Atlas Copco says that its new high-pressure, portable compressor line-up offers versatility and mobility for a vast array of construction jobs. There are four variants offered so far, the XRVS1050, XRHS1150, XRYS1150 and XRVS1210. All four share features including a new screw element design that is said to be highly efficient and reduces energy consumption by 3% over the previous range. Increased fee-air delivery and reduced fuel consumption are also benefits of this improved screw element layout. A novel control system that is easy to use is also offered with this compressor range. Functions for the Xc3003/4003 controller package include engine diagnostics, advanced flow-pressure management, dual pressure selection and even a high altitude setting.
