operating principle of pressurizing fan
When the motor drives driving shaft to rotate by coupler or belt wheel, the gear in driving wheel drives the gear in driven wheel to rotate synchronously in the reverse direction along with its rotor to rotate which forms a space between the rotor and the shell. Air enters the space through air inlet, air would be compressed and squeezed out of air outlet by rotor and another rotor turns to the relative position where the first rotor begins to compress which forms a new space with the other side of the shell and new air enters this new space and be squeezed out. Continuous motion is the cause of air blowing.
