Excellence in air qualityUntreated compressed air contains moisture, aerosols and dirtparticles that can damage your air system and contaminate yourend product. The resulting maintenance costs can far exceed airtreatment costs. Our compressors provide the clean, dry air thatimproves your system’s reliability, avoiding costly downtime andproduction delays, and safeguarding the quality of your products.Clean, treated air also reduces the risk of corrosion and leaksin your compressed air system, leading to substantial costsavings. Furthermore, with leaks and energy waste minimized andthe unsafe disposal of untreated condensate eliminated,you can protect the environment and conform to stringentinternational regulations.SAVINGS FEATURES On average 40% energy savings with R410A integrated dryersLow pressuredrop G lobal warming potential has been reduced significantlyby an average of 50% with the introduction of the R410A refrigerant.Energy-efficientrefrigerant R410A Use of energy-efficient refrigerant R410A reduces operating costs.Saver CycleControl Environmentally friendly characteristics.

WorkPlace: complete versatility, total capabilityWith its compact footprint, low noise operation and integrationof air and condensate treatment equipment, the GA offers completeversatility for your production. The GA ’s integrated design allowsthe compressor to be placed on the production floor, creatingstrong energy savings for your business.Lowered installation costs The GA can operate close to the point of use – eliminatingthe need for a dedicated compressor room. With filtration equipment integrated, the GA reduces the needfor costly external piping and minimizes pressure drop. The GA is delivered ready for use – minimizing productiondowntime and reducing installation costs.A conventional compressor, with external filtration equipment andhigh noise operation, has to be placed away from the production area.This lack of integration can raise installation costs.The GA WorkPlace, with its low noise operation and integratedcondensate and air treatment equipment, can be placed directlyat your point of use. This integration saves space and reducespiping costs.Reduced energy and maintenance costs With less external piping, the GA minimizes pressure dropacross the system which can reduce energy costs. The filtration system produces clean air to prevent networkcorrosion – minimizing energy, repair and maintenance costs. The GA operates at the lowest possible system pressureto reduce energy costs thanks to the Elektronikon advancedmonitoring system.INTEGRATED CONDEnSATE MANAGEMENT OSCi is an efficient integrated solution that removes oilfrom condensate. Oil carryover contained in condensate can harmthe environment. Treated condensate protects water, wildlife and ecosystems. The delivered water is harmless and can be disposedin a sewage system, reducing disposal costs.

Variable Speed Drive: driving down energy costsEnergy can represent over 70% of a compressor’s lifecycle costs(LCC). Generating compressed air can account for more than 40%of a plant’s total electricity bill. Most production environments havea fluctuating air demand depending on the time of day, week, oreven months per year. Atlas Copco’s Variable Speed Drive (VSD)technology mirrors air usage - automatically adjusting the motorspeed depending on demand. With VSD technology, Atlas Copco hasmade major energy cost savings a reality, while helping to protectthe environment for future generations.LOAD – NO LOAD: FIXED VOLUME, HIGH COSTSAir DemandENERGY COSTTIMEAir DemandStandard CostsVSD: Variable Volume, Controlled CostsAir DemandENERGY COSTTIMEAir DemandVSD CostsTraditional compressors working with a full load, no load controloperate between two set pressure points. When maximumpressure is reached, the compressor goes off load. During periods ofmedium to low air demand, the no load power consumption can beexcessive – wasting large amounts of energy.Because there is no unnecessary power generated, the GA VSD canreduce energy costs by 35% or more. Lifecycle costs (LCC)of the compressor can be reduced by an average of 22%.In general, the extra cost of a VSD compressor comparedto a fixed speed one can be earned back after just one to two years.LIFECYCLE COSTS OF A COMPRESSORLIFECYCLE COSTS OF A VSD COMPRESSOREnergy ConsumptionEnergy nceInstallationInstallationAverage 35% Energy Savings
