>>6318580>It's a general purpose model 459A blower
A quick search shows that it's a mains powered blower. If safety is a concern then immediately it should be noted that wiring mains electricity is very dangerous and much more likely to get you killed than DC 12V that you find with bilge blowers or server fans. And with a metal casing you must ground them properly. That's a huge concern right off the bat and if electronics were the hobby in question I wouldn't say anything but people just want to blow paint, not deal with hazardous wiring. If it's prewired then that's fine, but if it's not expecting uneducated people wire mains is a potential immediate hazard.
And if inWG is inches of water then a good bilge blower will maintain that airflow at a higher pressure from the spec sheets I'm seeing. If it's really necessary there are even squirrel-cage/blower type bilge blowers that will run on 12V at even higher pressures, though they seem to be rarer and will probably be even louder.
Also, I'm pretty sure even if it's "brushless" (couldn't verify this) an AC brushless motor would be different from a DC brushless motor just by virtue of AC vs DC operating differently. AFAIK DC brushless motors are more likely to be found in industrial settings where the safety might be needed so a DC brushless motor sounds like a safer choice over any AC motor, since it's just more reputable. >While I don't believe in going nuts with safety measures
Well besides just going overboard I don't think it's actually decisively safer. There are trade offs to go with a blower like that.
