How do Sprague gas boosters operate?
The Sprague gas booster is a piston-type, air-operated booster. It uses a mechanically operated, snap action air selector valve to cycle the booster. The Sprague gas boosters, like the Sprague pumps, employ the piston differential areas principle….a large area air piston, driven at low air pressure to drive a small area compression piston which converts input gas to higher pressure, lower volume gas output.
