HI you have couole of options but the wxd2 does not need that much air.
You can buy a 35l/min low noise for as little as €120 you have to find a company in your area.

Then add a pressure regulator, for the wxd2 set it to 5 bar which ismore then enough.
You actually on't need the 35l/mn because that would mean you keep the active button pressed, you only press it a few times per minute.
For 15 years now I use a compressor from an old water cooler that was scrapped out. It is quite and last forever, I have a gasoline fuel filter before the compressor to stop any solder etc. from the unit I change once in a while. It have been the best thing I have found. I also use a small cylinder for volume and a solenoid valve to go between the compressor and iron.
They are lots of them around and usually can be had free, or for low dollars.
Just a thought for you
Saw years ago when a shop used this system for 6 techs at a work bench.
It is very quite.
