Omega or AirVenturi or Benjamin

OK..which would be a better deal ?

Please try to leave any animus about a particular dealer out of the discussion. ;-)

I'm only interested in the pluses and minuses of the tanks themselves. I know there are larger tanks available but have a friend with a compressor..so re-filling isn't an issue. It'll be used to stuff in a back pack for use away from the truck.. 

I guess the big question I have is how to compare the tank sizes..they all look/seem of similar dimensions. When I do the on-line conversion..18 cubic feet to cubic inches..the results seem really sketchy.

The Crosman re-fill calculator says 8 refills of the 350cc Bulldog, other calculator show approximately 3 refills for a 300cc air cylinder going from a 130bar to 245bar fill.

This would be to refill an Edgun R5 Standard in .30 and I'm not sure of the air cylinder volume..can't find any data in the user guide or online..but I assume is must be around 300cc.

They are all the same for the most part. Try to buy one with BOTH gauges. Tank pressure and fill pressure.

Thx for the feedback on the dual gauges. Makes sense. Looks like the AV tank is the only one with 2. Anyone have any experience with the Guppy tank from ExpertHPA ?

I had 2 Benjamin tanks. They looked nice but both were returned because of fitting leaks. The valve on the Omega looks like it is heavier duty/better quality than the valve on the AV unit, which looks a lot like a Ninja valve. The Omega Gauge is bigger, easier to read and probably more accurate than the smaller gauges on the AV. While it is convenient to have a separate tank gauge, you can also just plug your fill hose or cylinder valve with a deadhead plug and it will do the same thing. Also, if you accidently knock the tank pressure gauge off, you can have a real problem.

You might also want to look at the small Airhog tank: https://www.airhog.com/tank-sets/178-14-cuft-small-tank-set.html It has a valve made by Midland Diving, which is very good quality. I have one of these tanks sets and a second larger AV tank with this valve and it is really easy to regulate and bleed pressure. You can easily throw the small airhog tank in a backpack.

The other thing you may want to check is whether the valves or fittings are restricted. If your friend has an unrestricted fill set for filling the cylinder, than you can use a restricted valve and/or fittings on your set, which will make it easier to control the pressure when filling your guns. You can fill a cylinder with a restricted valve/fill set, it will just take longer and the compressor will have to work harder. Likewise, you can fill a gun with an unrestricted fill set, however, it will fill very fast from a 4500psi tank and will be more difficult to control.
