VEVOR PCP Air Compressor, 4500PSI/30Mpa Portable PCP Airgun Compressor - Built-in Water and Fan Cooling System, Auto-Stop | DC12V/AC120V Paintball Tank Compressor for Air Rifle, Scuba Diving Bottle

When you plug it in (120VAC or 12VDC), there is about a half second delay and the fans spin up. They are LOUD. My PCP has a 250cc tube and goes up to 250bar (3,650psi). I usually fill from about 1,800psi back up to 3,650. It takes about 6 minutes and shuts off automatically. I can't see what the water system is actually doing, but the temperature display has yet to go over 28°C during a fill. The room temp was 17°C. It took about a cup of 50/50 antifreeze/water mix to fill the system and I have yet to see any indication of flow even with the cap off. I didn't get an owner's manual in the box and their customer service, online got me an electronic copy in no time. So far, very happy.

I use this to fill by PCP pellet rifles, it's such a treat! I hated the time and effort it took to use the hand pump to fill them up, enough to where I wanted to consider not using them anymore. This compressor is amazing. Fills my tanks in less than 10 minutes. Doesn't overheat on me, feels safe to use. Of course it's a little loud but not bad at all. Love this thing!

So far so good I have only filled my 66cc tank maybe a dozen times to 3625psi but it has performed perfect every time. It is in my shop and the average temperature is around 96 degrees f and the compressor has not got above 38 degrees c only takes about 5 minutes from 0-3625 and about 2 minutes from 1500-3625.

I chose Vevor's highest-priced PCP compressor, hoping for years of use. Knowing that heat can be a major issue for these devices, I decided that the water/fan model was worth the extra money. I didn't want to spend double on the GX CS4-I, so I waited two weeks for it to be delivered, only to find it DOA. The packaging was adequate, and the unit itself looked really nice, but there were issues right away. The pressure gauge had a green marker with a wire attached that would move when adjusting the needle, and the needle ended up on the wrong side of the set needle. Unless the dial was turned all the way down, meaning there was no set pressure, the unit would instantly display an E4 error (indicating it had reached pressure). It didn't stop there. Within two seconds of starting the compressor, it showed an E0 error (temperature fault). I also had concerns when adding water, as there was already some water at the bottom, and it was starting to corrode. It's a shame because it looked nice, the fan sounded powerful, and when it did run for those few seconds, the compressor was decently quiet. If I could get a replacement in a couple of days, I'd try again due to the lower price compared to the GX CS4-I, but I'm not willing to wait another ten days. I'll also point out that the included manual had no directions on how to rebuild or replace any parts like I've seen mentioned on some of their other PCP compressors. The manual states not to open it as it is not serviceable.

Great PCP compressor for fair money. Directions are clear, step by step, comes with rebuild kit for the o-rings and filters. Hopefully it lasts a long time!

works great so far so good

Good 👌

Pump works as it should. But word of warning. The 4 screws that connect the pump to the motor started backing out shortly after i started using it. To the point that if i didn't intervene it would of damaged the unit. So if you buy one i suggest you keep an eye on the pump (visible through the grill) and if it starts moving and shaking around excessively. You will have to remove the cover (several screws and easy) then one by one remove each of the 4 bolts holding the pump to the motor adding Loctite to the bolts. Then screw them in evenly and securely. After i corrected this the unit is running better than ever.
