The unique design of the V&W Series assures the long life and productivity. Our continuing program of product research and development assures that each Gardner Denver compressor includes the latest advancements in oil-less compressor technology. Internal moving parts in the V&W Oil-Less design are protected from wear without conventional lubrication. Crankshaft and rod bearings are lubricated by exclusive sealed, solid synthetic lubricants. Pistons move on alloyed heat-resistant filled Polytetrafluoroethylene guide and compression rings. The result is low maintenance, high durability and pure, oil-less air!
