First off, overall I've been mostly pleased with the performance of my AV 4500 110vac compressor after getting it new December 12th (delivered on the 19th) of 2017, which has 12hrs of documented run time. I'd consider it fast for topping off my SCBA's. Usually from 3100-3200 to 4400-4500 about 20min.
The first problem I had was about 6 months into it. The power supply that runs the cooling system went out. I called AirVenturi and talked to Jordan and he diagnosed it being that power supply. He promptly sent me another one and I installed it. Problem resolved.
The second problem started in late November (2018), still under warranty when it started producing a LOT of black oily fluids into the filter housing and at the same time the compressor would change sounds just for a second. It was still compressing well but I knew something was wrong. I contacted Jordan again and we decided to send it back in for repairs. This is why you want to keep your box and take care of it. Jordan found a broke high pressure ring which he replaced and he said he also found a leak somewhere on the hose that I wasn't aware of.
Turn around time was about two weeks when I received it back. Unboxed it found that the power supply cord and bleed screw were missing. The box had busted open on two corners so I was afraid the two parts had slipped out. I called Jordan and he had the parts. Stuff happens, no problem. About a week later I received the missing parts.
Thursday January 3rd I'm good to go. I get hooked up to my first SCBA start the compressor, sounds great, let it purge for a couple of minutes, close the bleeder and start pressuring up the compressor, filter housing and hose. It seemed slow though but I finally got it to within a couple of hundred pounds of my SCBA. I then opened the SCBA valve very slowly and equalized the two sides and started filling it. I started at 3200# and after 45min it had only increased to 4100#, hmm something not right here. I then just tried a dead head test of just the compressor, it's filter housing and the fill hose. This took 3:40sec to build 4000#.
I called Jordan and described how it was performing and he asked if I wouldn't mind pulling the second stage cylinder top off and looking at the high pressure piston. No problem, another learning opportunity I thought to myself. Not being sarcastic here I really wanted/needed to learn a little more about these machines. The top comes off very easily and here is what I found.
The bottom ring was broke and the middle had significant damage. I also inspected the cylinder bore and it shows some scoring but I don't know if that's normal or not. I also inspected the valve area and noted some pitting and a gouge very close to the high pressure discharge port.
I sent these same photos to AV and again visited with Jordan. He thinks the only thing needed will be the rings replaced and a cleaning and it should be good to go. AV sent the new rings and and a installation tool yesterday so I should have it in a few days. Hopefully I can get back to making some air soon.
Has anyone else had this issue with theirs? Just curious.
