Typical Circuits and Accessories
To compress shop air or bottled gas to higher pressures, Sprague boosters are combined with accessories to provide complete circuits as shown below.
An air control unit and shut-off valve are installed in the driving air side of booster. Noise is dampened with a muffler. An air filter (10 micron) is recommended in the gas precharge line. On the gas discharge side, a pressure gauge, shut-off and bleed valves are installed.
For convenience, boosters combined with compatible accessories can be obtained as complete, ready-to-use power units.
