More of a tool then car question but I didn't know where else to put it.
So I have a decent compressor but 2nd hand less then decent air tools. I have a few big air guns that should get ANYTHING off. I have done my research on compressors and know that to efficiently run air tools it needs to be anything over 3CFM @ 90 PSI. The one I have is 5.5 so thats straight. The impact guns I have tried like I said are 2nd hand. I don't use them all that much. I do oil them every time I do use them but not when they are just sitting. One stays inside but one of the others is outside in an outdoor tool box. Does anyone know if they can actually go bad? They work but not anywhere NEAR how they're supposed to.
They should be ok as long as you keep them oiled. If they are really old they could just be worn out. For using air tools, the duty cycle of a compressor is just as important as volume and pressure because you should have one that is designed to constantly run 100% of duty time when you need it.
