Roots blower main specifications

Fan, blower, wind turbine. Gas compression and gas conveying machinery is a kind of machinery which converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports gas out.


The main structural components of Roots blower are impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearing), etc.


Unpowered fan is to use the natural wind and indoor and outdoor temperature difference caused by the air thermal convection, to promote the turbine rotation, so as to use centrifugal force and negative pressure effect to exhaust indoor hot air.
