Compressed air acts as an energy source for a variety of tools and machinery, and it is often an important and well integrated part of many production processes. Compressed air is often used for blowing with air blow guns, air nozzles and air knives to to generate movements and lifting, or to clean, move or cool materials.

Compressed Air System needs . Figuring the correct pipe size for your compressed air distribution system is an important task. Pipe that is sized too small can create big pressure losses and reduce operating efficiency. Replacing piping is costly. On average, 70% of a contracted piping job goes for labor and 30% for materials.
