About Aeris AT 400 Sport DVT Regulator, New Style

Aeris' 400 Sport DVT regulator's patented dry valve design means you won't have to sacrifice performance and durability in order to have a regulator that won't flood This second stage will be the work horse of your dive gear; it will keep you breathing easily dive after dive High performance balanced diaphragm first stage with environmental seal and the added protection of DVT (Dry Valve Technology)

The Aeris 400 Sport DVT uses a high performance over-balanced diaphragm first stage with environmental seal and the added protection of DVT (Dry Valve Technology) DVT (Dry Valve Technology) is one of the most significant innovations in regulator technology in recent history DVT is a fully automatic valve that protects your first stage regulator's internal components against the harsh water environment in which we work and play; with no impact on the regulator's first-class performance

DVT provides an "automatic extra layer of protection" from environmental contamination such as dirt, dust, sand, spray, dripping and pooled water, or even a "flash flood" in a rinse tank DVT improves performance and reduces service costs associated with corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers The first stage has two HP and 4 LP ports, weighs 29 oz (822 g) The all chrome plated marine brass first stage regulator is an over balanced diaphragm design which is environmentally sealed 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 400 Sport DVT's lightweight design and patented orthodontic mouthpiece mean you'll be comfortable and breathing easily throughout your dive and won't face post-dive jaw discomfort once you've returned to the surface The 400 Sport second stage with an outer ring diameter of only 2 67" (6 8 cm) and 7 oz (198 g) weight The Sport's second stage is made from an ABS/Polycarbonate composite blend of materials making it both extremely rugged and lightweight, 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 400 Sport 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 Second stage comes with a venturi control switch 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 All Aeris regulators come with a 24 month limited warranty
Due to MFG restrictions, this can be sold to the USA and Caribbean only

    Comments about Aeris AT 400 Sport DVT Regulator, New Style:

    This is my primary regulator right now and so far I have been satisfied with its performance. After using it for the first time, it began to leak air out of the second stage and there was a strange vibrating sound everytime I would breathe. I sent it back into LeisurePro and they repaired and returned it to me in no time. I can't remember exactly what was wrong but I know they had to tear it apart and replace a seal. Since then it has performed flawlessly. The only complaint I have is that I sometimes find it slightly more difficult to breathe from in an inverted position as compared to other regs I have used.

      Comments about Aeris AT 400 Sport DVT Regulator, New Style:

      The Aeris Atmos Sport first stage coupled with the AT400 second stage with DVT and the Enviro Kit makes an excellent choice for anyone wanting effortless breathing without having to fumble with knobs and switches during a dive. I was really skeptical at first, but after diving the Aeris Sport, I'm sold..! You're basically getting the exact same Reg as if you purchased from one of the top line manufacturers, with the only difference being the shape of the purge, and the design of the logo..! Thanks Aeris and Thanks Leisure Pro..!
