The NASH WITTIG RVA-G is a once through, oil lubricated rotary vane compressor for gas applications.
Cooling can be achieved by either fresh water or pressurized re-circulation water. The RVA-G is supplied as compact units which are mounted on a torsion resistant base frame. They can be drive by electric motors (explosion proof if necessary) via flexible coupling.
The RVA-G is well suited for compression of natural, process, and digester gas.
