Bull or fact?

chriscathro · 08-20-2012, 03:16 PM

I was talking to a guy this weekend who swore blind that he could fill his HPA tank using a hand pump, and that it does not take long (10-15 minutes). I took what he said with a very small pinch of salt but the notion has been playing on my mind. I did not get any details of the tank he has but I assume it is 20 oz. What is the general feeling about his claim?

Hello Chris,

There is truth to what you've been told but what he didn't tell you is that it takes a special type of hand pump to do this. These types of pumps are mainly used for "PCP" air rifles or Pre-Charged Pneumatic air rifles. The tank or air reservoirs for these have a smaller capacity than HP tanks used in paintball and has a limited fill pressure.

Well there you go then! I was thinking of using compressed are but what I read up on it said that unless you use breathing quality air you run a high risk of damaging the marker so I stayed with CO2. No breathing quality compressors where I am. These hand pumps from sears do not have filters by the look of them so does is the risk of damaging the marker really exist if non-breathing quality air is used?

What he's not telling you is how horrible his arms probably feel at the end of that pumping. I know one of the forum captains on the sight said he used one and it took three or four people and borderline sitting on the pump as they neared the max fill pressure.
As far as breathing quality air, any compressor that simply compressors the air around it is going to technically be breathing quality. You're not looking for scuba air quality. Same thing with this pump, it's just compressing the air it takes in.

And max fill is 3600 psi

Yea its a special product, you cant just use an old bicycle pump to fill 3000-4500PSI, I dont think you understand how much pressure that is. Also like others have mentioned its a pain in the *** to use, but it does indeed work.

There is a pump out there that can get you to 4500 psi which means around 4350 or so and it costs around $150/$180. IF you are thinking of getting one for tuning your marker get a refurbished 88/4500 or bigger if you can find it. www.swapmytank.com has the in the $120 range. Then you can get it filled at the field when your finished at the end of the day.

I bought the Benjamin hand pump for PCP air rifles, works great for my hpa tank, I was able to use it right out of the box no extra fittings or anything. At around 2200 psi it gets pretty tough, you just gotta take breaks every 30 pumps or so

tyronejk · 02-20-2013, 01:52 PM

I also have the Benjamin, and yes, once you get to about 1500 psi, you have to take frequent breaks. I'm guessing it takes maybe 1000 pumps or so to get to 3000 psi.

I just bought a axsor 3000psi pump of craigs because I was curious.
After getting the right fittings, I was able to pump up my 68/45 up to 3000

in about 45 minutes.
taking breaks to let the pump cool down to avoid damage to seals etc.

those seals need replaced about roughly ever 3-6 months. also make sure to check any filters on the pump that traps moisture/particulates. The pumps are a great idea but the time it takes, plus the fatigue, makes it not very efficient to fill our 4500psi bottles. It does work to get them up to 3000psi though, just takes some time and strength

Rob, when I finished pumping and released the bleed, water came out of a port at the bottom. I'm guessing that's the moisture trap, and I'm guessing that's a good thing yes?

not 100% sure. Ive seen some odd contraptions people are putting on those pumps, including fuel filters lol. Best thing to do is contact the manufacturer for your specific pump or possibly do a search on youtube to see if anyone has a video on how to make them work properly.

dapoofyhairdude · 02-20-2013, 04:43 PM

Hm according to a product manual for something that looks very much like my pump. the vent releases air as well as the moisture trap. I think that means I'm good. Also, you mentioned every few months I need to replace seals. If it's more than that period of time but not leaking, should I still look to replace them?

Edit, sorry for the thread hijack. But i suppose this is relevant....
