Product Description
DWT-II centrifugal roof fan
DWT-II centrifugal roof fan with centrifugal impeller, can be used in low wind, high pressure places. Type II uses a three-layer cover. Fans are divided into nine sizes according to the diameter of the impeller. The fan can be made into explosion-proof type according to the needs of different environments. They are suitable for non-corrosive places containing flammable and explosive gases. The anticorrosive type can be used in environments containing corrosive gases. In order to meet the user's performance adjustment requirements for different working conditions, the fan can be equipped with a two-speed fan to achieve two-speed speed regulation.
