Screw compressors are positive-displacement compressors featuring two rotating screw rotors that compress air. They are the standard solution for industrial compressed air applications with constant demand and continuous operation.
Designs differ according to lubrication (oil-injected screw compressors for general industry, oil-free screw compressors for the food, pharmaceutical and electronics industries), by drive control (fixed or speed-controlled) and design (stationary, compact with integrated compressed air dryer).
Leading manufacturers include Atlas Copco, Kaeser, BOGE, Ingersoll Rand, CompAir, ALMiG, Mattei, Schneider Airsystems and Sullair.
Screw compressors are used in industrial manufacturing, in workshops, for supplying compressed air to pneumatic machinery, in paint shops, in sandblasting facilities, in the food and pharmaceutical industries, and in wood and metalworking.
