you can use any AC compressor.. and may be able to use the air suspension compressor... the flowrate/compression rate all determines the duty cycle... anything will fill up a tank, to a certain pressure, but i'm sure any AC compressor will pump to high pressure... but it may not fill a tank up in decent time... you may use the entire tank right away filling a tire or running a tool.. and you are not going to want to wait for it to fill up again before you use it
