Greentech International (Zhangqiu) Co., Ltd

The three-lobe blower is a new series of root-type blowers. Through CNC machine tools, we manufacture precision rotors to enhance performance and reduce noise and vibration.
Wide range of air volume, pressure, and vacuum, 1. Bore: 40A~400A (1.5"~16") 2. Capacity: 0.5~360 meters/min 3. Pressure: 0~8000mmAg4. Vacuum: -5000 mmAq airflow is adjustable with minimal pressure variation. Keep the air clean and not humid. Simple structure and easy maintenance, bearings are lubricated by oil and wet methods.
Noise reduction: The pressure advantage is the main source of noise for hair dryers. The three-cam design efficiently reduces noise by about 5dB. Bearing lifespan is extended. The vibration transmitted through the cam extends bearing life by about 20%.
