Carbon Graphite Vanes

Carbon Graphite Vanes

Helwig Carbon Products has been manufacturing vanes from carbon graphite for over 40 years. Our specialized carbon graphite material is the ideal vane material for dry running oil-less vacuum pumps and compressors. Dry running vane pumps have many advantages over other types of pumps. They offer smooth - pulse free air flow, require no lubrication with minimal noise and vibration in a compact design. They produce maximum vacuums and have high air flow rates combined with easy maintenance and long service life.

Specialized materials are stocked in various grades and sizes in order to manufacture vanes quickly. With our custom grinding equipment we maintain the challenging tolerances required to obtain the best performance from our vanes.

In addition to vanes; Helwig also manufactures carbon graphite rotors, end plates, and liners.
