The Atomic Stainless Steel Ai Power Inflator offers nearly the same level of corrosion-resistance, at a lower cost. The Stainless Steel Ai Power Inflator has the same 2-Year/300-Dive service interval as the company’s ST1 regulator. Ai Power Inflators can be attached to any BCD with included adapters. The Ai series is designed with large, over-molded buttons for convenient, smooth diver inflation. The inflators come with a 3/8″ threaded low pressure hose with quick-disconnect coupling.
