Compressed Air Safety - Quick Tips #187 - Grainger KnowHow

Q: Can compressed air greater than 30 psi be used for industrial purposes? A: Yes. Most pneumatic tools, including air guns, require 80-120 psi to operate effectively and to do useful work. However, they must have a relief device or air port within the system that will drop the pressure to under 30 psi if the air system becomes dead ended.

Air Flow In A Cone Shape - lasopaskill

The table shows: 1) How high air velocities greatly increase the pressure.When the air flow rate is raised to 1920 cfm, the velocity through the duct about doubles and the pressure increases 3-1/2 fold. 2) The system effect of having 2 elbows close to each other and being close to the hood. Using the pressure gains for 1000 cfm flowing through the system, we see that the pressure gain for the ...
