Metal air flow adjustment vavle is preciser than normal plastic product. Cheap, simple to create pure CO2 constantly by chemical reactions. Our Special Advantages: 1.Blue transmission channel is made of PC material, solid, corrosion-resistant. 2.Air flow adjuster is dismountable to clean, cooperate with filter, can avoid damage caused by false operation. 3.Special transmission channel design can avoid aging(soft pipes are easy to age), and does well in leak-proof. Besides, you can clearly see the flow of liquid, watching chemical reactions at any time. 4.Not easy to accumulate liquid in the channel, make the most use of raw material. Note: 1.Don't open bottle directly when there's still on pressure, please wait for its automatic pressure release. 2.Please use food-grade citric acid and baking soda as the raw material. 3.For more specific instructions and usage, please read our English user manual. 4.The initial set of safety vavle is 4kg/c㎡, you can also adjust it manually.
