Atlas Copco Compressors has expanded its AQ oil-free, waterinjected screw compressor range with new models from 15 to 30 kW installed motor power that incorporate ‘energy-efficient’ Variable Speed Drive (VSD) technology.
The new Class 0-certified AQ 15-30 VSD range comprises four different models, including air and water-cooled variants, and can reportedly offer ‘substantial energy savings and high operational efficiency for oil-free applications’. With the latest compressors, Atlas Copco now offers water-injected screw compressors from 15 to 55 kW installed motor power. The company said: “The new compressors bring reliable, ISO 8573-1 Class 0-certified, oil-free air to the most sensitive applications below 30 kW, including medical, pharmaceutical production, food processing, electronics, and >8 bar pressure applications. VSD technology matches compressor output to air demand, leading to energy savings ‘of 35% on average’, while noise levels are as low as 67 dB(A).” The units’ element bearings are water-lubricated and slide on the water, extending their lifetime, and ensuring smooth element rotation.
