Compressed air isn't. There's not enough room in the an.


Druckluft 67 (aka Dust Off 67) from Kontakt / CRC says not to shake
the can "or otherwise the fluid might come out", but is it always the
case with all types? What is that fluid for, anyways?
The fluid evaporates, produces gas, and that's what your "compressed
air" happens to be.



I read reviews of some cheaper compressed air products on amazon and
they complained about the quality. What can go wrong with compressed
air?
Liquid for one, which you don't want, and then again, what's the
liquid that's evaporating to give you this "air"?

Two things people brought up were one brand produced very weak
pressure, and another produced flammable rather than inert gas.
Depends on what's evaporating. Butane would work, so would freon, so
would a lot of other things, includin propane.

Druckluft 67 touts as being oil free. Are there other things that
might go wrong?
er..... what's in that liquid?


Why would someone use canned compressed air rather than an air compressor?
Because they don't have an air compressor. Because they don't know
the difference. Because they don't have a "quiet" air compressor.
Because they don't have the driers and particle filters to clean up
the output air from the compressor (which may or may not have oil in
it from the air pump).
