pneumatics for featherweight

**Rahulvyas** · 29th October 2013, 00:13

Okay, and in pneumatic system , is there any way to not let the used co2 get wasted and rather restore it in the main tank?
and if i use normal air rather than co2, what diff will arise?

and a single acting cylinder will work for more duration than a double acting one, right?
and is that cheaper?

Short answer is No, once used its exhausted.

Your second question re air instead of Co2, well you could use HPA, but you will not have the same volume of gas as you would with Co2, this is so because at around 60bar Co2 becomes liquid. Air on the other hand does not, and rules specify that pressure should not exceed 68bar.

A single acting ram will obviously consume less gas, don't know if there's any difference in price between single or double acting types, but most you'll find will be double acting.

thanks, thats helpful

so can u show me close up pics of your but with visible pneumatic flipper?

It will be difficult to understand what's in the system and how it works from a photo, a schematic is better... There are other ways to set up a low pressure system which may be simpler. This is how mine is set up...

thanks aton

Anything, else you would like to tell me, before starting pneumatics?
how many times does the actuator work if the tank is full(approx)?

**Rahulvyas** · 29th October 2013, 15:14

And the pic(diagram) you attached is for single acting cylinder?

Yes single acting with a bungee return, but can also be easily adapted for double acting. How many times you'll be able to fire the flipper depends on the size of the main tank you select, never counted on mine, but our 12oz bottle gave us more than enough for a single fight.

Good luck with your build and stay safe!
