Questions about this product?

The Speedaire 4ZM14 Compact air regulator adjusts compressed-air pressure for the downstream equipment. It has 1/4-inch female NPT inlet and outlet ports and a nonrising adjustment control.

The regulated pressure range is 5–150 PSI; the 300 PSI limit applies to the inlet, not the adjustable outlet range. Select the regulator around the pressure and airflow your equipment requires, and include a compatible gauge when assembling the air circuit.
