DC Backward Curved Centrifugal

Product description:
DC centrifugal fans with backward-curved blades and covers a diameter range of models from φ133 to φ400, with maximum air volume up to 3,400 m3/h and maximum static pressure up to 600 Pa comprehensive ranges for every application. This external rotor fan series has a compact structure, operates reliably and is both energy saving and efficient. 100% speed control via analog or serial interface. Quiet operation with flow control and sophisticated DC motor commutation. Start-up made easy by perfectly coordinated components: Control system/motor/fanIt is designed with low noise, a long service life, and is easy to install. This series of axial fans has EC and AC available, Available input power sources for DC series are 12VDC, 24VDC, 48VDC and any VDC; DC motors make the fans more efficient, it is easier to control the fan and flexibly meet customers’ control requirements. DC motors come with a variety of control solutions and protection functions - to achieve intelligent control, energy savings and environmental protection at the same time. For both the smart home and Industry.
