Roots Blower By Type
Based on similar rotating impeller principles, Roots blowers are divided into three types: Roots blowers, Roots vacuum pumps and steam compressors, each with different designs and uses. 
Roots blower is a positive displacement blower, mainly used to transport gas or to pressurize gas.
Roots vacuum pump is a device used to extract gas and reduce the pressure inside the container to form a vacuum environment.
A steam compressor is a machine specifically designed to increase the pressure of steam, which increases the energy of the steam so that it can be used more efficiently in industrial processes.
