I don't even want to comment having had zero issues with mine and the dreaded jinx. Have not changed oil or filter yet. 10.5 easy hours on the meter. Most of the time I only fill to 3000 since I shoot about 20' from my compressor. I pumped the tank up to 4000 a couple of times to travel and have ample air and I was surprised at the added time/heat in getting there. I don't think that's inherent to AV compressors, just the physical process in general; the higher you go the more strain there is.

Hoping that I keep having good luck. My Joe Brancato inline regulator will be here tomorrow or Saturday. Looking forward to getting that integrated and that should only help me manage my air usage, even if in a small way.

I have zero expectations for my $200 Yong Heng in terms of longevity.

I think the lower cost of the two Daystate compressors built for them by Coltri might very well be worth looking into.

Not much more than a full house Carrette, and have been building compressors for the Dive industry, and  used world wide for many years.

No surprise there .... HAVE YET to see any of these chinese HPA compressors that have come to market these past 3-4 years now survive to be deemed long term reliable.

Personally own one of the ALPHA 90's that is just about to make it 3 years. has a very bad rod knock and at last reseal had wear & tear showing that it simply IS NOT going to allow a whole lot more use before it is 100% garbage.  This inside 200 hours of actual use.

SAD !

Maybe I should knock on wood, but I have about 60 hours on my Omega Air Charger without a hiccup.

Although the unit supposedly requires 110 volts, the truth is here in Roswell, the nominal line voltage is 124. On the heavy-duty, dedicated, 20 amp circuit I have the Omega plugged into, the voltage drop when running is only 2 volts. I suspect some folks end up plugging theirs into a nominal 15 amp circuit wired with #14 where the voltage drop would be considerably more. That equates to a shortened life.

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

The "Alpha" is just the uncased version of the air charger.  My first reseal was required at @ 85 hours.  In that time went threw 3 of the final stage check valves which were easy enough to R&R.

The air charger is the same as the alpha, open design. I have about 22 hours on my air charger and so far no issues. Knock on wood!

Low voltage would explain electric drive motor failure. However, this in not what is happening. Itis rod/crank failures. I suspect that much like the 200-400 chinese compressors, that there is no bearing there. Only Alu. on Iron. A recipe for failure!

Lawnmowers (and many other small 4-stroke gas engines) quite often use an aluminum connecting rod on steel crankshaft.... and they run for decades....  ::)

The sound of a good rod knock is like victory.   8)
