EC137-A500-001
Product description:

This series of new products has been developed in-house. Diameter range is from φ250 to φ500 mm and maximum air volume is up to 10,000m3/h.This external rotor fan series has a compact structure, operates reliably and is both energy saving and efficient. It is designed with low noise, a long service life, and is easy to install.Designed with a forward-curved airfoil profile, the blade has obvious advantages in both energy efficiency and noise performance, when compared with conventional blades.In addition, lightweight plastic and aluminum alloy materials are available for customers to choose from for different applications – making it more adaptable for varied environments.The use of plastic for blades reduces the load on both bearings and the entire rotor power system - further improving product reliability and service life.EC/DC motors drive the fan more efficiently and make it easier to control, in order to flexibly meet customers’ speed regulation and control requirements.Dunli EC/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.
