Roots blower Bore: 50~500mm Flow capacity: 0.5~420m3/min Pressure rise: 9.8kpa~98.8kpa Vacuum: -49kpa Roots blower, sometimes called a positive displacement, or pd blower, is a machine which "pushes" a relatively constant volume of the gas handled at the inlet through to the discharge. It applies to conditions requiring high vacuum or high pressure especially in the waste water treatment plant. The main purpose of the blower is to provide constant flow of gas at different pressures. The blower consists of a cast iron casing in which two rotors with conjugate shapes rotate and are synchornised by a set of timing gears. During rotation, there is no contact between the lobes or between the lobes and the casing.

Roots blowers are used in numerous industries and industrial processes, including pneumatic conveying. Roots blowers play a vital role in many manufacturing and processing systems. Roots blowers are technically known as "positive displacement rotary blowers" and are commonly referred to as "blowers". What does a Roots blower do? Roots blowers are used to produce a constant airflow that is independent of the exhaust pressure conditions. The application of Roots blowers is limited to low and medium pressure and vacuum processes, and can be used to provide small to large airflow rates. How does a Roots blower work? Roots blowers consist of two identical and symmetrical rotors with two or three meshing blades in a sealed housing. The housing is valveless, and the air inlet and exhaust ports are usually located on opposite sides. The rotors rotate in opposite directions and are synchronized using a set of gears. The air is displaced from the inlet to the outlet by the movement of the meshing blades on the counter-rotating rotors. The airflow rate produced by the displacement is mainly determined by the rotational speed of the rotors within the Roots blower. There is no change in the amount of air within the Roots blower, so no air compression occurs. Roots blowers are typically air-cooled, and some models do not require oil as a lubricant (oil-free).

Roots Blower For Sale The Roots blower is a volumetric fan, with impeller end face and front and rear end covers of the fan. The principle is to use two blade shaped rotors to move relative in the cylinder to compress and transport gas in a rotary compressor. This type of blower has a simple structure and is easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement conveying, and is more suitable for gas conveying and pressurization systems in low pressure situations. It can also be used as a vacuum pump, etc. Type of Roots Blowers for Sale Roots Vacuum Pump Roots vacuum pumps have been applied in petroleum, chemical, plastic, pesticide, turbine rotor dynamic balance, aerospace space simulation and other devices, so they should be vigorously promoted and applied in China. It is also widely used in industries such as petroleum, chemical, metallurgy, and textiles. Rotary Air Blower Small size, large air volume, low noise, and low energy consumption (the rotary blower adopts the principle of operating compressed air, although small in size, it has large air volume, energy saving, and silent operation that other forms of fans cannot compare with.). Smooth operation and convenient installation (for small models, as long as they are properly placed, the vibration is minimal and there is no need to install anti vibration devices, making installation convenient). Resistance to load changes and stable air volume (for example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume changes very little with the pressure change). Equipped with an air chamber for smooth air dissipation (all models are equipped with an air chamber to prevent air pulsation and ensure smooth air dissipation). The material is excellent, the structure is clever, and the performance is stable (all blowers are made of high-quality materials, the structure is exquisite, sturdy and durable, the performance is stable, and there are few long-term failures). Simple maintenance, few faults, and long service life (low speed, low wear, and long service life).
