The G 7-15 air compressors are available in 7kW, 11kW and 15kW variants with flows ranging from 13,8 to 32,5 l/s (29,2 to 69,9 cfm).
The 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
  • Base controller
  • Air-oil separator
  • Inlet air filter

Working Principle
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, through the after-cooler and into the receiver (if included). In the case of a Full Feature unit, the air will then circulate through the refrigerated dryer to leave the unit through to the discharge. In case of a Full Feature Tank Mounted unit, we have a dry tank, which increases the lifetime of the tank considerably.

Scope of supply
Oil Separator System, Oil Filter and Consumables
High efficiency 2 step air oil separator system for reduced oil consumption ensuring low maintenance costs and good oil separation result between 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.

Simplified Control and Regulation System
The icon based Base controller on the G 7-15 models include:

  • Running

Service warnings for optimal protection

  • Pressure - and element outlet temperature reading

Air Dryer (Full Feature models)
The integrated dryer efficiently removes moisture, aerosols and dirt particles to protect your complete installation. 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)
