The reason the Alkins weigh as much as they do, is the cooling fin sections on the cylinder heads are solid cast iron. At least it is on my 2004 model they are. I’ve said it before and I’ll say it again, when the owner of airtanksplus who sold me this compressor made the mistake of shutting off the compressor at 4300 psi(when as I needed them topped off and it was also a tutorial on how to operate their Alkin), and restarting it WHILE THE COMPRESSOR WAS FULLY PRESSURIZED totally impressed the heck out of me. It didn’t stumble, cough, shake or fart. It just kept humming along like it was never shut off. Try doing that with the lesser priced models and see what happens.
@RANGUR1- I didn’t know you were looking at the Alkins as a future investment, you should’ve asked me when we chatted today. I’m not an Alkin rep, but what I do know is as of early 2020 the horizontal models like I own, are now equal in price as the vertical models. If I didn’t already own this horizontal 2004 version I’d get the vertical model as-
1. Footprint wise, it takes up less space than the horizontal unit,
2. It’s on wheels like a hand truck, so easy to maneuver if need be
Just this past month, I’ve assisted(or “enabled”, as DAVELARSEN called it, all in fun)two AGN members in solidifying their decision to go with an Alkin. If I remember correctly,one of them said shipped to his house it was $3200(that’s already with shipping factored in, at $3200) for the vertical model.
As far as noise goes, it gets clackety with noise at initial start up for a one second, then just purrs along like any other compressor made. It tops of my tank from 3200 to a complete full of 4500 in exactly 5 minutes each and every time. So, with that in mind, you don’t need to spend the extra for auto purge or auto stop. Filters and the special oil(DO NOT use Home Depot compressor oil, royal purple, or any of the ones used in the yong hengs) from filtertechs.com and a gallon of that oil at $75 will take you to your grave, along with the Alkin compressor as CRANK put it.
I tell everyone, it’s not a buy once cry once, it’s a buy once and smiles forever every time you flip the on switch, as you are your own air source.
Heck, if you got local airgunners nearby, charge them $10 for top offs and $15 for a 0-4500 fill on a new tank, and that’ll help offset the cost, and save them from paying crazy dive shop fill fees.
Pics of my horizontal set up-
I swapped out the cord end on the compressor to the same type shown in the pic, then purchased a #12ga, 25’ cord and cut off the ends and installed these 20amp, 220v terminals. Works like a charm, and from one end of my 32’ wide garage where the outlet is on the wall, I can wheel this cart all the way to the other end of the garage and the electrical whip on the Alkin along with this expansion cord I’m still easily within spec of the required amp draw so there’s no voltage drop.
