Variable pitch control contrafan with movable wings

Different from inverter control, an overwhelming operating range! An environmentally friendly fan that does not generate harmonics.

The "Variable Pitch Control Contrafan" is an environmentally friendly fan that contributes to energy savings while also reducing the emission of CO2 gases, which are a factor in global warming. By adopting a variable pitch mechanism and a low starting current, high-efficiency electric motor (triple squirrel cage motor), it achieves high-efficiency operation, significantly reducing power consumption during operation. It comes standard with splitter-type silencers at the intake and exhaust ports, which have a large sound-absorbing area and high noise reduction effect, helping to suppress fan noise and provide a good working environment. 【Features】 ■ Energy-saving, low environmental impact ■ Dust sensor automatic control ■ Low noise ■ No harmonic generation ■ Three operating modes *For more details, please refer to the PDF materials or feel free to contact us.
