The Cascade Effect: Filling your PCP Airgun Efficiently
When you bought your first PCP tank and used it to fill your PCP airgun, the world got a little bit easier, didn't it? No more hand pumping, plenty of air at your fingertips....you know, airgun nirvana!
At least until the air ran out, and then you had to go and get it filled again. And each successive fill after that was somewhat lower than the first once you got below the gun's peak pressure, right?
If you are lucky enough to have two airgun tanks, let me suggest a better way to stretch the interval between fillups of your air supply. It will save you money if you have to pay for a fillup, and time if you get your air for free. It's called cascading....
Designate one of your tanks as Tank #1, or "Initial Fill Tank". This is the tank you always use first. Attach it to your gun, and fill up the gun as far as the needed fill pressure that the gun calls for. Even when the tank drops below the peak pressure, USE IT ANYWAY. That's right, continue using the first tank for as long as you can, getting the majority of your air from that first tank. Eventually, you will drain Tank #1 down below the lowest pressure the gun will use, at which point you will need to have it filled back up. But in the meantime, what you've done is allow your second tank, Tank #2, to be the "topoff tank", and you actually use very little air from it until Tank #1 is way low on air.
This stretches the usefulness of the tanks because you aren't draining both tanks for complete fillups. You are just using the first tank, then "topping off" with the second tank. Your second tank will last a long time if you only top off the fill with it.
It takes a few extra seconds, maybe minutes to do it this way, but no one likes spending time at the fillup station....we'd rather be shooting!
I hope this little tidbit of advice will help you enjoy the sport of airgunning even more! And since you'll be shooting more with all that extra air, why not drop into the retail store here at Airgun Depot and pick up some more of your favorite pellets while you're here?
