Using Gunze Sangyo....

You should be ok. Gunze Sangyo also make Compresors for their air-brushes, very small and silent ones.

thanks sir!

i saw a compressor, a kawasaki brand and its small and cheaper.
but when i asked the store where i bought the gunze airbrush if i could use a compressor with the airbrush (Pro-II) she told me that i can't because it's only single action and she was offering me another airbrush which is very expensive. am not sure if she knows what she's talking about or just trying to sell me their brands.

i'd rather ask experts here in the forum.

thank you!

Sounds like she was trying to take for a ride there.

Single or double action don't really matter.
Granted the MK II is a very basic airbrush but where the air comes from(can or compressor) shouldn't make a difference as long as the pressure is ok

FWIW, a friend of mine is running 2 airbrushes of his Gunze compressor.

Kewl, thanks MadModelFactory!
