In the chemical industry, Roots blower is used to transport sulfur dioxide in the sulfuric acid plant and smoke gas in the explosive plant. Roots blower made of ordinary materials is used for conveying sulfur dioxide. When conveying strong corrosive gases such as nitrous fume, the Roots blower made of corrosion-resistant stainless steel or the impeller with nickel phosphorus plating technology can be used

Roots blower is a constant volume fan without internal compression, and the delivery of gas is mandatory. With the change of pressure and flow, the change of flow is very small. The impeller adopts a special curve to ensure small leakage, high efficiency and high energy consumption. It is a new energy-saving product. The product adopts high-precision hard tooth surface synchronous gear, which has a long service life and low noise. The conveying gas is clean, and does not contain any high-quality dust. The product has a wide range of air volume and high grading density and pressure rise. More than 100 specifications.

Standardized design and production, patented manufacturing technology. The fan has low noise, and the inlet and outlet of the fan adopt spiral shape, so that the air inlet and exhaust process can be cut in the direction of the spiral line in order, avoiding the pulsating noise and vibration that will break out instantly when the old fan exhausts. This series uses an impedance composite muffler to further reduce noise. The fan rotor adopts advanced compound curve, which makes the engagement more reasonable and increases the volumetric efficiency. The rotor, casing, wallboard, shaft and other key parts of Roots blower are all equipped with advanced CNC machining center equipment to improve the interchangeability of parts.
