2XZ Dual Stage Rotary Vane Vacuum Pump

● Due to the thorough low noise design and precision machining, so as to achieve low noise. ● Specially designed gas valve is prepared to prevent the pump oil from mixing with water and prolong the service time of the pump oil. ● Adopt similar product design, small size, light weight, low noise, easy to start. ● Equipped with vacuum drying oven, freeze-drying machine, printing machinery. ● It can be equipped with small-caliber adapter, KF interface and flange interface. Air Inlet Adapter The gas enters vacuum pump through here Air Outlet After the gas pumps into rear chamber, exhaust through here Gas Ballast Valve To prevent the pump oil mixed with water, when the relative humidity is high, can open the valve for purification Oil Filter Vacuum pump oil pour into Oil Meter Shows the vacuum pump oil level in the pump chamber
