Back to the OP's topic, basically any air compressor under $1k is created pretty damn close to equal, find one that has cast jugs instead of aluminum and get an oiled air compressor vs an oil less so you can still hear your self think while it's running. A 220v unit will be cheaper to run if you have that option in your garage. And remember that extended warranties that are purchased thru the place of purchase, ie Lowes
, Home Depot
, TSC, are actually not warranties and in the event of breakage you will receive no warranty repairs from the purchase of it.
I just helped buy an IR compressor and the entire pump is cast iron. No aluminum. Fine that you refuse to sell them, and you have every right to sell what you want, and have your opinion. I have a right to my opinion as well and I love the IR compressors, and use them all the time with no complaints.
I would like to see some documented proof that they are Chinese built, as every one says built in the USA. For example this is the breakdown of the compressor I helped a nearby shop get for their paint booth:
•E-series motor starter (mounted & wired)
•Relief valve & discharge ball valve (mounted & piped)
•Air cooled aftercooler (mounted & piped)
•Low oil level shutdown switch (mounted & wired)
•Electric drain valve (mounted & piped)
•Automatic start/stop control with pressure switch
•100% cast-iron cylinders and pump
•Oversized cast-iron balanced belt wheel
•Oversized industrial-grade bearings
V-Block Deep Finned Cylinders
•Provides 360 degrees cooling for lower operating temperature
•Fully enclosed flywheel, belt and motor sheave
•All units are prewired and throughly tested prior to shipment
•Proudly built in the U.S.A.
As for what you said about the two CH pumps listed, both are showing in their spec sheet as "Solid cast iron oil lubricated twin cylinder pump" so I don't see how they could advertize them as such, if they had aluminum heads. Maybe I am wrong, but spec sheet agrees with my side. Of course the two CH compressors ARE single stage, so they have a lower pressure rating at 13PSI. I would always say get a two-stage compressor if you plan to do any REAL work.
