High-Capacity 24 V DC Cooling for Outdoor Electrical Cabinets
The Finder 7F.30.9.024.4250 helps control temperatures inside electrical enclosures containing heat-generating equipment such as PLCs, power supplies, contactors, motor controllers and variable frequency drives. Its motor-driven axial fan introduces ambient air through the filter assembly, supporting continuous ventilation and the removal of accumulated heat.
With a nominal free-air capacity of 250 m³/h, the fan delivers approximately 195 m³/h when paired with a compatible exhaust filter under the manufacturer's stated test conditions. Actual airflow depends on cabinet resistance, filter condition and installation arrangement. The fan should be selected according to the enclosure heat load, ambient temperature and required ventilation performance.
The 7F.30 outdoor design incorporates protective features for demanding environments, including IP54 ingress protection, IK08 impact resistance and a NEMA Type 3R classification. Its replaceable synthetic fibre filter mat, ball-bearing fan motor and push-in electrical connections help simplify servicing while supporting dependable enclosure ventilation.
