The RUCK CPA 400 D42 F4 01 is a high-performance axial jet fan engineered for impulse ventilation and emergency smoke extraction in enclosed car parks and underground garages. Featuring a 400mm impeller with an optimized impeller and nozzle design, the fan delivers high thrust efficiency while maintaining low energy consumption.
This model is equipped with an IE3 efficiency motor with 2‑step speed control via a Dahlander circuit, allowing operation at two selectable speeds. This enables energy-efficient low-speed operation during normal ventilation and high-speed performance when increased airflow or smoke extraction is required.
The weight-optimized housing is constructed from durable AlMg3 aluminium and steel plate, ensuring long-term reliability while simplifying installation. Certified to F400, the CPA 400 D42 F4 01 is approved for smoke extraction at temperatures up to 400°C for 2 hours, while also supporting continuous operation with conveyed air temperatures up to 60°C. Height adjustment during assembly provides additional flexibility, making this jet fan well suited to a wide range of car park layouts and smoke control system designs.
