Hey, The fans are black box fans that you can purchase on Amazon and simply wire into the pressure switch on the rear side of the compressor. The fan wiring is included. Mine are wired on the motor side terminal to come on when the air compressor motor comes on and turn off when the motor stops. The drain bottles I purchased from a website that sells them for beverage dispensers i.e. beer etc :MicroMatic.com. Here's a link to the fans on Amazon: www.amazon.com/gp/product/B004YTSB7C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Also you'll need the fan grills: www.amazon.com/gp/product/B07VCNLQZD/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 I use thin black twisty ties to mount the grills on to the fans and to attached the fans to the compressors black bar handle. Are you an airbrush artist? Do you have/own a JUN-AIR compressor let me know...
