The Roots blower is a positive displacement rotary blower that achieves gas conveyance through the counter-rotation of two intermeshing impellers within the casing.
The main functions include:
Gas delivery function: Capable of delivering air and other neutral gases stably and continuously
Pressure supply function: Capable of generating an exhaust pressure ranging from 0.1 to 0.8 kgf/cm²
Vacuum forming function: It can be used as a vacuum pump to create a negative pressure environment
The main applications cover the following fields:
Wastewater treatment industry: used for oxygenation in aeration tanks to promote microbial metabolic activity
Aquaculture industry: providing oxygen to the breeding pond and increasing the dissolved oxygen content in the water body
Pneumatic conveying system: Provides motive airflow in the conveyance of powder and granular materials
Printing machinery accessories: used for paper separation, suction feeding, and drying processes
Electroplating bath agitation: Uniform distribution of electrolyte through bubble agitation
Combustion support for burners: Providing the required air flow and pressure for industrial burners
