ZR & ZT 15kW-55kW (VSD) oil-free screw air compressors

Economical, high quality oil-free air

Clean, oil-free compressed air is a prerequisite for the continuity and quality of many manufacturing processes. Over the past decades, Atlas Copco has pioneered the development of oil-free rotary tooth technology, resulting in a full range of highly reliable compressors delivering 100% oil-free, clean air. With the protection of your application in mind, the ZR/ZT series gives you all of this experience in a class leading package and meets your every need for pure oil-free air.

Proven technology, maximized efficiency

To provide you with top-quality, 100% oil-free air, our ZR/ZT series incorporate a range of advanced technologies. The unique rotary tooth element increases efficiency thanks to two-stage compression. As no venting of the pressure element is required, the energy consumption is considerably lower compared to single stage compression systems. With its symmetrical and dynamically balanced design, the double tooth element ensures an increased free air delivery and delivers consistent performance over time.

Variable speed drive (VSD) energy savings add up

Over 80% of a compressor's lifecycle cost is taken up by the energy it consumes. The generation of compressed air can account for more than 40% of a plant's total electricity bill. To cut your energy costs we have pioneered Variable Speed Drive (VSD) Technology in the compressed air industry. Atlas Copco's VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in energy savings of up to 35%.
