This will include Atlas Copco’s ZS range of high-efficiency, oil-free, rotary screw blowers, as well as the company’s energy-efficient GA 7-37kW VSD+ compressor range, launched in 2013, which was recently expanded to include models up to 37kW.

GA VSD+ compressors are said to provide industry-leading energy savings of 50% on average, a 13% leap in Free Air Delivery and a canopy less than half the size of some traditional fixed speed compressors. This breakthrough in energy efficiency is made possible by Atlas Copco’s own 100% patented interior permanent magnetic (iPM) motors which drive, and form the heart, of all GA VSD+ compressors.

The GA 7-37 VSD+ is suitable for a range of applications in wastewater and clean water treatment plants including sand filter fluidisation, sludge tank aeration, sludge suspension, dissolved air flotation, surge vessel control, pneumatic control of valves and filter back flushing and cleaning.
