Gardner Denver rotary screw air compressors are designed to meet the highest requirements of a modern work environment. Easy to implement into any sized compressed air system, our rotary screw air compressors provide efficiency, low noise emissions, and robust performance.
Rotary screw air compressors, sometimes known as twin screw compressors, are the most universal compressors used today. Because of their wide range in size and power specifications, rotary screw air compressors are used in large mass production factories as well as small family business shops.
Rotary compressors contain two rotors, categorized as male and female, with each rotor comprised of a set of helical lobes affixed to a shaft. The female rotor has typically more valleys (flutes) than the male rotor lobes. As air enters the compressor through the inlet valve, it becomes trapped between the two rotors. As they turn, the air pressure is increased by reducing its volume.
Low maintenance – Oil coated parts have a much longer life expectancy. In fact, in most cases the rotors of rotary screw processor never have to be replaced.
Cooling - The compressor is cooled by the injected oil so water-cooling is not needed.
Sealing – The oil creates a seal in the compressor preventing the air from seeping out.
Noise Reduction – The oil lubricates moving parts so less friction is produced.
Our new designs use Premium Efficiency Air Ends and Integrated Heat Recovery systems. When implemented into compressed air systems, these features make our rotary screw compressors flexible, powerful, yet efficient.
Our rotary screw air compressors have been designed to provide top efficiency and reliability. They can be used in low, high or variable air pressure systems, and in controlled as well as harsh conditions.
