Computer optimized design

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 A1's unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. 

Lightweight

The A1's housing is made from an ABS/Polycarbonate composite blend of materials making the A1 both extremely rugged and lightweight (5.4 ounces) and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives. The extremely ligweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized, utilizing a unique process to prevent corrosion. 

Patented orthodontic mouthpiece

To further reduce jaw fatigue, the A1 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw. 

Nitrox Compatibility 

The A1 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.
