GreenTech International (Zhangqiu) Co., Ltd. is a professional supplier of Roots blowers. The M series Roots blowers (also known as positive displacement blowers, PD blowers, or rotary blowers) are heavy-duty new products from the United States. They are alternatives to the Gardner Denver Duroflow models, Dresser Roots RAM/RCS models, and Robuchi RBS models.

Heavy-duty oversized bearings are specifically designed to extend L10 life in industrial applications.
· Dual splash-proof aluminium oil sump design ensures the service life of gears and bearings.
· Integral ductile iron rotor and shaft, large shaft diameter, integral high-strength housing, and integral end plates reduce torsion and
vibration.
· Housing design accommodates horizontal or vertical installation configurations.
·Multiple piston ring air and oil seals minimise maintenance costs and ensure no cross-contamination of oil and air at delivery.
·Fluor rubber lip oil seals with O-rings prevent oil leakage.
·Wearable shaft filters prevent fluid leakage from the drive shaft, extending shaft life.
·Innovative three-lobe rotor profile and advanced housing design reduce noise and vibration.
