Parker's P3YE is a particulate filter/regulator that provides accurate pressure regulation and high moisture removal efficiency in a compact package. P3YE is a one piece combined filter/regulator which minimises space and piping by incorporating two units into one. The P3YE is designed to provide quick response and accurate pressure regulation for the most demanding hi-flow industrial applications. The rolling diaphragm was designed for long, trouble free operation and will not rupture or tear under high cycle or other demanding applications. The P3YE is also specially designed to efficiently filter out rust, dirt, moisture and other impurities from compressed air lines. Operation is fully automatic with a minimum of pressure drop.
