The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also oil tank), and oil drip nozzle. The blower operates eccentrically with the rotor offset in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and expelled. During operation, the pressure difference of the blower is used to automatically send lubrication to the oil drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from flowing back. This type of blower is also called a sliding vane blower. The blower mainly delivers clean air, clean coal gas, sulfur dioxide, and other inert gases. Other flammable, explosive, corrosive, toxic, and special gases can also be produced and delivered on demand.
