Page 4: Introduction
EN250 (European breathing regulator standard) breathing performance. In an emergency the AP100 is simplicity itself - just put it in your mouth and breathe! Unlike other make octoinflators you do not have to find and press any buttons. The Auto Air will draw air from wherever it can: either from your main cylinder if there is gas remaining (in octopus mode) or from the bladder of the BCD itself (in jacket-breathing mode). - Page 5 Ambient Pressure Diving Ltd.
