The rotary
blower has a delicate structure and is generally composed of six parts: a motor, a gas coupling, a centrifugal blower itself, a gas chamber, a base (also an oil tank), and a drip nozzle.
The centrifugal blower runs on the eccentricity of the motor rotor biased in the cylinder, and causes the capacity of the four blades in the motor rotor slot to change each other to suck in, recompress, and eject the gas.
The centrifugal blower mainly uses the pressure difference to automatically send the lubricating oil in the oil tank to the drip nozzle. Once the blower is running, it drops into the cylinder to reduce friction and noise.
