Longtech three lobes Roots Blower are new series Roots type blowers. By CNC machine, we made precise rotors. Getting a perfect gap to promote air performance, lower vibrations and noises results a significant improvement compared to traditional Roots Blower of two lobes
Traditional Pressure Roots Blower lubricate bearings and gears with grease and oil but Longtech's is designed to add oil only. Pressure Roots Blower is very convenient to maintain and oil has a better lubricating effect than grease. So it could be a longer bearings and gears life.
