Ventilation fan

axialfor aircraft cabinfloor-mounted

The Diehl Aviation portfolio comprises electrically driven variable High Speed Fans with a wide frequency range of power supply that recirculate air from the cabin to the aircraft’s air-conditioning system. Our devices can reach a rotational speed up to 40.000 rpm with a power consumption of 15 kVA and a volume flow of 1.100 l/s. Most are configured as an axial flow in-line fan with a 4-pole permanent magnet synchronous brushless motor. The embedded software controls the fan speed, communicates with the aircraft ECS system via CAN Bus, and provides health and failure monitoring features.
