HIX Auto model N800 16" x 20"

I am interested in buying your advertised HIX N800 press/printer but it says it is not sold with the air compressor. Can you please tell me the #1 suggested air compressor to use that is also the quietest? Cost is not a factor here so I am most interested in figuring out what ball park I am looking at and which specific compressor would you suggest knowing that I want it to be the quietest possible. On the opposite side of the spectrum I would also like to know what would be a less expensive option for a quieter smaller compressor that is also compatible and on the upper end of quality, but would still work for large and mass quantity printing. Thank you for your time and assistance! Have a great day!
