Two-Stage GWV series
Two-stage GWV series
Feature：
1.Suitable for vacuum extraction of moisture, vapors, condensable gases and particulates.
2.The compressed heat was absorbed by sealed fluid, equivalent to isothermal compressing, thus cause lower temperature of discharged gases and ensured high safety for explosible gases.
3.Due to no metal friction in internal, thus no lubricant is needed; totally pollution free and low maintenance cost.
4.An additional atmospheric device (air ejector) is installed at the intake port, the ultimate vacuum can reach to 6~2Torr; series connected with a mechanical booster pump can conserve energy and increase several times of pumping volume and ultimate vacuum.
5.A noise-free, gas liquid separator can be installed at the exhaust port.
