I made a mistake with my question. I don't want to change the oxy/nitrogen ratio of air, but I am wondering how compressable is air. If I compressed air at 70 degrees F into a bottle and obtained 100psi with the air temp at 40 degrees F, will I have doubled the oxy/nitro density of the air. What kind of compression ratios am I capable of? Thanks -----Original Message----- From: Thomas C.
