Atlas Copco have released a white paper explaining the technical differences and benefits between screw blower technology and traditional lobe-style blower technology. The white paper concludes that the introduction of air blowers using internal compression sets a new standard for energy efficiency in the low-pressure market.
 
Atlas Copco’s recently introduced full range of ZS screw blowers are on average 30% more energy efficient than lobe-style blowers. 

Blowers can typically represent up to 70% of the total electricity cost in Municipal and industrial wastewater treatment plants, and so by utilizing this new technology these plants will decrease energy costs while operating in a more efficient and environmentally friendly manner.
