repurposed cpap?
So, I have a couple of old cpaps stored up in my attic and was wondering if anyone has repurposed their old machine for something else. I was thinking along the lines of an air supply for a small air brush etc. Anyone done anything neat with their old machine?

I've used airbrushes and they require much more pressure than you will get from a CPAP.

Best re-purpose is to locate a charity that sends used equipment to third-world nations where it is very much appreciated. It will be your good deed for the year.

An old unit could make a great hose dryer without running up hours on your main unit.

It might provide enough volume for a small forge. Fancy taking up blacksmithing? It is on my list to make custom woodworking hand tools. Or maybe for a charcoal BBQ if you like Chicago style steaks.

I have used one for pumping cold air in a beer fridge from the evaporator coils into the tap tower to chill the tap. This avoids excess foaming from beer hitting a warm tap. Genius?

Actually I use a CPAP hose connected to a computer fan in a project box. A CPAP produces too much air volume when the circuit is open (no pressure).
