Atlas Copco proves efficiency of for air blower screw technology19 July 2010

Air blowers using internal compression, instead of conventional external compression, set a new standard for energy efficiency in low-pressure industry.

That is the main conclusion of a whitepaper published by Atlas Copco's Oil-free Air Division, explaining the differences between its TÜV certified screw technology and the traditional Roots type lobe technology.

The 30% more energy efficient screw technology is used in the manufacturer's recently introduced range of ZS screw blowers for low-pressure applications and industries such as wastewater treatment and pneumatic conveying

"Over the past 50 years the blower market for small volume flows has not seen any major technical improvements," comments Chris Lybaert, president of Atlas Copco's Oil-free Air Division.

"The only considerable development we have seen with the Roots type lobe blowers, was the reduction of pulsation levels. Atlas Copco achieved [energy efficiency improvements] by developing the twin screw design for a low pressure blower. By doing so we introduced a technological advantage in this market segment."
