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

We switched eight ponds to microporous tubing — electricity dropped by about a third and the crop grew through the hot season.

Quick answers

Frequently asked questions

How much oxygen does my pond need?

Keep dissolved oxygen at 3-5 mg/L at the pond bottom; below about 2 mg/L fish stress and mortality start, especially around dawn. Monitor at depth, not at the surface.

What's the difference between microporous tubing and paddle wheels?

Microporous tubing oxygenates the bottom layer where fish rest at night, with about 50% lower energy use; paddle wheels mix the surface and are best kept as emergency backup.
