Phynix asked:

Is there any way I can find an air compressor that can compress air to 110psi? And if so, how much Horse Power would it have? I’m sort of new to the world of compressors, but would like to find one that could do it. Also, how could I store something that had 110 psi?

I’m assuming this wouldn’t be easily done, would it?

Thanks.
