Vanes are made in the range of carbon material (carbon graphite) metal impregnated carbon graphite and resin-bounded graphite to meet many different applications. Carbon vanes are self-lubricating and therefore ideal for pumps, handling liquids whose lubricating properties are poor, such as petrol, diesel etc. They can also operate in unlubricated compressors to deliver air or gas uncontaminated by lubricating oil or grease.
