| All live support equipment is fully assembled by a factory trained
and
certified technician before you receive it. Unlike other
dive centers (even possibly your own local dive store) where you
may find anyone, even possibly an uncertified diver, assembling
your equipment. At www.UniversalDistributors.US
a scuba instructor assembles everything and all you need to do
is add air and water.
The job of the regulator is to supply air to the diver at
ambient pressure. The first stage of a regulator attaches to the
tank and reduces the pressure of the air in the tank to ambient
pressure plus a preset intermediate pressure. The air is then
sent down the hose to the second stage. Here the pressure is
reduced by that same intermediate pressure, leaving air at
ambient pressure.
Regulator first stages can be balanced or unbalanced.
Balanced first stages are designed to breath as easily at low
tank pressures and depths up to 90ft as when they are attached
to a full tank at the surface. Most regulators provide one or
two high pressure ports for pressure gauges and three or four
low pressure ports for second stages, LP inflator hoses or dry
suit hoses. Second stages offer external adjustments that can
be made by the diver while diving to vary the performance of the
regulator. The venturri assist is a two position adjustment that
creates a venturi effect to optimize breathing performance and
help prevent free flows at the surface. Another type of
adjustment is the adjustable air flow knob or dial. This
adjustment alters the flow rate to compensate for depth changes. |
