Material Conveying with Pneumatic and Vacuum Systems ...
In many manufacturing operations, a very significant compressed air use is pneumatic conveying of many types of materials such as cement, fly ash, starch, sugar, salt, sand, plastic pellets, oats, feeds, etc. Often these are systems that use highpressure air (100 psig class) reduced to lower pressures (15 psig, 45 psig). This creates an air savings opportunity.
