Need advice on a used Air Venturi 100 cu in. Size 16” x 4.3”pcp tank

I purchased a new 74 cu ft tank from PA during their sale (got it last week.) After sale price & discount =$338.20 with
shipping included. They currently have a refurb DOM 3/20, 100 cu in. bottle, without discount at $279 shipped.
Make sure what size works for you, then be patient and keep looking. Lots more fills from a big bottle, Small is handy.
 
You will likely only get about 3-4 fill ups out of that bottle on that rifle. It would be good for a short shooting trip or hunting trip but I would suggest a larger bottle like a 74 or 88 if you plan to do any more shooting than that.

More like zero re-fills. Using the AoA calculator page, an 88 cubic foot tank filled to 4500 psi will only give you 2.6 complete fills if you have the dual 1700 cc volume tanks, refilling from 1800 to 3600 PSI on this gun. From 2200 to 3600, you will one more fill at 3.1 fills.


The AEA website says the operating pressure is 2200 to 3500 psi. I don't know if that means you want to refill at 2200 or not or how low you can go with full velocity. If the OP has the latest gun that has dual cylinders (one 700 and one 1000 cc cylinder) totaling 1400 with 2x 700 or 1700 ccs volume with the 1K and 700k, depending on which configuration you ordered. What I was not able to find is the compressed air capacity of that 100 cubic inch VOLUME tank but it is tiny compared to the 88 cubic foot compressed air capacity tanks which have a VOLUME of 550 cubic inches, more than TEN TIMES the internal volume of that 100 cc. (Remember the volume numbers are not compressed air capacity!)

100 cu in isn’t going to go very far. For a first tank / primary air source it isn’t a good option in my opinion. Buy the 74 cu ft tank.

Agreed. The 74 cu ft is probably the smallest you would want for this gun as you might not even get two fills off a 74 cubic foot tank if you are refilling at 1800 up to 3600 psi with the dual 1700 cc combined volume cylinders. Filling from 2200 to 3600 on the 74 would give you about 2.6 fills.

As a comparison with an 80 cubic foot tank, filling the 1700 ccs from 2200 to 3600 psi for a 500 cc cylinder will give almost 9.5, almost 10 refills. With a 74 cu ft tank, 8.8 fills.

I would get the biggest tank(s) I could justify the cost for, keeping in mind that I would have to lug them to the range and back. particularly if I was paying to fill it. But of course I would not even consider paying to fill a tank that large that would be empty in less than 3 fills. I would be filling it myself. If I had that gun, I would probably buy several used 60 min / 88 cu ft SCBA tanks at $50 to $90 each rather than a single 100 cu ft at $700 to $800 each.

I stand corrected. The AEA I have is the smaller single bottle so I was basing it off that. I must have glanced over the model he had and just went off my own assumption. It would act as a little boost for bench shooting I guess but you are correct. Thanks

Welcome. Still no word from the OP on which tank sizes they have. What caliber AEA do you have and what is the capacity? I am very interested in a 35 cal semi auto but wish they had at least a 20 round, preferably 30 mags!
