Can someone help me out here, what would a person need that kind of pressure for? Or is it a typo?
Yeah, you're right, those pressures seem way too high for compressed air! 4500 psi is definitely more in the ballpark for oxygen cylinders used in medical or industrial settings. Paintball guns and most SCBA setups typically max out around 300 psi. Unless there's some specific high-pressure air application I'm unaware of, it does seem like a typo. Maybe they meant 450 psi?
Air compressor?
