Nice equipment but well the original post was about freezing electronic
component, and not to cool down dry machining operations.

For electronic application, the chemical used must be clean and not have
any contaminants in it, otherwise the electronic won't like it.
I see that Exair Vortex include a dust and oil filter but is it clean
enough for electronic parts ?
Another thing is that also it is small compared to a milling machine, the
Vortex is still quite bulky to use in a lab, specially with the hose for
the shop air.

Aother thing to consider is that most freeze spray are specified with low
electrostatic charge, because charge build-up could destroy components.

As for Bev Christian's concern about CFC, there are Freeze Spray without
CFC.

Hi David!

That's why this list is so valuable! They are still around!

Thanks!

 Bev, Years ago (about 7) there was a company selling hand held Vortex
 generators that plugged into 100 psi shop air.
 These little jewels put out -40 degree C air as long as there was 100 psi
 available. It also had to be dry nonlubed air. The company was called
 EXAir. I don't know if they are still around. David A. Douthit
