I just completed the first running of my new Air Venturi compressor from Airgun Depot. After putting in the 5w-40 oil and filling the water tank with distilled water, I proceeded to run the unit unloaded for the prescribed amount of time. I already had a Joe Broncato moisture filter which I hooked in line between the compressor outlet and my 74cuft tank. After the break in time I closed the bleed valves and opened the air tank inlet. I had been used to the Shoebox taking quite a while to fill my tank. I topped my tank off from 4200psi to 4500 psi in 10 minutes. Looking forward to first full refill. I was glad that the shut off is able to be set a bit over 4500 to be able to get a full tank. Sometimes scuba tank stores only fill to 42-4300.

Sounds good... One thing I do recommend is not opening your air tank inlet valve until compressor pressure is close to the air tank pressure when topping off.

good point centercut.
Jland48 why did you use 5w-40 oil? I dont remember seeing that in the manual. Why not just use compressor oil? Im just wondering. I used a regular compressor oil for a few hours and changed the oil to a synthetic compressor oil.

The book with mine says 5W40 or compressor oil. I understand /am told Ingersol/rand synthetic compressor oil is the best for them. I'm switching to that on my next oil change. Brian Smith

Royal Purple synthetic "compressor " oil? I musta been under a rock. I thought you were saying just royal purple synthetic and I thought it was auto/truck oil. Brian

I am having a hard time changing my mindset from air miser to all the air I need at my control. The compressor seems to be very well built and I intend to change the oil very regularly. I noticed no discoloration of the oil in the time I ran the unit. The Temp. only reached 62c. I now am wondering if I should put my Shoebox up for sale.

Me too Imold. I just broke down and ordered a 98 cu ft air venturi tank last night. Cant wait to get it and fill it at home with my AV.

I had a meeting with an oil specialist today and inquired weather 5w-40 or compressor oil would be better for my AV compressor. He told me that 5w-40 motor oil is loaded with additives that are not needed and could be harmful to a compressor. The additives are intended for automotive conditions and when subjected to the compressor chamber and no combustion could drop out and form deposits in the area where the air is being compressed. Compressor oil however lubes the rings and crankcase only. He also said that it should be cheaper than motor because it cost less to make, but we know that isn't true. So I am going to drain my AV and put in compressor oil.

Got some RP coming from Amazon... I plan to try that and the IR I have on hand. Thanks. Brian

I totally agree. Try something if you have an AV or similar. Once it’s been running and filling a tank under load, say at about 4,000 psi, reach down and feel the temperature of the crankcase both on the lower sides and bottom. You just may be surprised. Unlike a car engine, the oil in the crankcase of the AV gets warm, but not hot. Mine is warm enough that I can easily keep my hand on the crankcase housing indefinitely without discomfort. So you can see that the compressor oil is designed for conditions much different than a car engine.

I'm really very surprised that the AV instruction pages would say what they do. I talked to Jordan the head compressor guy on the phone at AV and I was left with the feeling just about "any" oil would work. That is why I originally went with the Campbell Hosfield oil. Brian Smith

Brian: Yes, but these are the same guys that say you can run it at 75C, that 80C was no big deal and don’t worry, it’ll shut itself down at 95C. These guys are probably not mechanical engineers, maybe even not any kind of Engineer. My Tuxing rarely gets over 60C, and only when it’s warm in my garage and I top off more than one tank. Even then it steadies out between 60C and 65C, and that’s running it under load without stopping for over 1/2 hour. Will it run at 80C? Yes. Will it last long running it at that temperatue? Probably not.
