We are offering here the Oxygen Regulator of various types that is a pressure regulator used to control the PSI (pounds per square inch) or flow of compressed medical oxygen from a tank to a medical device such as a flow meter. It releases compressed or liquid oxygen from an oxygen tank in a continuous mode measured in liters per minute (LPM). The regulator is a pressure reducing device that lowers the pressure of the oxygen from a cylinder to a level that can safely be used. The regulator is very accurate and made for medical facilities.
