OIL FILTER- A high etficiency oil filter removes 300% smaller particlesthan a conventional filter, providing clean oil to extendthe lifetime of all lubricated parts in the compressor.

- The oilfilter rating of 812=75 sets a new industrial compressorstandard that is fully compliant with ISO 1 6889.

Elektronikon': A Superior Electronic Control,Monitoring And Communication System

Atlas Copco's patented Elektronikon' is an advanced,microprocessor based, real time operating system with an ergonomic

alphanumeric user intedace. To maximize energy efficiency, the Elektronikon controls the main drive motor and regulates system

pressure within a predefined and narrow pressure band. With a simple push of a button, you can remote stad and stop, load and

unload the compressor.

MULTIPLE COMPRESSOR CONTROLThe Elektronikon's Multiple Compressor Control (MCC)

centrally controls up to four compressors simultaneously.The result is a substantial reduction in system pressure

and energy consumption, in addition to minimalcompressed air leakage and a more stable pressure

acrossthe network.

The Elektronikon continuously monitors critical parameters.Monitoring features include service and warning indications,error detection, compressor shut-down and maintenance scheduling'

. The GA can operate close to the point of use - eliminatingthe need for a dedicated compressor room.

. The GA is delivered ready for use - minimizing productiondowntime and reducing installation costs.

Revolutionary WorkPlace Concept

With its compact footprint, low noise operation and integration of airand condensate treatment equipment, the GA offers completeversatility for your production. The GA's integrated design allows thecompressor to be placed on the production floor, reducing externalpiping costs and minimizing pressure drop across the system. Thisincreased efficiency can create strong energy savings for yourbusiness.

Lowered Installation Costs

. With filtration equipment integrated, the GA reduces the needfor costly external piping.

A conventional compressor, with external filtration equipment andhigh noise operation, has to be placed away from the work floor.Thiscreates external pipeworkwhich can raise installation costs.

The GAWorkPlace, with its low noise operation can be placeddirectly at your point of use. This integration saves space andreduces piping costs.

. The GA operates at the lowest possible system pressure toreduce energy costs thanks to the Elektronikon'advancedmonitoring system-

Reduced Energy And Maintenance Costs

. With less piping in the workplace, the GA minimizes pressure dropAcross the system which can reduce energy costs.

. Thefiltration system produces clean airto prevent network corrosionminimizing energy, repair and maintenance costs.

Standard

Placed away from the workfloor, external piping is increased whichcan create higher pressure drop across the system.

The GA's integration reduces pipework which minimizespressure drop from the compressor to the work floor.

Delivering Quality Air

The integrated refrigerant dryer, standard with the Atlas CopcoGA WorkPlace FE reduces installation and maintenancecosts, as well as required floor space. The dryer comes withthe innovative SAVER cycle technology which limits therunning time of the dryer while ensuring a good dewpointto protect your system from moisture.

Untreated compressed air contains moisture, dirt particles andaerosols that can damage your entire air system. The resultingmaintenance and downtime costs can far exceed air treatmentcosts. The GA WorkPlace Air System integrates air andcondensate treatment equipment into one canopy, right onyour work floor. The air from the GA WorkPlace Air System willsee the quality of your production improve while youroperating and maintenance expenses decrease.

Protecting You r Prod uction

Untreated compressed air contains moisture, aerosols and dirtparticles that can damage your alr system and contaminate your endproduct. Resulting maintenance costs can far exceed air treatmentcosts. We believe in effective orevention.

INCREASE YOUR PRODUCTION RELIABILIWLow quality air heightens the risk of corrosion in yoursystem, which can lower the life span of your air toolsand production equipment. The GA's filtration processproduces clean air that enhances your system's reliability,avoiding costly downtime and production delays.

REDUCE YOUR ENERGY COSTSClean, treated air reduces the risk of corrosion and leaksin your compressed air system. A 3 mm leak could easilyadd up to1800 to your energy bill annually.

SAFEGUARD YOUR PRODUCT OUALIryCompressed air coming into contact with your finalproducts should not atfect their quality. The GA providesthe clean, dry air that will protect your product'sreputation in the marketplace.

PROTECT THE ENVIRONMENTWith leaks and energy waste minimized and the unsafedisposal of untreated condensate eliminated, you cansafeguard the environment and comply with stringentinternational regulations.

GA VSD: The Compressor GeniusThat Can Save Up To 35 % Of EnergY

A typical air demand profile,measured over one week.

Most oroduction facilities show an air demand profile withfluctuations according to the hour ol the day, the day of theweek or the period in an economical cycle. TraditionalCompressors can notfollow preciselythe air demand.

Atlas Copco pioneered the GA V(ariable) S(peed) D(rive)

compressors, offering the capability to match perfectlycompressor capacityto air demand.

A GA VSD compressor is able to follow the fluctuatingdemand by varying the speed of its drive motor. This is thekey feature of the GA VSD compressor. They reduce theenergy consumption to a minimum by avoiding completelyUnloaded power consumption and so save up to 22% on thetotal life cycle cost.

A measurement box is used for analysis of air energyconsumption. Based on these readings, the implementationof a VSD compressor in a typical installation can be simulatedby software. Future energy savings can be estimated prior toany capital investment commitment.

The Atlas Copco VSD Advantage

Designed and manufactured in accordance with ISO 9001 certification, the GA

30-SSC range meets the industry's expectations of the highest quality

standards. All units conform with ISO 1 21 7, edJ, Annex C - 1 996 test code.

The compressor has been designed to be service friendly with direct and easy

access to all components. Wear and the need for spare parts are reduced to a

minimum.

The use of a low noise fan and modem techniques of vibro-acoustic

optimization has resulted in extremely low noise levels.

This advanced control, monitoring and communication system maximizes

overall compressor efficiency and reliability and minimizes maintenance cost.

At the same time all worldwide interfaces for remote control and

communication are available.

All air and condensate treatment equipment can be integrated in the

compressor package reducing the installation cost and floor-space

reouirement to the full.

From concept to installation, from advice to preventive maintenance and

service activities, Atlas Copco is your compressed air partner helping tomaintain your production process.

Thanks to the variable speed drive technology, air demand and compressorcapacity can be perfectly matched, avoiding unloaded power consumption

completely.

The GA VSD can keep the pressure within a 10.1 bar band, resulting in even

more energy savings as every 0.5 bar reduction in delivery pressure reduces

the power consumption.

The GA VSD allows the user to choose any delivery pressure between 4 and 13

bar without any gears or belt to be changed.

The GA VSD draws no starting current peaks and has a high power factoravoiding penalties from electricity companies.
