A fan does not provide compressed air, it provides flow. That is why it is very difficult to even find a rating for delta P for most muffin fans as supplied in the KOP in the past. But I was able to find a rating for for a special "high static pressure" muffin fan for restrictive computer cases. This "high static pressure" fan was able to create a static delta P of .002 PSI when dead-headed.

Fans are listed in the rules under the electrical rules, not the pneumatic rules, for the excellent reason that they are not pneumatic devices.

The Q&A cited earlier was a question about using air from a solenoid valve attached to the pneumatic system, not a fan.

If you are not a member of the GDC, do not cite your opinion as fact (note that I have taken my own advice).

Here is what OSHA says... Compressed gas is anything over 40 psi. I seriously doubt if they got over 10 psi.
