roots blower for process gas boost application

Roots blower can be used to transport biogas, gas, air, oil and gas, etc. Because of the different gas properties, Roots blower needs special treatment. Which gases need special treatment for Roots blower?

1. Conveying special gas of biogas gas

     One of the questions asked by netizens is: Can a non-explosion-proof Roots blower transport biogas? Due to the flammability of biogas, it can burn when encountering an open flame at a certain concentration. Therefore, when transporting biogas, a Roots blower equipped with an explosion-proof motor must be used. At the same time, the Roots blower needs to be sealed to ensure that the biogas does not leak out.

2. Transport oil and gas medium gas

When conveying gas containing oil and gas medium, the content of oil and gas medium should be as low as possible. If the oil and gas content is high, Roots blower cannot be used for transportation. Reason: There is a certain standard for the impeller clearance of the Roots fan, and there should be no large errors. The high concentration of oil and gas will affect the impeller clearance and cause serious damage to the fan.

3. Conveying gas containing corrosive medium

For the gas containing corrosive medium, the Roots blower needs to be treated with anti-corrosion. If the corrosiveness is serious, the material of the Roots blower should also be removed, such as: stainless steel, glass fiber reinforced plastic, etc. When transporting such gases, the Roots blower also needs to be sealed to prevent leakage.
