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).
1.As a result of the use of three-leaves rotors and a box with a spiral, so the noise vibration of the roots blower is small.
2.Impeller and shaft as a whole structure, and no impeller wear, the performance of roots blower lasting unchanged, can long-term continuous operation.
3.High speed and high efficiency, and the structure is very compact.
4.Simple structure, due to adopt a special bearing, superior durability,
5.Model complete, can choose according to use selection.
