The Enchoy rectangular fan, the direct-connected EKRB centrifugal duct fan, is a straight-through radial flow fan. The fan has a compact structure, a relatively large air volume, and is easy to install. While operating with appropriate noise levels, the EKRB fan can withstand relatively high wind pressures and is suitable for long - duct air transportation.
The EKRB series of fans are moisture - resistant. The fan housing is made of hot - environmentally friendly riveted galvanized steel sheets, and the surface is treated by spraying, which makes it corrosion - resistant and allows installation in moist or wet environments. The EKRB series has relatively large external dimensions, which makes cleaning and maintenance more convenient. The fan is equipped with a high - efficiency backward - inclined impeller.
When the temperature inside the motor winding is too high, the internal thermal switch of the motor will automatically disconnect, effectively protecting the motor.
The fan uses an EC variable - frequency DC brushless motor, which is more energy - efficient. It achieves 0 - 100% stepless speed regulation through a 0 - 10V voltage input.
