Fabio K Has DVT?
Jon S Yes, the Aeris AT 400 ION regulator has DVT
RALPH G Yes, it is listed as Aeris AT 400 ION DVT regulator.
SKU# AERAT4IRBL
CLAY H I assume you mean DVT (Dry Valve Technology), designed to keep moisture and contaminants out of the first stage, even if you forget to put the dust cap on.
Yes it does.
I also want to mention that the swivel 2nd stage means that you can't simply replace the hose with a standard regulator hose. It has to be replaced with a special swivel hose with a built-in (custom) 2nd stage swivel. I was not aware of this and DO NOT LIKE IT.
Why don't I like it? I assume it is: 1) more prone to failure than a standard 2nd stage hose and 2) costs more than a standard 2nd stage hose.
What they should have done was add a swivel fitting between a standard hose and a standard 2nd stage fitting.
FRANCES Z The regulator has DVT.
NATHANIEL P Yes, this uses the DVT feature.
James J Yes it has DVT, plus the protective rubber cap. My daughter loves this unit. The second stage is slightly smaller than most and the swivel head/hose helps with movent and lessoned strain on the jaw.
BRIAN M Yes has DVT but google for problems. Mine started freeflowing at 11 months and only 10 dives. Freeflows even in your mouth and with knobs in any configuration. Have to send mine back to aeris but they want to do 1 year service instead of warranty so extra $85 for that.
LISA R Yes it does love the regulator once one understands the position of the lever
