The ORIGINAL direct-drive air compressor system (introduced on May 1st, 1999). Patriarch of the Air Line family of U.S. made hookah dive compressors mounted on Honda engines, and made solely for The Air Line by J Sink's customers by one of the largest compressor manufacturers in the world. You can be lured with copies of the innovator, but don't get fooled. It is unmatched in performance, features and low maintenance. Powered by the dependable 4.0 HP Honda engine, and featuring a heavy-duty, continuous-duty air compressor. Great for recreational diving.
