Speedaire 4ZM23A is an industrial aluminum air regulator with a 3/4 in NPT inlet and a 1/4 in NPT outlet, designed to tame compressed air for high-flow pneumatic systems. It accepts up to 300 psi inlet pressure and provides an adjustable output of 5 to 150 psi, with a maximum flow rating of 220 CFM and a temperature rating up to 175°F. The nonrising design helps maintain steady output under varying line pressures, and it is commonly used as part of Speedaire FRL packages to supply controlled pressure for shop tools and other pneumatic equipment.
