Atlas Copco GA 15-26 kW compressors get an efficiency boost

Hydrocarbon Engineering,


Atlas Copco has released an updated GA 15-26 range of economical and reliable solutions for applications that require a constant flow of compressed air. This ‘fixed speed’ oil injected screw compressor offers improved free air delivery at reduced power consumption and lower noise levels.

Compared to the previous GA 15-22 range, the new GA 15-26 offers increased performance (free air delivery up with 5%) and lower power consumption (specific energy requirement down with 2%).

Bert Derom, Vice President Marketing, commented: “For decades, our GA 15-22 has been the perfect solution for workshops, installation companies and OEMs all over the world. This oil injected screw compressor is renowned for its reliability and low costs of ownership. With this update, we did not touch any of the benefits, we just made our GA even better and extended the range to 26 kW”.

Major energy and performance improvements come from the GA’s drive train, which features an IE3 motor (NEMA Class 1) and a new, in house designed compressor element. Compared to belt driven variants, the gear driven GA 15-26 wins 3% in efficiency. Reduced pressure drops and improved cooling flow account for another 2% performance increase, bringing the total free air delivery gain to 5% on average, over the complete range.

The GA delivers more air at the same power consumption and does so in silence. The new drive train is more energy efficient and also the new cooling fan consumes less and is quieter than its predecessor. Overall, the specified energy requirement (SER) is improved with 2% on average. All these new components have reduced the sound level of these units to as low as 65 dB9A), making a major difference when the compressor is operated close to the point of use.

To tailor the GA 15-26 to any requirement a workshop may have, a wide range of options is available. They include integrated dryer and filters for high quality air, a factory mounted receiver and various solutions for extreme climates.
