ReAir is a small
refillable version of
compressed air (by Read Right) designed to be refillable via hand pump,
air compressor, or a small
specialized air compressor (by Read Right, of course). The whole idea is that it uses plain
honest air (no
chemicals) and is
refillable, instead of
disposable cans that contain who knows what. The 5 oz. cans should be discarded after a hundred uses though, due to
moisture buildup in the can (accroding to R R).
The idea sounds
neat enough but the cans cost about $8 apiece, and the specialized compressor costs some $60+. For that price, you could get a big
air tank and a set of
nozzles from
Sears that would last forever and you could refill at
Quiktrip. We actually did this at a computer shop I worked at. The little cans will store up to one hundred pounds of pressure, but it usually isn't enough to blow out a very dusty system without a refill or three halfway through.
My advice: Save up for a nice air compressor.
