Air compressors - help?, an education Options

[VaccaRabite]

So I went to Home Depot today, armed with some scratch and the will to buy an air compressor and a DA air sander.

HD sells the husky line. So, I went to the tools, found a DA sander (Husky, needed 4cfm @ 90psi, and the box said it would work continously with 20+ gallon compressors).

Then I walked over to look at compressors. They had a Husky 24 gallon compressor that flowed 5.1 cfm @ 90 pis on sale ($225). Score! but then, on top of the motor, was a little chart with reccomended tools and non-reccomneded tools. All sanders and DA sanders were non-reccomneded.

I called over a HD floor guy, who called over another 2 guys, and we could not see a good reason for the prohibition. But, we decided that if the factory did not reccomend it, then it should not be used as such, and I walked over to the electric tool section and bought an electric DA sander.

I am going to need to buy a compressor by the spring. I'm clearly in the "hobbiest" catagory, and may not use the tool again for a long time aftyer I am done with my 914, but when it comes time to paint, it will probably be cheaper for me to buy one then rent one - given the slow nature that I work. I want to know why the sander was not reccomended, when the compressor could flow the air and had a big enough tank according to the tool. I have theories, but I thought somone here might be able to give better advice.

Thanks

PVC pipe not to be used in compressed air systems

OLYMPIA -- The Department of Labor and Industries warned today that plastic polyvinyl chloride (PVC) pipe cannot be used in compressed air piping systems without the risk of explosion.

When PVC piping explodes, plastic shrapnel pieces are thrown in all directions.

"We're seeing more incidents of explosive failure, and we're citing more employers for using PVC air system piping," said Paul Merrill, senior safety inspector in L&I's Spokane office.

"It's probably just a matter of time before someone gets seriously injured in one of these explosions unless everyone pays more attention to the manufacturer's warnings," Merrill said.
Last year, a section of PVC pipe being used for compressed air exploded 27 feet above a warehouse floor. A fragment of the pipe flew 60 feet and embedded itself in a roll of paper. Fortunately, nobody was in the area at the time.
A PVC pipe explosion in a new plant in Selah broke an employee's nose and cut his face.

PVC piping buried 3 feet underground at a Yakima manufacturing plant exploded, opening up a crater approximately 4 feet deep by 3 feet across.

back to your question most paint guns that are not name brands (spendy) are chinese knock offs. i have four binks knock off in service for the last five years.and i will retire them after the the end of 06.with flawless service. as far as the compressors avoid the oiless ones there junk.
