Three-Blade Roots Fan
A three-lobe positive-displacement Roots blower for aquaculture aeration, sewage aeration and pneumatic conveying. The rotors never touch, so the gas path stays oil-free and the discharge clean.
Features
- Two three-lobed rotors rotate in opposite directions with tightly controlled clearance — no metal-to-metal contact, no lubricant in the gas path
- Integral impeller-and-shaft design: impeller does not wear, performance stays constant over long continuous runs
- Low gas pulsation, low vibration and low noise
- Reliable shaft seals — no oil leakage, clean gas output
- Compact structure, high speed, high efficiency
- Can also be operated as a vacuum pump
