Campbell Hausfeld MP516803AV Mini Filter Regulator With Gauge

Campbell Hausfeld MP516803AV Mini Filter/Regulator with Gauge is a compact 1/4" NPT air-line combination that both cleans and regulates air for small pneumatic systems. It pairs a 5-micron filter element with an adjustable regulator and a gauge port to monitor output pressure, delivering clean, controlled air to spray guns, nailers, and other pneumatic tools. The gauge is included but ships unmounted beneath a soft cap, and the primary 1/4" NPT inlet/outlet connections fit standard air lines. The unit stands about 9.63 inches tall and is 2.25 inches wide and 2.25 inches deep, with a weight around 0.57 lb, making it suitable for tight workspaces. Replacement filter elements are available, and the gauge port is 1/8" NPT, with the gauge rated up to 160 psi for monitoring. This integrated FRL (filter-regulator) assembly is designed to install inline on a compressor line to remove moisture and particulates before the regulated air reaches downstream tools, helping extend tool life and maintain consistent performance in hobbyist and light-duty shop environments.
