Whats in the box:1st Stage, 2nd Stage, LP Hose, Owners Manual
The ultimate performance to value ratio, the A2 Regulator is a great performer at a great price. Both the 1st and 2nd stages are low-profile, durable and lightweight. It has one high pressure port and four low pressure ports to accommodate most hose arrangements. The 1st and 2nd stage designs are easy to maintain and service, and are known by divers and technicians worldwide. The 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).
AERIS regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The A2's second stage unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation.
The A2's housing is made from an ABS/Polycarbonate composite blend of materials making the A2 both extremely rugged and lightweight, weighing 6 oz (170 g) and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives. The extremely lightweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized, utilizing a unique process to prevent corrosion. The A2 has a small profile with a front diameter of 2.9" (7.4 cm), and now comes with a MaxFlex Hose which is a lightweight, flexible, braided hose designed to outperform and outlive traditional rubber hoses. To further reduce jaw fatigue, the A2 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw. The A2 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. Like all Aeris regulators, the A2 comes with a 24 month limited warranty.
