Roots Rotary Lobe Blowers with Tri-Lobe design and brushless DC electric motors deliver reliable, oil-free air movement for demanding industrial applications.

Roots blowers are positive displacement rotary compressors that operate without internal lubrication. Two rotors with precisely controlled clearances rotate in opposite directions, driven by synchronized gears. As they turn, they trap gas between the rotor lobes and cylinder wall, moving it from intake to discharge without contamination.
