Rotary screw blowers are used in a variety of low pressure applications (wastewater treatment, pneumatic conveying, fermentation,…). Our screw blower units are ISO 8573-1 Class 0 certified to protect your critical processes and products.

Screw technology is the ideal technology for a variable speed configuration as the air compression energy efficiency level is rather constant at different operating points. Besides that, a very wide window of speeds can be obtained.
