ATLAS Copco’s Oil-free Air Division says it has proven the superior energy efficiency of screw technology for air blowers.
In a technical whitepaper, Atlas Copco concluded internal compression air blowers sets a new standard for energy efficiency in the low-pressure market, after comparing the technology with traditional ‘Roots’ type lobe technology.
The findings are based on tests which were witnessed and certified by the independent Technische Überwachungs-Verein (German Technical Monitoring Association, or TÜV).
The whitepaper found an average of 30% better energy efficiency. Screw technology is used in Atlas Copco’s range of ZS screw blowers for low-pressure applications and industries such as pneumatic conveying.
The range of ZS screw blowers uses the concept of internal compression, while the traditional “Roots” type lobe blowers rely on external compression to obtain an external system pressure.
