Problem being that by the time you vent the cabinet properly, you have lost a great deal of the sound damping. It really needs to go outside in a shelter to cut noise level.
I have two small compressors and what Cyclotronguy says is a further enforcement of what I said.
IOW, for blow power you might as well get a Shop-Vac with a blower attachment. Cheap and with unlimited air supply.

Compressors in boxes are very prone to heat stress as predicted by "Gay-Lussac. Muffin fans and sound baffles, it's a very slippery slope.. If noise is the issue and a compressor is imperative mount the compressor remotely and run some plumbing to point of use. And while you're at it, use the gas laws to extract moisture from your compressed air. Store at high pressure, collect water...... use at low pressure
Actually to dust things off many times compressed air is the wrong idea! It certainly can move the dust, but all too often it forces some dust into tighter places where it normally would not go.
The best way to safely remove dust is with a brush and vacuum.
My other concern with a compressor system is the failure mode. Ever consider what will happen if the tank gets rusty inside and explosively fails. For my shop I placed the tank where I expect a breach to take out a distant outside wall.
Another issue is an airline should be continually pressurized. Taking up and then letting it bleed down stress the pipe joints and they will fail faster if the system is frequently cycled.
Then there is the issue of the pressure inside the pipe. Ever look at the pressure rating of pipes? Surprisingly low for some types.

Personally I wouldn’t want to aspirate the blow off. I just brush the alcohol and clean with a paper towel.
Not impressed with this thing at all.
Even with some heat shrink on the tip to narrow the air stream, it's weak compared to canned air or a typical blowgun on a compressor.
Oh, did I mention it's deafeningly loud?
Should have known better.
Second on Cal Air Tools we have a larger one than above inside our lab and its quiet for compressor. The bigger the tank the less it cyles. Build a surround, many designs on the internet.
Maybe this will do with a blow gun attached.

Not sure about the max 50 or so psi though, I'll have to check what we use at work tomorrow.

Use an old 1/8 or 1/10 fridge compressor, they are used with a filter at the inlet, and a regulator at the outlet.
Worn out ones are available in scrap.
Piston compressors put out 300 psi when new, and rotary models give 400.
Worn ones will still be above the 50 psi or less you need for air brush.

Air brush runs at barely any pressure, which is why I said use a regulator for control

The 30 PSI (2 Bar) is valid as a concern everywhere. Too much and you can have serious injuries from debris or even the air blast.
If the goal is to remove flux from PCBs, build the PCBs using solder with water-soluble flux. Then just wash the boards in warm/hot water and dry. I usually just shake the water off the boards, pat them down, and dry the boards in an 80ºC oven for a few minutes. If I use no-clean or RMA flux I use a flux remover followed by the same water clean.

Depends on the user, if you are using any tool, you must be aware of its dangers.
And how to avoid those, and take care of the tool, its maintenance and storage.
We had an incident recently, a lady worker's body wrap got entangled in a dough kneader, fatal head injury, she should not have worn it, or at least tied it securely (it is used here to cover the bosom at times, for modesty, with a Punjabi style Salwar Kurta dress).
And in all my years in industry, at least two deaths locally, as people put the discharge pipe of air compressors up their rectum, and turned the air on, for cleaning...ruptured intestines, painful deaths were the result. I am not making this up.
If the user is a Darwin Award candidate, stay far away, to avoid injury to yourself.
By your reckoning, a tire at 100 psi on a hauling truck is a hazard...and the units which inflate those.
How many accidents do you come across where people have been hurt by tires bursting, compared to the number of people using roads?

I use iso alcohol and a tooth brush to remove rosin core flux residue after soldering.
Then a wash with liquid dish wash soap, and a sun dry (we have strong sun most of the year).
No need for compressor, a blower is enough, and lots of cfm, instant as well, no pressure build up needed.
