However, in situations such as road or building con- struction, the level of airborne dirt may be extremely high, Figure 16-3. Preventing dirt from entering the pneumatic system is essential to the service life and performance of the total system. Dirt allowed to enter a system pro- duces unnecessary component wear. It also leads to the to provide air that is as clean, dry, and as cool as pos- sible for the location. Intakes should be: • Located away from dust-producing conditions. • Shielded from the weather to eliminate the entrance of rainwater. • Protected from direct exposure to sunlight. Direct sunlight can signifi cantly increase the intake-air temperature. B A DeVilbiss Air Power Company Figure 16-3.
