The new GA15-26 oil injected screw air compressors, available in 15kW, 18kW, 22kW and 26kW, provide an energy efficient, reliable work place air compressor that minimizes the total cost of ownership. These air compressors are designed to withstand the harshest of environments while providing you with a quiet air compressor with sound levels ranging between 65 and 69 dB(A). The GA15-26 series are 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 cool canopy design which increases efficiency and free air delivery. The GA15-26 units also utilize the next generation Elektronikon® controller that offers you a great variety of control and monitoring features that allow you to increase you 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) .
The GA15-26 air compressors are available in 15kW, 18kW, 22kW and 26kW variants with flows ranging from 30.9 to 74.3 l/s (65.5 to 157.5 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 IE3 and NEMA Premium efficiency standards with greased for life bearings
- Elektronikon® controller
- High efficiency aftercooler
- Moisture separator
- Inlet air filter
Additionally the Full Feature includes an integrated refrigerated air dryer.
The GA15-26 Air Compressors consist of the following:
1.1 Air / Oil Flow
Air is drawn in through the air filter, 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 Drive Train
The high quality gear driven design does not use couplings which eliminates a maintenance point. The design of the gears has eliminated transmission losses that are typically 2-3% higher on belt driven units. The compression element has also been redesigned to provide even more free air delivery.
1.3 Air/Oil Separator System
The high efficiency air oil separation system provides excellent oil pre-separation with >99% of oil separated in the vessel providing less than 3ppm oil carry over. Due to the innovative design the chance for overfilling the unit has been eliminated. Additionally the compact size of this vessel there is less oil required and less compressed air blow off when the unit unloads resulting in money savings for you.
1.4 Cooling System
The reliable and efficient design of the combicooler effectively lowers the discharge temperature of the compressed air which reduces the burden placed on downstream air treatment equipment and provides better protection of air network piping. Additionally the low sound and low power consumption from the cooling fan makes these new units even more silent and efficient than ever.
1.5 Air Dryer (Full-Feature models)
The integrated dryer efficiently removes moisture, aerosols and dirt particles to protect 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.
