ARO Pneumatic P39454-610 Pneumatic Filter Regulator

ARO P39454-610 is a 3000 Series piggyback filter/regulator that combines filtration and pressure regulation in a single 3/4" NPT body, designed to protect downstream pneumatic tools by removing moisture and particulates and delivering a controlled output pressure. It uses a 5 micron filter element and a metal bowl with sight glass, with a manual drain for maintenance, and it supports an output range of 0–145 psi (0–10 bar) with a maximum flow of up to 236 SCFM (111 L/s). The unit measures about 13.64 inches high by 3.54 inches wide (346 x 90 mm), and its piggyback mount fits alongside other filtration components in compact air systems. Common applications include protecting pneumatic actuators and tools in industrial automation and manufacturing lines where clean, regulated air is essential.
