PA series oil less vacuum pump- Lithium battery industry- CNC machining

Project Introduction-CNC machining

Energy saving comparison between water ring pump and oil screw vacuum pump used in CNC machining center

Hanbell PA1300VSD + vacuum pump with 22KW motor

When the vacuum demand is reduced, the speed can be reduced automatically thanks to frequency converter, and the minimum load can be reduced to 5 kW.

 If the water ring vacuum pump with similar pumping speed is selected. It totally needs 5 sets with pumping speed 1600, and the power consumption is 45kw.

 Energy saving comparison: variable frequency screw vacuum pump PA1300VSD+ VS water ring pump
