CHINA 4500 ELECTRIC AIR COMPRESSORS

They work well, I bought my a year and a half ago and still going strong, the oil I have been using on my is 5w/40, as said do not let the temperature hit above 60*c otherwise it will heat up the pressure rings and minimize the life span of it, after a year, I rebuild my with the spares that came with it. You can also fill your rifles straight from it, just keep an eye on the rifle's gauge, for the bottles, fill them with intervals, let the comp rest a bit in between that it will also save the life span of it. Also you can install a inline water/oil separator to avoid any to get into the bottles/rifles.
Here is a number of one of the consultants of the manufacturer, anyone can whatsapp her, she's a really nice person and answered all my questions about the compressor and she speaks English very well.
