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

Frequently asked questions
Do the rotors touch each other or the casing?
No. The two three-lobed rotors rotate in opposite directions with tightly controlled clearance, so there is no metal-to-metal contact and no lubricant enters the gas path.
Does output drop as the blower wears?
Not through impeller wear. The impeller and shaft are one integral piece, so the impeller does not wear and performance stays constant over long continuous runs.
Can this blower also run as a vacuum pump?
Yes. The same unit can be operated as a vacuum pump as well as a pressure blower.
What keeps oil out of the aeration air?
Reliable shaft seals: no oil leakage, so the gas output stays clean. The gas path itself is already oil-free because the rotors never touch.
