Gardner Denver rotary screw gas ends are well suited for natural gas compressor applications. All Gardner Denver gas compressors are constructed of ferrous metal. No yellow metals are used in the gas end construction. This allows the Gardner Denver Rotary Gas Compressor to be used in virtually any natural gas application. Rotary screw gas ends are designed to be used in a lubricant flooded system. Coolant/lubricant flowing through the Rotary Gas Compressor protects the internal components from corrosive vapors. Optional drive arrangements for Gardner Denver Rotary Gas Compressors range from plain face and keyed shaft for “C” and “D” flanges and SAE engine mounts for engine-driven applications.
