    Rotary Vane Vacuum Pump Details Introduction

    Tips: 2-Stage Rotary Vane Vacuum Pump

    Two-stage rotary vane vacuum pump’s working performance is made up of the high pressure stage part and low pressure stage part; its air inlet port is connected to the vacuum equipment, and when running, a large number of gases in the container is sucked and discharged. When the equipment obtains vacuum, the high pressure stage exhaust valve will close and high pressure gas will be transferred to the second stage, and after the secondary suction and discharge, the vacuum equipment can obtain a certain vacuum. The 2-stage rotary vane vacuum pump features high speed, small size, compact structure, convenient to carry, which can be used for electric vacuum device manufacturing, thermos flask manufacturing, vacuum welding, printing, blister, refrigeration equipment repair and equipment supporting. Because it has the advantages of small size, light weight and low noise, it is more suitable for use in the laboratory.

    Super rotary vane vacuum pump!
    I have to be honest I was a little hesitant to order this vacuum pump because there is no rating here. Fortunately, it is a good deal. Easy to use well packaged unit, came with oil and easy to follow directions. Would recommend this unit.
