Principle of oxygen regulator: after the original high-pressure oxygen in the oxygen station or oxygen cylinder  is depressurized by the pressure reducer of the oxygen regulator, it changes from the original high-pressure state to low-pressure oxygen that can be directly breathed by the human body. After being regulated by the flow regulation part of the regulator, oxygen can be output from the output channel at a certain flow rate.

click-style oxygen regulators are designed for use in ambulances, hospitals, and portable hospitals and mass casualty situations . The click-style oxygen regulator is easy to use because you simply turn the click to obtain accurate flow setting. Unlike a traditional oxygen regulator, the click-style oxygen regulator does not need to be in an up-right position in order to function properly. This oxygen regulator is light weight, rugged, and has large, easy to read numbers and fits in confined spaces, we offer five different configurations 0-4L, 0-6L, 0-8L , 0-15L and 0-25L.
