1、The main body is aluminum alloy hard oxidation treatment, high strength, corrosion resistant. 2、High strength aluminium alloy material replace plastic bottle cap, avoid bottle cap aging. 3、Select all copper needle valve micrometering, accurate and stable. 4、Equipped with valve, pressure greater than 4KG automatic pressure relief, carbonated beverage bottle pressure 8KG, to use. The valve supports manual pressure relief. When the pressure is below 4KG, the pressure can be released through the pull ring of the valve. 5、Special pressure gauge: special pressure gauge with zone indication and scale! It is convenient to clearly observe the pressure of the start-up reaction and improve the success rate of the start-up; accurate pressure gauge, accurate to 0.02 MPa. 6、No- bubble counter: Internally designed check valve. 7、Micrometering valve, top open design, convenient to connect bubble counter. 8、Generator body: Aluminum alloy material, instead of the cumbersome air pipe, the pipeline is treated with corrosion resistance and acid and alkali corrosion resistance. Hard surface oxidation treatment, long life.
