"Jim Wilkins" fired this volley in news:l16oh8$goh

The compressor guy in town told me the Teflon seals they use instead
of rings has a short lifespan.


I've never seen the advantage, anyway, except for tiny portable thingys
to blow up tires while on the road. Who needs a compressor who's not
willing to check/change the oil once in a while?

Even for medical uses, you still have to fully filter the downstream to
keep out wear particulates and condensed vapors from the environment.

For air brushing and other low-volume apps, they have (relatively) quiet
diaphram pumps. For HVLP, regenerative fans work fine.
