ok I just looked it up about 5.25x as long..theyll fill any size really, question is the time it takes lol i have a small one similar to it for sale, filled my 6.8 but took hours....
FX Impact M3 Sniper (580cc) 0-3625 PSI - approx. 16:05 min for that compressor, do the connversion to find ur cc for 3 liters and thatll give you a ballpark time to fill
My 1st pcp will be here Monday. According to what I've read it'll fill it in around 14 min. I'll probably just buy a tank and get it filled at a shop just in case I want to shoot a lot in one day.yea the smaller ones like these you shut down after like 20-30 minutes to cool off for like 20 min or something like that....they work great for intro to pcp or if you dont really want to spend alot. but after really getting into it, they arent worth it imo....pay for a decent tuxing or the nicer venturi =) my venturi fills 6.8l tank in very short order but it also costs more than most of my guns too lol
