GA 5 – 11 (kw) Compressors

Atlas Copco GA 5 - 11 (kw) Compressors

GA 5-11 kw Oil Injected Roatary Screw Compressors

The GA5-11 is an oil injected rotary screw air compressor, available in 5kW, 7kW and 11kW, provide an energy efficient, reliable workplace air compressor that minimizes the total cost of ownership. A range of air compressors are designed to withstand the harshest of environments while providing you with a quiet air compressor with sound levels ranging between 60 and 62 dB(A). Atlas Copco’s GA5-11 series is designed and manufactured in accordance with ISO 9001, ISO 14001 and ISO 1217 which insures a reliable trouble free air compressor. Additionally, these units boast a very compact footprint and utilize the next generation Elektronikon® controller that offers you a great variety of control and monitoring features. This allows you to increase a compressor’s efficiency and reliability. As standard these units are designed to operate in 46°C/115°F ambient conditions and are available as a stand-alone compressor (Pack) or including an integrated dryer (Full Feature).

Atlas Copco GA5-11 air compressors – available in 5kW, 7kW and 11kW variants with flows ranging from 8.4 to 30.7 l/s (24.7 to 54.8 cfm).

The Pack (stand alone) compressors are constructed with the following major components:

  • State of the art compression element.
  • IP55 (TEFC) motor meeting or exceeding IEEE and NEMA Premium efficiency standards with greased for life bearings.
  • Elektronikon® controller.
  • High efficiency aftercooler.
  • Moisture separator.
  • Inlet air filter.

Additionally. the Full Feature (ff) model includes an integrated refrigerated air dryer using environmentally friendly R134a refrigerant

Compressor Working Principle:

1.1 Air / Oil Flow

Air is drawn in through the air filter and the inlet valve into the compression element. This compressed air is forced through the air/oil separator, past the minimum pressure valve and into the after-cooler through the water separator to the discharge. In the case of a Full Feature unit the air will then circulate through the refrigerated dryer and then to the discharge.

1.2 Cooling Systemair compressor

After the cooler an integrated water separator is installed, for a supply of cool compressed air free of liquid condensate to protect your production system.

1.3 Oil Separator System, Oil Filter and Consumables

High efficiency 2 step air oil separator system for reduced oil consumption ensair compressoruring low maintenance costs and good oil sepatarion result in between 2 service intervals.

 

The oil filter cleans the oil continuously from particles bigger than 25 micron with 99% efficiency in order to protect the lubrication quality and health of the rotating components.

1.4 Electrical/Control System

Reduced cubicle temperatures, by forced air ventilation through the cubicle, compressed air solutionsdoubles the lifetime of the electrical components and keeps the unit up and running even in the harshest conditions. Standard all units run without de-rating up to 46°C. Optionally high ambient versions are available for 50°C, on FF variants, and 55°C pack variants.

1.5 Air Dryer (Full-Feature models)

The integrated dryer efficiently removes moisture, aerosols and dirt particles to compressed air solutionsprotect your investment. This quality air expands the life of equipment, increasing efficiency and ensuring quality in your final product.

 

Pressure dew point at 3°C /37°F at maximum FAD. (100% relative humidity at 20°C/68°F)

 

Can be outfitted with optional DD and PD filters, allowing you to obtain the exact air quality you need for your specific application.
