After more than 40 years of leadership in the SCUBA industry Bob Hollis has decided to step down as CEO of Oceanic, AERIS, LavaCore & Oceanpro but remain Chairman of the Board of AUP.
The A2 first stage is low-profile, durable, lightweight, and a great performer at a great price. It has one high pressure port and four low pressure ports to accommodate most hose arrangements. The A2 first stage is designed to be easy to maintain and service, and is known by divers and technicians worldwide. This first stage is manufactured from marine grade chrome plated brass and utilizes a non-balanced flow-by piston design and weighs 26 oz (737 g). An optional patented design also puts an end to flooded regulators without sacrificing performance! DVT (Dry Valve technology) is a revolutionary regulator technology designed to automatically prevent moisture and contaminants from entering your first stage, even if the dust cap is left off.
The AT600 is a High Performance First Stage with Environmental Seal. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The standard Diaphragm Regulator does allow water into the mainspring chamber so that the diaphragm can perform this transmission of pressure changes.
The first stage has 4 Low Pressure Ports (LP) and one High Pressure Ports (HP) and is Nitrox compatible to 40% out of the box.
