Industrial P29231-100 Filter Regulator 3/8 In NPT

ARO P29231-100 Filter/Regulator (Piggyback FRL) is a compact 3/8 in NPT inline assembly that combines filtration and pressure regulation in a single housing for easy installation on compressed-air lines. The unit accepts 3/8" NPT inlet connections and features a 6 oz (177 ml) bowl, paired with a 40-micron filter element to trap particulates before the regulated air leaves the unit. As part of ARO’s piggyback FRL family, it integrates filtration and regulation in one mountable unit, making it suitable for feeding pneumatic tools, cylinders, valves, and automated equipment with clean, controlled air pressure. The P29231-100 is commonly selected when a space-saving FRL solution is required on 3/8" lines, reducing the need for multiple separate components and simplifying maintenance by sharing mounting and service points with other ARO Flo products. Typical applications include woodworking shops, manufacturing lines, packaging machinery, and general automation where regulated air and particulate protection are essential for downstream actuators and pneumatic systems.
