Got one of these all in one little $300 orange pumps. Quieter than I expected. 3 fills from 130 to 250 bar so far and no problems filling the 580cc tank. Takes about 5-6 minutes at 55 deg in my shop. Digital temp gauge gets up to 27 C so that still pretty cool for an oil less water less rig. Only 15C temp rise over 6 minutes. 

I will try to get back from time to time and report on how this thing holds up.

That style of compressor does seem to have durability problems so do keep in touch. They are rated for 20 hours of use before a rebuild from what I have read. Heat is it's #1 enemy. So, be kind to it and don't overheat it to make it last.

Never try to start the pump against pressure in the hose. Been there and broke mine like that.

Shoot'em good!

I'm inclined to believe that many of these compressor failings are due to operator error. I did a few break in runs with just the fill hose on and let it rest and cool in between. Went from 100 bar x2 then 200 bar x2 and 300 bar x2. All these runs were just short of 1 minute. Then I removed the fill hose and changed out the filter cartridge. Since I don't fill past 250 I think I have met the pressure test. On the test runs I found no dirt or debris or any moisture in the filter that may have been left in the system during manufacture. Till next time.

So far all good except for using it thru the 110v inverter outlet on my Silverado pickup truck. Inverter outlet just does not have the juice it needs to keep the compressor running once it starts to build any pressure at all. I have not tried to use it with the straight battery cable connection. I usually refill when my bottle gets down to 140 bar. From there to 250 bar takes about 8-10 minutes and the auto shutoff works perfectly so far. Digital temp gage shows about 37C after 10 minutes compressor run time.

Update and knock on wood. Probably 30+ fills and the pump seems to be as strong or maybe a bit stronger on every fill. I only fill to 250 bar on a 580 so it's not really working it that hard. Have only changed the filter once and observed some faint orangish residue on the pump side of the cartridge. Digital temp gage never past 34c

Good luck getting parts, when time comes to rebuild. I have one there oil & water cooled unit & I,m looking to buy another compressor.
