What is an appropriate application for compressed air that is less than 30 psi?

The application of compressed air that is less than 30 psi is best suited for cleaning work areas. At this lower pressure, compressed air can effectively be used to remove dust, debris, and other contaminants from surfaces without causing damage to the materials or creating hazards. Using compressed air at this pressure for cleaning is both safe and effective, making it a common practice in various industries and maintenance environments.

In contrast, operating pneumatic tools generally requires higher pressures to function correctly and efficiently. Inflating tires also necessitates higher pressures and is typically outside the range of 30 psi for most vehicles. Filling hydraulic systems requires specific pressure levels, usually much greater than 30 psi, to ensure proper operation of hydraulic machinery. Thus, the application involving cleaning work areas aligns perfectly with the safe operational limits of compressed air below 30 psi.
