The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and fuel tank), drip nozzle. The blower relies on the eccentric operation of the biased rotor in the cylinder, and the volume change between the blades in the rotor slot will suck in, compress and spit out air. In operation, the pressure difference of the blower is used to automatically send lubrication to the drip nozzle, drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder does not return, such blowers are also called slip-vane blowers
