Rotary Screw Air Compressor Technology

Rotary screw technology employs two helical rotors—a male and female screw—that rotate in opposite directions within a compression chamber. As the rotors turn, air is drawn in and progressively compressed as it moves along the length of the screws towards the discharge port. This continuous compression process results in highly efficient pressure generation and smooth, pulsation-free air delivery.

Oil-free air compressors explained

Oil-free rotary screw compressors are designed to produce compressed air certified to Class 8573-1 standards, making them ideal for sensitive applications. Modern designs prioritise quiet operation through sound-proof insulation, with noise levels as low as 60 dBA in some models. The absence of lubrication in oil-free variants eliminates the risk of oil contamination and reduces the need for inline filtration, producing completely clean air suitable for demanding industrial environments. With minimal moving parts and robust construction, rotary screw compressors offer thousands of hours of trouble-free operation with low maintenance requirements, making them a reliable investment for continuous-duty applications.
