RSV Vacuum Pump
 

Hey Wel  three lobes PD Blower are new series Roots type blowers. By CNC machine, we made precise rotors. Getting a perfect clearance to upgrade performance, lower vibrations and noises results a significant improvement compared to traditional Roots Blower of two lobes.
Traditional Roots Blower lubricate bearings and gears with grease and oil but Hey Wel design oilbath . It is very convenient to maintain and oil has a better lubricating effect than grease. So it could be a longer bearings and gears life.
