Air Venturi Compressor

[StevenG]

Why add antifreeze?
I considered it might be for raising the boiling point but at 50% it would only add about 10 degrees and it reduces the specific heat.

Are you storing it in an unheated space?

[bnowlin]

I use antifreeze and purple Ice # 1 it was stored in on my back deck.  Now warm.  #2 To be honest with ya it just makes me feel better for lack of better reasons.

Thank you and yes I did use photo bucket. My favorite is of my son with the gun I sold.

Is that filter housing steel or alu, I'm kinda hoping its steel.

Well a magnet doesn't stick, it is panted black and appears to me to be a thick air craft alum aor painted stainless steel.

How do you know its aircraft alu? Not to doubt but the wall thickness looks a bit thin on the thread part. The filter tower is subjected to a lot of stress cycles and should be built accordingly. Going every time from 0-4500psi when filling.
On the antifreeze part, always use 50-50 mix to prevent galvanic corrosion between different metals.

I don't know that it is alu, it looks thick I have pmed our friend Tyler hoping he would chime in on that.  past the threaded plug it is pretty thick.  And I do use 50-50 mix and purple ice.

Yes, the housing for the output filter is aluminum. 

Bob, looking at the pics of your output filter, about how much use has that filter seen?

[bnowlin]

Tyler I have about 6 maybe 7 hours on that filter.  Weather has been so screwed up hadn't been shoot ing much.  Most of it is on the testing and review.  I really like it so far.  Pass it on if you like.  And I am sure that is Aircraft alum. right?  BTW how do you like the reviews?

Here We are years later and I just have to report on my AV 4500 and how bad arsed this thing has been!
Matt (insanity) can back me up on everything I post here incase anyone wonders.

I got mine back around October 2017. When they were $1200 delivered. I used a good oil and added Royal Purple to the water coolent system.

In the years since I got it? I've never added NOR changed the oil or coolant!
Not even the filter was changed!

Only thing it has ever needed was a battery for the temp gauge.

I kept it in the house up until a couple months ago. Today I moved it back into the house fearing the coolant would freeze.
It was kind of slushy but not a solid frozen block of destruction.

I'm gonna give it it's FIRST oil change and filter change along with a new mix of coolant.
So that's right around 6 years I've abused this compressor by neglect.

It has filled 4500 PSI SCBA and 3000 PSI SCUBA tanks many, MANY times. Not to mention Air Guns as needed.

So you can try to spank me for not doing regular service work if you wish.
All I will say, and others who have had access to this AV will say, is..........
It's a fantastic compressor!

[Insanity]

That compressor is a champ thats for sure.

Good to know!  My AV-4500 is still going strong also.  I always change the oil every six hours of runtime.  I use the Ingersol Rand all seasons select oil.  I also use 50/50 antifreeze and add a wetting agent.  It has never run hotter than 67°C.  I did replace the filter with the extra one that came with it.  The old filter wasn't super bad but was funky enough.  I'd have to check but think I bought mine in 2015.  I only fill a 60-minute and a 30-minute tank with it.  My .357 and .30 cal use a lot of air and I do a lot of tuning and testing.  This compressor has been awesome.  It has blown the burst disc two times (fun) because of how I used to use it.  I started utilizing the check valve on my Stikman fill assembly and all has been well since.

I really need to add a run time thingy to mine.

I really need to add a run time thingy to mine.

I've got an hour meter attached to mine, but I prefer to use a stopwatch and an Excel spreadsheet to keep up with the runtime and maintenance schedule.  I rarely ever look at the hour meter.  I don't trust it to be accurate and it is hard to read.  The stopwatch I can carry back to the computer and log when I get around to it.

[Privateer]

I'm not that dedicated as is obvious since I ran so long with NO maintenance what so ever.
 

But to be honest? I wanted to see how tough this compressor was.
It speaks for itself at this point in time.
