Watch how it works

Perfect for developing, testing and diagnosing pneumatic equipment, the Proportion-Air Supply fits onto a laboratory benchtop alongside other equipment like power supplies and oscilloscopes. Executing burst tests, creating flow curves and calibrating air-piloted regulators are just a few of the applications this rugged device can accomplish.

The compact, all-in-one unit replaces the need for separate regulators and flow gauges attached to needle valves, a common setup for pneumatic testing. Each device includes two channel options. One output channel is solely for pressure regulation, ideal for simple testing processes. A second channel regulates flow or pressure at the same time, similar to the way a variable DC power supply regulates voltage or current. Easy-to-read digital panel meters show the pressure or flow being achieved, and LED lights indicate power and when the desired pressure or flow has reached its setpoint.

The Proportion-Air Supply works with shop air and instrument air. See below for additional specifications.
