Chemical and pharmaceutical fields:

Roots fans are used in gas delivery and ventilation systems in the chemical and pharmaceutical industries, as well as in drying and cooling gases produced in

 chemical reactions. During the transportation of raw materials and finished products. For example, various granular or powdered materials are transported to

 the dryer or mixer, and the flow rate is adjusted; Or transport the products from the reactor to the subsequent processing equipment. In these processes, because

 of its large conveying capacity, Roots fan can meet the transportation needs of various materials with different viscosity and specific gravity, and its good sealing,

 it can achieve oil-free compression of the fluid, so as to ensure the purity of the transported materials, which is often used to transport chemical raw materials 

such as chlorinated dilute, polyethylene and other granular.

In the medical field, screw blowers also play an important role; It can be used in a variety of medical equipment, such as ventilators, oxygen machines, etc., to 

provide stable gas delivery and pressurization for patients, the normal operation of medical equipment, and improve the treatment effect.
