Combines filter and regulator into one unit to save space removes unwanted dirt and water particles Provides regulated output pressure of 0-125 PSI for proper tool operation The Campbell Hausfeld mini filter/regulator (MP516803AV) filters compressed air and allows pressure adjustment, removing dirt and water to extend air tool life and delivering the required air volume for proper tool operation. The sintered bronze filter element effectively removes contaminants as small as 5 microns while a self-regulating design vents downstream air for easier adjustments. A locking pressure knob prevents accidental pressure changes. 150 max PSI inlet pressure, 1/4 inch NPT (F) ports, 15 SCFM @ 90 PSI.
