do you ever wonder if the specs on tools are correct? are they what they say they are? well here is a good example of having to trust the manufacture. I have several “wheelbarrow“ air compressor. two small tube tanks with the pump and motor on top, and rolled like a wheelbarrow, and used mostly by contractors for portability. i have one brand that claims 8 gallon capacity, and another brand that claims 9 gallon capacity. i measured around the tanks with a cloth tape measure, both measure 18 3/4. measured the length and both measured roughly the same, 34 1/2. so somebody is lying, and i believe it to be the 9 gallon manufacture. and in doing some figureping with some online calculators, i don’t believe either would actually hold the four four gallons it would take to make eight gallons. then i measured a newer 9 gallon compressor from the same manufacture, and its tanks had the same measurement around the tanks, but they were 36 1/2 long. so if both claim 9 gallon, but one is 2 inches longer? hmm, i think the amount the tanks hold is like the horsepower ratings use to be on electric air compressor, some theoretical number. not to mention you have no way to know if the compressor puts out the cfm they say it does.. i have one that i am pretty certain is overrated in what they say it puts out, vs what my experience and some digging into the specs of the pump say it can put out. really doesn’t make a whole lot of difference if they hold 7 8 or 9 gallons, it still does the job just fine, just frustrating that you can’t get accurate numbers from the manufactures and they leave you to wonder. any thoughts or comments?
