I would be concerned about dirt or at least dust blowing back out. IYou can also use a vacuum with the hose in the exhaust port i know the older
units can do this but alot of the new ones cant.
just peaceful how close you put the air stream to delicate parts.
and don't let the vacuum run to long so the air does not get to hot.
plan on using an air ball as soon as I get around to attaching the
fittings. I know of one place where I used to work that uses
compressed Nitrogen to make sure there was no oil or water
contamination. but I don't plan on going to those extremes.
