3L Roots blowerDetailed product description：

3L Roots blower

The three bladed Roots blower is a positive displacement Roots blower, and the output air volume is proportional to the speed. The three bladed impeller engages with two impellers for 6 suction and exhaust cycles per revolution. Compared with the blade shape, the gas pulsation is small, the vibration is also small, the noise is low, the sealing distance is long, and the pressure is high. The impellers on the two shafts of the fan always maintain a small gap between the inner hole surface of the elliptical shell, the end face of the impeller, and the front and rear end covers of the fan, as well as between the fan impellers. Under the drive of the synchronous gear, the air is transported from the fan inlet along the inner wall of the shell to the exhaust side. The fan chamber does not require lubricating oil, has a simple structure, operates smoothly, and has stable performance, making it particularly suitable for underwater aeration and oxygenation in aquaculture.
