If your application is for a room, a compressor is the wrong plan. You need
volume and slight pressure just higher than atmosphere. If you wish this air

blower is the answer.

Hi All
I assume it's not safe to breathe air from an oil lubricated air
compressor at sea level.
But does anyone know if it's safe to breathe compressed air from an
oil free compressor?
Thanks for your input.

Thanks for your thoughts, but my interest is more wide ranging that
just a room.
As an aside, your method is perfect for a conventional chemical &
silver photo darkroom. Most instructions tell the builder to suck the
chemicals out of the darkroom, but this has the serious side effect of
drawing in dust from everywhere surrounding the room. The noxious
fumes can be vented into a hood above them, pushed there by the
positive air pressure. If that's not enough, them they can helped
along by a slight negative air pressure at the vent, which might
require a slight increase in positive air.
