Chicago Pneumatic QRS Airline Regulator

The Chicago Pneumatic QRS Series is a line of airline regulators, designed with a knob adjustment that features a three position non-rising knob: push to lock, pull to adjust, and detach to make tamper resistant. The reinforced diaphragm allows for repeated accuracy. The compressed air control valve reduces compressor supply pressure to a recommended constant downstream pressure suitable for air tools. The regulators function by regulating air pressure in the air line at point of use and feature self-relieving style units.
