DC Axial Fans — selection guide
DC Axial Fans: 22 models, impellers Ø200–300 mm, maximum airflow 979–2,524 m³/h, static pressure to 319 Pa, DC motors, across 3 series. 22 of them carry a measured P-Q curve and 22 a dimensional drawing.
LWAD3G DC axial fans cover Ø200, 250 and 300 mm for equipment running on a DC bus: 24 V and 48 V versions for telecom and battery-powered units, and 310 V versions for inverter and heat-pump designs that rectify the mains once and drive the fan from the DC link. Airflow 979–2,524 m³/h at 185–319 Pa, 55–165 W, IP44 or IP42, metal or PA66 impellers, with PWM control and feedback.
How to select from this range
- Match the fan voltage to the bus: 24 / 48 V for telecom and battery systems, 310 V for DC-link designs.
- Use PWM control and the tacho output to integrate with the equipment controller.
- Check the IP rating — IP44 for outdoor units, IP42 for indoor cabinets.
Where these fans are used
- Telecom outdoor cabinets
- Battery energy-storage containers
- Inverter heat pumps with DC-link fans
Every figure above is measured on our own test rigs per AMCA 210 / ISO 5801 methods — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.
FAQ — DC Axial Fans
Why is there a 310 V DC axial fan?
Inverter-driven heat pumps and chillers already have a rectified DC link at about 310 V; a fan running directly from it saves a separate supply and a mains-side EC stage. 18 of the 22 models in this line are 310 V.
Are 12 V axial fans of this size available?
The Ø200–300 mm DC line is 24 / 48 / 310 V; 12 V is available in the compact cooling-fan frames up to 200 mm.
