Air tools rant

[deereman75]

Well here it goes. I had bought a Campbell Hausfeld DA air sander at home depot, to use for stripping paint, rust, and mill scale before welding. At the store it was listed as 10 CFM, when I got home and looked at the manual, it says it comsumes almost 20 CFM. I cant stand when they list the average CFM only, which is normaly at like 50%, especialy when it is a tool used constantly, like a sander. So I am taking the sander back today, and I hope they will accept it, as it was only taken out of the box to read the manual. It seems that the only air tools that are honnestly listed are industrial ones like IR and CP, if you buy a CP sander listed as 10 CFM requirment, it will use 10 CFM, not 20. I had also bought a die grinder at home depot, and it also draws alot more air then listed, but my compressor will still be able to handle it, at about 75%, so I will keep it.

I'm sure they will take it back.

I have a few air tools but find that even with my 5 hp compressor it is very inefficient, only get a minute or 2 at full power then the compressor comes on.

I know air tools are the industry standard for a commercial shop, but for the small shop I'm not sure. I use my electric 4.5 angle grinder for grinding, cutting and sanding. Never runs out of power.

I've got a nice Snap-on 1/2" impact gun and 3/8" ratchet from an estate sale but I rarely use them. I also have all the little air grinder gadgets.

CH air tools come in in a container from offshore.

That would give me a reason to upgrade my compressor

The other thing I hate is how places like princess auto say that air tools require a minimum tank size and hp, my 220v 3 running hp compressor with a 26 gallon tank will put out more air, at a higher duty cycle, then the 60 gallon compressors at home depot, with the 5 peak hp motors.

20 cfm seems like a huge amount of air for a DA. It seems like it would need 1/2" hose and that would be miserable to try and use with a DA.

I'd go to CH's site and look for specs.

 

[deereman75]

Those specs were from the CH manual that came with the sander, for 100% duty cycle. Anyways I am just leaving to return it now.

Do you mean from a place like Japan where all the Snap-on tools come from?

Princess Auto Supply? That may have been your first indication....:laughing:

What's that got to do with anything? The specs are written in english.
