enclosure cooling systems.
Industrial electrical cabinets frequently contain heat-generating components such as variable frequency drives, programmable logic controllers, power supplies, contactors and industrial automation equipment. Excessive internal temperatures can affect component performance, operational reliability and equipment service life. The Finder 7F.21.8.230.5700.0 reverse flow filter fan helps manage these conditions by extracting warm air from the enclosure and supporting effective forced-air ventilation.
Unlike conventional intake filter fans, the Finder 7F.21 reverse flow configuration is designed to move air from inside the electrical cabinet towards the external environment. With a maximum nominal free-flow air volume of 700 m³/h at 60 Hz, this model is particularly suitable for larger industrial control panels requiring substantial exhaust ventilation. When combined with appropriately sized filtered air inlets, the fan supports continuous air circulation and helps reduce heat accumulation around electrical equipment.
The integrated G3 synthetic fibre filter mat provides filtration at the ventilation opening and can be replaced during routine maintenance. Its progressive filtration structure helps capture airborne particles, while the IP54-rated assembly, when correctly installed, supports protection against harmful dust ingress and splashing water.
The Finder 7F Series is designed for convenient installation and servicing. Its snap-in mounting system reduces installation complexity, while the Size 5 housing provides high airflow capacity for demanding electrical enclosure applications. Actual ventilation performance depends on the enclosure design, airflow resistance, filter condition and operating frequency.

The Finder 7F.21.8.230.5700.0 is a reverse flow filter fan designed to extract warm air from industrial electrical cabinets, automation enclosures and control panels. It helps maintain suitable internal temperatures for electrical and electronic equipment.
The fan operates from a nominal 230 V AC supply at 50/60 Hz, making it suitable for industrial electrical installations with a compatible alternating current power source.
The fan provides a nominal free-flow air volume of 660 m³/h at 50 Hz and 700 m³/h at 60 Hz. With the specified exhaust filter installed, the corresponding airflow values are 550 m³/h and 600 m³/h. Actual installed airflow depends on the ventilation arrangement and system resistance.
Reverse flow means the fan is configured to extract air from the electrical enclosure rather than draw external air into it. This allows warm air to be expelled from the cabinet as part of a properly designed ventilation system.
The fan has an IP54 protection rating according to EN 60529 and a NEMA Type 12 classification when correctly installed, supporting protection against dust and specified environmental exposure in suitable indoor industrial applications.
Yes. The fan incorporates a replaceable G3 synthetic fibre filter mat with progressive filtration construction. The filter supports dust filtration and can be replaced during routine maintenance to help maintain ventilation performance.
The fan has approximate overall dimensions of 320 × 320 × 141.2 mm and requires a nominal 291 × 291 mm enclosure cut-out. Its Size 5 configuration is intended for installation into larger industrial electrical cabinet walls.
The Finder 7F.21.8.230.5700.0 has a rated power consumption of 106 W at 50 Hz and 120 W at 60 Hz, providing high-capacity forced-air ventilation for industrial electrical enclosures.
The .0 suffix identifies the black RAL 9004 colour variant in the Finder 7F ordering system. This provides a black housing option for industrial electrical cabinets and control panels.
The Finder 7F.21.8.230.5700.0 belongs to the indoor reverse flow filter fan range. Outdoor installations should use appropriately rated ventilation equipment designed for the expected environmental conditions.
Finder 7F Series filter fans provide dependable ventilation for electrical cabinets, industrial automation systems and machine control equipment. Combining high-capacity reverse airflow, a 230 V AC supply, replaceable filtration and IP54 protection, the Finder 7F.21.8.230.5700.0 offers a practical solution for panel builders, OEM manufacturers and maintenance engineers seeking effective thermal management in demanding industrial environments.
