The
ABV-1 Ambient
Breathing Valve allows the user to breathe ambient air at the surface
conserving your tank air. It is simple to use and its low profile keeps
it out of the way.
To use the device,
while
on the surface simply
rotate the valve counterclockwise. The one way valve will open and
allow air into the FFM.
|
The
one way valve
located on the inside of the FFM ensures that your exhaled air does not
go back out the valve. Your exhaled air is sent out through the second
stage regulator ensuring you do not get a Co2 "build-up" in the FFM.
The valve also is
forced
closed when diving. The
over pressure in the FFM assures that. If you forget to close the valve
before diving, the valve disc will help keep water out.
|
When
the valve is
closed, it has a low profile. |
Even
when the valve
is fully open, the profile only slightly changes. When the valve is
open the diver breathes normally. He will notice little effort in
breathing while he conserves his tank air. |
