You could (theoretically) use any inert gas as a propellant. However - the availability of alternatives to the usual CO2 or compressed air might be hard to come by - or prohibitively expensive.
While there are (more expensive) gases that can be used instead of CO2; they are still going to be compressed air. Whatever air you choose is going to be forced into a chamber and released on demand.
Most other alternatives would be explosive in nature. Even real bullets create compressed air: the explosion of the gun powder creates an air pressure wave that forces out the bullet. Caps and blanks can be made without bullet tips but they create an explosive force and will still discharge whatever is in front of them; but using blanks to shoot paintballs risks rupturing the paint balls in the barrel; and even if it doesn't the target is going to be hit with a projectile being fired at potentially lethal speeds.
Other alternatives are springs and rubber band mechanisms; but these are typically easier to design for single fire and not machine gun style.
If what you are trying to do is avoid buying the CO2; you would need to design a compressed air system with a pump style where you are creating the air pressure yourself.
paintballs should not be washed or dried.
No, they are not for sale anywhere to normal consumers.
if you paid for field fee then they should, if you are just looking to get it filled then no, the compressors required to fill your tank are VERY expensive and require regular maintenance
Tippmann first started out making half scale replica machine guns. In 1986 Tippmann began manufacturing semi and fully automatic paintball markers.
am looking for noritsu 2901 digital machine from Italy to buy.
A pneumatic machine is a device that uses compressed air to perform work. These machines are often used in industries for tasks like powering tools, controlling valves, or moving objects. The compressed air is typically generated by an air compressor and then used to actuate the machine's components.
On the model I have,the fps screw is located towards the back of the gun under the bolt
When it come to machine, it can be run on various energy source. Industrial machine usually run on electricity but some would run on compressed air and use electricity for fine control of compressed air. Some heavy industrial machine like driller might run on gasoline. Some pump might as well designed to run on steam pressure and compressed air. I believe there is no limit to what energy source it could be use to power, just what energy source would be convenience and fit to the task.
A rubber band is considered a type of simple machine known as a spring because it can store and release energy when compressed or stretched.
There is no fax machine with a camera,some people use there digital cameras instead of a fax machine.
I think about what it is like to be a human instead of a answer machine.
