Air Products E12-3-NL45F Gas Regulator is a cylinder regulator from Air Products designed to reduce high-pressure gas to a usable downstream pressure, enabling safe delivery to downstream equipment. The model designation includes a 250 PSI rating, as reflected in the product title: Air Products E12-3-NL45F Gas Regulator 250 PSI. In line with Air Products’ regulator guidance, the primary function of a regulator is to lower cylinder or process-line pressure and it is not a flow-control device, so it provides a stable output pressure to downstream systems rather than regulating flow rate.
