What is the Amerex 10915?
Amerex 10915 is the Argon pressure regulator listed as item 4 on page 23 of the Amerex Portable and Wheeled Parts Book, PN 27277 Rev D. It reduces the pressure of the 110 cu. ft. Argon cylinder to the operating pressure of the Amerex 680R (150 lb Sodium Chloride) and 681R (250 lb Copper) wheeled Class D extinguishers. Amerex publishes a static dead set pressure of 120 plus or minus 10 psi and a minimum flow pressure of 110 psi for the Models 680 and 681 regulator, and notes that NFPA 10 requires regulators on wheeled extinguishers to be checked annually against those figures. Regulators cannot be field adjusted and must be replaced if found out of tolerance.

Can the Amerex 10915 be used on other Amerex extinguisher models?

Annually. Amerex's manual cites NFPA 10, which requires regulators on wheeled extinguishers to be checked each year against the manufacturer's dead set and minimum flow figures.
Can the Amerex 10915 regulator be adjusted in the field?
No. Amerex states that regulators cannot be field adjusted and must be replaced if they are found to be out of tolerance, which is why this part is stocked as a replacement.
