The XS Compact AC2 Regulator is an incredibly reliable non-balanced flow-by-piston designed first stage regulator, perfect for new divers or as a stage bottle regulator system. Its fail-safe design ensures air delivery even in case of a first stage failure. The first stage features one high-pressure (HP) 7/16" threaded port, four low-pressure (LP) 3/8" threaded ports, and is made from marine-grade chromed brass for durability and longevity. A conical filter with greater surface area allows higher air flow through the first stage regulator.
The XS Compact Second-Stage housing is constructed from robust, non-corrosive hi-tech polymers and utilizes a reliable downstream demand valve mechanism. Air flow is channeled to the mouthpiece through injection, generating a venturi effect that enhances performance. The second stage is equipped with a flow deviator that influences the venturi effect, featuring a dive/pre-dive adjustment function. The large soft purge cover enables easy clearing of the second stage, and a comfortable silicone mouthpiece ensures a pleasant breathing experience.
Weighing 35 oz (994g) with hose, the XS Compact AC2 Regulator is a dependable and user-friendly option for divers. It comes with an owner's manual for your convenience.
