PRODUCT FEATURES AND ADVANTAGES

-Carbon steel axial flow rooftop fan adopts wide blade, large chord, space twisting and inclined blade shape, which can achieve the required air volume and partial pressure at low speed, thereby reducing fan noise.
-Fans are divided into 17 machine numbers from 300 to 2400mm according to the impeller diameter, with a series air volume of 15000 to 220000m3/h and a total pressure of 60 to 320pa. The blades of fans with machine numbers greater than or equal to 12 are adjustable to meet the needs of different working conditions and achieve energy saving and noise reduction.
-Fans can be made explosion-proof according to different environmental needs, and can be used in places containing flammable and explosive gases without corrosion. The explosion-proof type can be used in environments containing corrosive gases.
-In order to meet the performance adjustment needs of different working conditions, a dual-speed motor can be used to achieve two-speed speed regulation, or a variable frequency motor and a variable frequency controller can be used to achieve stepless speed regulation. It is recommended to lock the adjustment frequency at 25Hz ~ 50Hz.
