G SERIES
Air ring vortex wacuum pump
The G series air-ring vacuum pump adopts wide pressure double frequency 50hz-60hz.
Protection level IP54(insulation level F) motor features. This makes it the best solution for
the world. They can directly interface with European and American application standards
Total workCNC numerical control process and strict and accurate quality inspection process
are adopted to ensure that the positive and negative pressure difference exceeds the average level of the same industry by 30%. 
This makesthem the ideal solution for world wide use .

G_series operating principle
The impellers in the R_series machines are mounted directly on
the motor shaft for noncontact compression entirely without friction.
Maximum operational reliability, even at high differential pressures. is
ensured by the arrangement of the bearings outside the compression
chamber.
The gas it taken in through the inlet 1. As it enters the side channel 2,the rotating impeller 3 imparts velocity to the gas in the direction of rotation.
Centrifugal force in the imp eller blades accelerates the gas outward and the pressure increase.
Every rotation adds kinetic energy.resulting in the further increase of the pressure along the side cha nnel.
The side channel narrow at the rotor, sweeping the gas off the impeller blades and discharging it
through the outlet silencer 4 where it exits the side channel blower .
