Reliability of a refrigerator compressor? Need answers


I am building a modle of a 3 barrelled Vulcan minigun for an airsoft project. I need to know if a refridgerator compressor will put out enough psi to propell an airsoft bb effectively. If you have any answers or suggestions please reply

Pressure is not the problem. It certainly will produce enough pressure. I seriously doubt the flow rate will be sufficient though. A real 6-barrel Vulcan cannon fires approximately 6000 rounds per minute, or 100 per second. If you want any semblance of realism, you'll need to make your airsoft version fire at least 40-60 per second (800-1200 RPM for your 3-barrel assembly). That requires a LOT of air. CO2 or a high pressure air tank (like 3000PSI air for paintball) would probably be the only feasible option, aside from a fairly large 2-stage compressor.

The air supply is probably the easiest part of this project.

Thank you I just need to figure out how to build the air supply with a trigger or button? Any suggestions?

Btw way an airsoft bb is a platistic sphere shot out of a a gun similar to a paint ball gun, they are harmless, basically non-lethal bb guns

I think I follow what you are doing here, so: Would a tank of compressed nitrogen do the job?

Well is a tank of compressed nitrogen expensive? Because I'm trying to keep the price as low as I can. and how would I get my hands on compressed nitrogen
