Q&A
Q: How do I know my regulator connection?
A: For the gas regulator, there are outlet and inlet connections. You can confirm the right connection size with your gas supplier.
Q: What is the maximum safe regulator pressure for oxygen use?
A: Depending on the size of the gas tank（oxygen cylinder) subsequent capacity may differ, but typically full pressure is about 2,000 psi and air pressure can go up to 3,000 psi. With the pressure in the tank, the Oxygen gas regulator reduces the supplied pressure to a lower, safer level for the user.
Q: Could I order according to my country’s standards?
A: DEM regulator design according to internationally recognized standards EN ISO, BSP, CGA, NFE, and AS. They are manufactured under the quality management of EN ISO 9001. DEM could offer the right type with the customer’s country standard.
Q: Could I use my brand and sticker?
