The vacuum pump vanes create vacuum or compression. The vacuum pump vanes located eccentrically in the rotor grooves reduce the working space, and create vacuum or compression. Vacuum pump vanes are produced of two materials, either carbon or, to put it simply, plastic. Vacuum pump vanes made of carbon are used in dry-running, oil-less vacuum pumps and compressors with continuous wear, since the vane itself is the lubricant.
