Gas ROOTs Blower units

Shangu Gas Roots Blower is specially designed for biogas, natural gas, coal gas, alcohol mixture, straw gas, and other combustion gases, harmful and toxic gases. With Packing Seal, Piston Ring Seal or Mechanical Seal, it can prevent the leakage of the gas from the blower.

We currently produce 15 sizes of Gas ROOTs blower units.

Frequently asked questions

For all sizes of unts, we produce our own acoustic covers, adapted to the location and customer requirements. These in conjunction with our silencers show a high noise attenuation efficiency.
At the same time, we design the set in the middle band of the speed spectrum so that the resulting sound pressure level is as low as possible.

If we know all the parameters, then processing and sending the offer is a matter of a few hours.
