My old 3 gallon compressor needs replacing. I want to go larger, probably 21 gallon. I have noticed oil lube compressors are less expensive than oilless compressors at similar PSI/CFM. Advantage/disadvantages of each type please.

[image] George_San_Jose1: when you want to do a high quality spray paint job and don’t want oil from the compressor to contaminate the paint finish appearance Not really true since body shops use industrial sized oil type compressors. You just add oil-separators inline or in my home-use case…

Yeah I’ve got the in line filter but I always also just used a filter that attaches right to the spray gun as a final filter. I never really noticed any difference in the oil bath or oil less, except after taking one apart, the oil less is pretty much a disposable compressor. Still it fits my need…

I imagine SBD will try to rebadge their tools that could be sold at a Craftsman price point, like Stanley hand tools, some BD power tools, some Porter Cable equipment, and Dewalt power tools. It was shown long ago that if you are going to lose business to another brand, you might as well own that br…

Does anyone have a suggestion on preventing rust in the tank?

Drain it daily. If you don’t use it for a long time, leave the petcock open. Speaking of petcocks, make life easy on yourself. Get an NPT elbow, extension, and ball valve and replace the petcock with it. Like this: http://revlimiter.net/blog/wp-content/uploads/2010/05/DSC_6446.jpg You’re much mor…

I’ve wondered if frequent draining of the tank really does much. A little water always comes out of my old Craftsman. But, it seems to me there’s always some water in there, right?

[image] [image] That’s an air tank that had a leaking drain petcock, so the brilliant owner decided to remove the petcock and replace it with a plug. It was then used for a number of years without ever draining it, because it couldn’t be drained. The bottom of the tank rusted from being wet all th…

I’ll eat my words if need be but I find it hard to believe that 100# could blow a tank apart that bad. The other day I popped the release valve at 120# and outside of a pretty good stream of air, not much there there. Also if a tank is rusting, wouldn’t it tend to form a rust hole so it wouldn’t h…

[image] bing: wouldn’t it tend to form a rust hole so it wouldn’t hold air rather than rusting the whole tank to the point of catastrophic failure? Usually, yes, that’s how it happens, and you hear the hissing and know you need a new tank. But there’s always that rare instance when the norm d…

I used to drain mine but it was a hassle and I’ve found the tanks last longer than the compressor. So I just have a water trap to keep the lines clean.
