Using compressed air for cleaning - Oregon
The compressed air must be reduced to less than 30 psi at the discharge end of the nozzle. Let’s assume you are blowing filings off a bench grinder with an air gun and the pressure at the nozzle is 90 psi. Some employers think that the only way to reduce the pressure to less than 30 psi is to lower the compressed air line pressure below 30 psi

Air compressors typically have a “cut-out” pressure between 110 psi and 130 psi and a “cut-in” pressure about 20 psi lower. Air pressure build-up from 85 psi to 100 psi should take 45 seconds or less. While driving, observe the air pressure gauge

fisicaatmo.at.fcen.uba.ar1.2. Pressure Modeling To calculate the standard pressure p at a given altitude, the temperature is assumed standard, and the air is assumed as a perfect gas. The altitude obtained from the measurement of the pressure is called pressure altitude (PA). Both Table 2 and Figure 2 show variation of the pressure altitude as a function of the pressure.
