The Arrow Pneumatics B742 is a compact miniature integral filter/regulator that combines particulate filtration with precise pressure regulation in one panel-mountable unit. Its relieving design holds a steady downstream pressure, and a three-position non-rising knob lets you push to lock, pull to adjust, or detach to make the setting tamper resistant.
