The Cressi AC2 first stage is an unbalnaced flow-by piston design and is extremely light weight. It has an almost bullet-proof design that's fail-safe.
It has 4 low pressure (standard 3/8-inch thread) ports and 1 high pressure (standard 7/16-inch thread) port and is made from marine grade chromed brass for reliability and durability! A conical filter with a greater surface area is used for higher air flow through this first stage.
