Roots Blowers are positive displacement Blowers. The amount of air delivered is proportional to the number of revolutions. There is always a small gap between the impeller end face, the front and rear cover of the Blower, and between the Blower impeller. The synchronization gear drives the downwind from the Blower inlet along the shell. The inner wall is transported to the side of the discharge. Roots Blowers are used in many fields such as petrochemicals, building materials, electricity, smelting, chemical fertilizers, mining, ports, textiles, food, papermaking, aquaculture and sewage treatment, environmental protection industries, etc., most of them are used to transport air, but also can be used to transport gas, Flammable, explosive and corrosive gases such as hydrogen, acetylene and carbon dioxide.

Roots blowers can be roughly divided into single-stage and double-stage according to their different working methods. There is only one compression-stage blower, which we call a single-stage blower, and two single-stage blowers are connected in series to continuously A blower that performs two compressions is called a two-stage blower. According to the number of impeller heads: two-lobe Roots blower and three-lobe Roots blower; according to use: vertical kiln blower, gasification blower, aeration blower, etc .; by media type: air blower, gas blower, hydrogen blower, sulfur dioxide Blowers, etc .; Divided according to transmission method: direct-connected blowers and belt-connected blowers, etc .; According to cooling methods: air-cooled blowers, water-cooled blowers, and counter-current cooling blowers; etc. And densely integrated group blowers, etc. According to the type of seal: various types of blowers such as labyrinth seals, ring seals, packing seals and mechanical seals.
