1. What is an oil free screw blower?

Screw compressors delivering compressed air below 1.5 bar(g) are referred to as (rotary) screw blowers. The working principles of a screw blower are thus identical to those of a rotary screw compressor. Rotary screw blowers are used in a variety of low-pressure applications (wastewater treatment, pneumatic conveying, fermentation,…).

Sollant screw blower units are ISO 8573-1 Class 0 certified to protect your critical processes and products.

2. What are the advantages of screw technology? 

Energy costs can add up to 80% of the lifecycle cost of a blower. Screw blowers are type of positive displacement blowers. The internal compression process of a screw blower results in significantly lower energy consumption as a very limited amount of energy is transferred to heat. That is why screw blowers are an energy-efficient alternative to the classic rotary lobe blower solutions. On average, you can save up to 35-40% compared to lobe or roots style technology by opting for a highly efficient screw blower. The higher the pressure required by your application, the higher the potential savings and the lower your total cost of ownership.

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.
