Conveyor of sulphur dioxide using general materials Roots blower, conveyor of nitrous oxide and other highly corrosive gases, corrosion-resistant stainless steel can be selected or the impeller also uses nickel-phosphorus plating technology Roots blower.

Roots blower is a fixed capacity fan without internal compression, conveying gas has a mandatory, with the pressure changes in the flow rate of change is very small impeller using a special curve to ensure that the leakage of small high efficiency, high energy consumption is a new type of energy-saving products. Products using high-precision hardened synchronous gears, long life and low noise, conveying gas clean, does not contain any high-quality dust, the product air volume range of wide, dense staging high pressure rise. More than a hundred kinds of specifications.

In the chemical industry, Roots blowers are mainly used as a means of transporting sulphur dioxide in sulphuric acid plants and nitrous oxide gas in explosives plants.
