ATMOS First Stage
Environmentally sealed balanced diaphragm, an ideal first stage for use in extreme diving conditions, such as ice diving or diving in high sediment situations. An integrated LP swivel is utilized for ultimate comfort and hose routing. 5 LP ports, 2 HP ports for maximum hose placement.

ATMOS Pro Second Stage
Pneumatically balanced, user-adjustable second stage. This pneumatically balanced, adjustable second stage is sure to provide you the highest performance for many years. The pneumatically balanced second stage provides the lowest possible inhalation effort. The second stage adjustment allows you to adjust your breathing effort, fine-tuning the regulator to your desired setting throughout your dive. The venturi assist deflector vane directs airflow from the valve directly to the mouthpiece producing a smooth "venturi assisted" inhalation. Turning the venturi assist down, to a pre-dive position, prevents regulator free-flow while on the surface.

Pneumatically Balanced Valve Design
A common objection to typical adjustable second stages is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. Taking another stride beyond common second stage engineering, the Pro features a pneumatically balanced valve that maintains a preferred breathing resistance throughout the dive. Set it once and the ATMOS Pro automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no additional manual adjustment.

Diver Adjustable Inhalation Effort
Most downstream demand valve regulators are calibrated during manufacturing to a single, 'middle of the road' operation. Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the ATMOS Pro's adjustment knob enables complete control...set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.

Adjustable Venturi Switch
The adjustable deflector vane found in the ATMOS Pro diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. With the addition of a user-adjustable venturi system, full adjustment control rests in the hands of the diver.

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

Lightweight
The Pro's housing is made from an ABS/Polycarbonate composite blend of materials making the ATMOS Pro 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.

Nitrox Compatibility
The AT 400 Pro Regulator 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.
