Roots blower

A roots blower is a mechanical device that moves air or gases by trapping a specific volume in paired rotors and then forcing it outward. Think of two lobed rotors (like gears without gears) that rotate in opposite directions inside a casing. As they turn, they trap air in the spaces between the lobes and the casing, then carry it to the outlet. This continuous process generates a steady flow of air or gas, often used in applications like aeration, pneumatic conveying, and vacuum systems. Roots blowers are valued for their reliable, steady airflow and ability to handle large volumes at relatively low pressure.
