Speedaire 4ZM08A Compressed Air Regulator And Gauge

Speedaire 4ZM08A Compressed Air Regulator And Pressure Gauge is a compact aluminum regulator with an integrated pressure gauge that provides precise downstream control for 1/4 in. NPT air lines. It accepts a 1/4 in NPT inlet and delivers regulated air through a 1/4 in NPT outlet, with a stated flow of up to 15 CFM and a regulation range of 5-125 psi, while tolerating a maximum inlet pressure up to 300 psi. A gauge port sized at 1/8 in NPT accommodates mounting a compatible pressure gauge for direct pressure monitoring at the regulator. The adjustment mechanism is nonrising, helping maintain the set pressure once it’s dialed in. Built from aluminum for light weight and corrosion resistance, the regulator offers a compact footprint with an overall width around 1-5/8 in, enabling integration with Speedaire FRL assemblies and panel-mounted applications. Typical uses include regulating pressure for pneumatic hand tools, spray systems, and other air-operated equipment in maintenance shops and light manufacturing where stable, adjustable pressure is essential.
