    Just what the title says.  I have one, it's low hours (<10), nothing wrong other than the mess when venting and the smell after running it.  Just trying to get an idea of how long it might last.

    I had mine going on two years. Change the oil often and the filters when needed. Still running strong, knock on wood..

    Mine also smelled early on, but I notice it has greatly reduced. Currently at 19 hours.

    It may have been stated some oils may be less stinky than others.

    I've had mine for about 5 years, but easy local refills kept the hours down until recently.

    GeneT, I've had mine I guess it'll be three maybe four years this December, time flies by if you know what I've mean. What kind of mess is it making when you bleed it off. It should just be a whitish to clear dab of water. If its a black discharge of goo you have problems that need to be addressed. Just curios..

    White to tan and foamy.  It's not a huge amount – I put a shop towel folded in quarters under it to keep it off the floor (mostly).  I've never seen clear.

    If you plan on keeping this compressor, do yourself a big favor now and round up at minimum two rebuild kits and a bag of around 12 piston rings. It’s only a matter of time and it’ll be time to reseal and rebuild it. Not trying to be a downer, but if you do a search on this sub forum on failures on these models in just the last six months, you will see. I had a Lightning compressor from Hatsan which was close to the AV but with a few more bells and whistles, and right at 12 or 14 hours it needed a rebuild. Parts from overseas took 5 weeks to get to me. Hopefully your mechanically inclined and patient.

    Don't worry about being a downer, I very much appreciate an honest assessment, and you don't need to sugar-coat anything on my behalf.  I went into it half-blind, but understanding the risk I was taking at the time. 

    I have one rebuild kit, no problem with mechanical inclination – I have every tool in the book and a complete personal machine shop if I need something else.  Kinda waiting for it to die though, which would give me an excuse to get the Alkin or Bauer I should have bought to begin with.  (OTOH, I can't resist a challenge, so I'll have to resurrect it one way or t'other…)

    I've had mine since early June, daily I fill 5 252cc cylinders and 2 480cc bottles, sometimes more. I'd estimate 1/2 hour daily about 75 hours on it. I change oil monthly, Royal Purple. The only problem to date is that I needed a new water pump at 50 hours. Take care of your machine and your machine will take care of you.

    Hey GeneT, this is a survey of compressors I did a couple of years ago.  The data collection has languished (only about 20 survey responses in the last year), but I'd say the results are still valid with a total of 325 compressor reports total so far. 

    Here's the main list of compressor reports:
    https://www.airgunnation.com/topic/compressor-survey-results/

    And the AV report:
    https://ql.tc/mEaAh2 

    To your original question I have collected 28 responses for the AV compressor with the average number of hours being just under 16 (max=70 hours / min= 1 hour).

    Of these responses roughly 82% reported no problems (balance being about 18% who did have problems).  Of those who had shared their satisfaction with how the vendor handled the problem (4 responses) half were satisfied and the other have were "kind of" satisfied.   

    Again, most of these responses were collected between fall 2018 and fall 2019.

    Wow!  That's a fantastic public service you've got going there mcoulter!  I've only just peeked, but will spend some time pouring over the results.  Thanks for the pointing it out, as well as the effort to do it in the first place.

    AirVenturi was out of the AV4500 high pressure seals for a long time but Stacey recommended the Nomad II's seals since they had some of those and I think they actually worked better. My AV4500 is compressing better now than it did when it was new I think. From time to time I'll run a dead head test to 4000# and record the time. The last time after installing the new seals was 1min:45sec. In the past the best time was usually about 2min 15sec.
