    Oiless compressors have smaller displacements, so they spin the living crap out of them to get a decent CFM rating. And yes, they are deafening to be near. The difference is VERY noticeable. The oiless type are basically just an upsized version of those POS compressors that plug into a cigarette lighter. /forums/images/graemlins/eek.gif

    To the best of my knowledge (ok, setting self up for failure!!), the oilless ones use a teflon lined chamber. This allows for the piston to move without siezing up. They are normally cheaper and are considered disposable. I've heard of some people replacing the teflon insert, but I don't know for sure. The oil ones will typically last alot longer as long as you change the oil. I change mine once a year, but I only use it 8-10 hrs a month average. I bought the small vertical (26 gal I think) Husky AC & I love it. However, when I work on my trucks, I can only get 2-4 lugs loosened/tightened before the ac kicks on & I need to wait for pressure. I'm looking for a new larger one, but other priorities first.

    What difference does it make if your electrician can fry either one in 5 minutes? /forums/images/graemlins/yikes.gif /forums/images/graemlins/whistling.gif

    Unless it has its own insulated room, the noise is maddening. Mine does, and it is still anoying. I've had my Craftsman (5hp/25gal) for 6 years and it still works great, but if I knew then what I know now I would have spent the money on an oil type. All industrial types are oil lubed. My dad's had his normal (oil type) Craftsman (20gal/???hp) for over 30 years. The big one in his shop is much older, but its 3 phase and has a tank over 100gal. As always YMMV.

    I bought one of those back around '92 or so. After it finished filling the air tank the first time and finally shut off, I unplugged it, drained the air, and took it right back to Sears. /forums/images/graemlins/eek.gif I told them that the damn thing should come with "Hearing Protection Required" stickers! /forums/images/graemlins/angryfire.gif

    The next day I bought a Sanborn 5 HP dual piston oil-type compressor and it still works great. /forums/images/graemlins/thumb.gif

    I wish I would've had enough sense to do that when I got mine. I have a Craftsman 5.5hp, 33 gal and that damn thing is LOUD! Good thing it's about 75ft away from the truck, or else I'd be deaf...
