Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth. Compact environmentally dry sealed diaphragm system completely eliminating the maintenance issues associated with silicone, oil or grease filling. Break through, innovative over-molded first-stage endcap & environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage. Easy to grip DIN hand-wheel or over-molded yoke hand-wheel, only requires one hand to release. DIN, Yoke and M26 Thread available, 300bar, 232bar and M26 300bar (O2) respectively. 5 x 3/8” UNF (Unified National Fine) medium pressure ports. 2 x 7/16” UNF high pressure ports. The 5th 3/8” UNF medium pressure port includes a protective bumper when not in use. Forged first stage body with heat exchanging ribs for maximum thermal performance. Angled HP ports for optimal hose routing and fitting of transmitters. Forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation. Ribbed diaphragm clamp for improved heat exchange in cold water conditions. Double swivel hose for greater freedom of movement and comfort. Tested for Octopus use - EN250A to 60 meters cold water. Nitrox/Oxygen compatible – Up to 40% O2 outside the EU (European Union), within the EU anything above 21% O2 must use an M26 Connection. Simple to use with no dive adjustment controls and reduced chance of free flow occurrence, pre-settable cracking effort or venturi control by an Apeks approved qualified technician. High performance pneumatically balanced lever operated poppet valve. Large, diver friendly self-flushing controllable purge button. Front cover with over-molded elastomer incorporates a formed chrome plated brass plate improving durability of the second stage. Large protective elastomer bumpers on the side and on the top to protect the second stage from impacts and scratches in the most vulnerable places. Reversible second stage for either a left or right hand gas supply configuration. A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. Removable bungee necklace with lock out feature for retaining second stage in the mouth of an unconscious diver during rescue and to assist with jaw fatigue. Comfo-bite mouthpiece. Flexible nylon braided hose has better cold water performance than traditional rubber hose. Simple service kits. Easy to service. Color coded octopus hose.

Free Parts for Life Program (Regulator Service Agreement)

The Free Parts for Life Program allows the customer to receive free parts when the regulator is due for overhaul. Free parts consist of the normal replacement items as found in the Regulator 1st & 2nd Stage Service Kits. Labor charges are not covered. Assuming the program guidelines are followed, the Free Parts for Life Program will apply to the life of the regulator and will significantly reduce the cost of ownership. This program is in addition to the standard product warranties outlined in the owner’s manual. The Free Parts for Life Program is a commitment by you (the Regulator owner), your Aqua Lung Dealer and Aqua Lung. To participate, you must be the original owner and have purchased the regulator from an Authorized Aqua Lung or Apeks America Dealer. The regulator must be brought to an Authorized Dealer at least once a year for inspection or overhaul according to the below schedule:

Year #1: Inspection

Year #2: Overhaul

Year #3: Inspection

Year #4: Overhaul

Etc.

To keep the Free Parts for Life Program active, both inspections and overhauls need to be documented in the Annual Service & Inspection Record included in the Owner’s Manual CD or the Record can be found online. If an inspection or overhaul is missed, the regulator no longer qualifies for the Free Parts for Life program. Visit Water World SCUBA, your local Aqua Lung Dealer, for more information.
