Tohin rotary vane blower mainly consists of components such as Blower body (cylinder), Motor, Air chamber, Air filter, Base (with oil tank), and Oil dropping nozzle. This simple structure contributes very long life and trouble-free operation.

The rotor, which has four pieces of vane moving in-and-out repeatedly, eccentrically rotates in the cylinder to intake, compress, and discharge air. This is the basic mechanism of the blower.

While running the machine, lubricating oil keeps circulating and continuously supplied to the cylinder through the oil dropping joint. The oil works not only to decrease operation sound and friction heat, but also to keep high airtightness in the cylinder.
