Amazon PCP compressor.

I was informed about these awhile back but didn't run it until today. It's a $170 amazon Gina special, that comes with extra seals and o-rings as well as a water pump, a simple dryer. They say to use 5 gallons of water but I ran it through the chiller side of a water fountain I had.



Took two of my SCBA tanks, one from 2650 to 3500 psi and the other from 2700 psi to 3500 psi in 26 minutes, with swap.

It's got a cheap digital thermometer with a probe that inserts into the aluminum head/cylinder (it's two stage) they say to try and keep the temp between 50 & 75 C. Don't touch any of the stainless lines while running though.



Don't know if its worth the money but I have spent more for stuff that didn't last as long, already....

They do work quite well, but get a better water separator for it. The one that comes with it is not nearly enough.

And don't trust the guage or auto shut off.

The only other bad thing about it is that it is made in China, but I think nearly all of the PCP compressors are.

The YH is a common PCP compressor. Most seem to have decent luck if use scuba compressor oil (Seco 500) and change regularly and limit the temperature to under 120 degrees F:

Been running mine for a couple of years now with minor issues. I run chilled water and have an upgraded pump. It is known to use Water Wetter in the distilled water. I am afraid a lot of this stuff will become difficult to obtain, expensive and spare parts not so easy given the current goings on. Hope mine hangs in for a while longer.
