		GA 11 to GA 90 VSD
		Horsepower Range: 40 to 125
		Capacity: 203 to 604 cfm
		Pressure: 4 to 13 kg
			Atlas Copco pioneered the GA Variable Speed Drive compressors, offering the
		capability  to  match  perfectly  compressor  capacity  to  air demand. A GA VSD
		compressor  is able to follow the  fluctuating demand by varying  the  speed of  its
		drive motor. As air demand goes down, the GA VSD lowers the delivered flow and
		consequently  the  power  consumption. This is the key feature  of  the  GA  VSD
		compressors: They reduce  the  energy  consumption to a minimum  by  avoiding
		completely  unloaded  power  consumption  and  save up to 22% on  the total life
		cycle cost
		Atlas  Copco  designed  the  GA  VSD  range  according  to  the "WorkPlace Air
		System™" concept, offering  the  possibility  to  move  the compressor out of the
		conventional  compressor  room to the point of use. This concept has been made
		possible thanks to the extremely low noise levels & the integration of the optional
		ancillaries such as air and condensate treatment.
		The GA 18 - 90  VSD  units  are  delivered to the site equipped with oil and are ready to go. To start  the  operation, just plug in the
		compressor to its power  source. Maintaining a pipe network is cumbersome  and  costly. Besides the pressure drop  over the pipe
		network, experience shows that leakages of up to 10% of the total compressor capacity are not unusual. The "WorkPlace" concept
		offers the possibility to eliminate this unnecessary power consumption and save money.
		The GA 18-90 VSD series are available as :
		Air or water cooled versions.
		WorkPlace or WorkPlace Full Feature (including dryer) versions.
		High ambient versions (up to 145°F).
		Superior performance, cut energy costs by more than 35%
		Due to the variable speed drive technology, air demand & compressor capacity can be perfectly matched, avoiding unloaded power
		consumption completely.
		Very precise pressure control
		The GA VSD can keep the pressure within a ± 1.5 psig band, resulting in even more energy savings as every 7.25 psig reduction in
		delivery pressure reduces the power consumption with 3%.
		Pressure flexibility thanks to electronic gearing
		The GA VSD allows the user to choose any delivery pressure between 55 and 188 psig without needing to change gears or belts.
		Outstanding electrical characteristics
		The GA VSD draws no starting current peaks and has a high power factor avoiding penalties from electricity companies.
		Low noise level
		The use of a radial low speed fan and modern techniques of vibro-acoustic optimization has resulted in extremely low noise levels.
		All-in-one packages
		All air and condensate treatment  equipment  can be integrated into the compressor package, thus reducing installation costs and
		floor space requirements to a minimum.
