1.1. - T10 - T10 S.C.-T10 SC Cromo
The T10 balanced diaphragm first stage features a lightweight
structure of compact design, protected by the special and inno-
vative PVD (Physical Vapor Deposition) treatment, which creates
a highly resistant surface coating with extraordinary chemical-
physical characteristics and a high technical, very pleasing ap-
pearance. Unlike the T10 version, the Cromo version has a
protective surface coating of electroless chrome plating.
The ergonomics of the T10 balanced diaphragm first stage pres-
ents the functioning mechanism arranged perpendicular to the
air entry axis that thereby forms a “T” profile designed to guaran-
tee perfect arrangement of the HP and LP hoses, avoiding inter-
ference with the equipment connected to the first stage; reduced
size (particularly used in the SC version particularly suited to cold
water), as well as additional inspection capacity and access to the
HP valve mechanism to simplify maintenance and disassembling
of the regulator.
It provides outstanding respiratory performance, constant in any
use condition, thanks to the compensated diaphragm mecha-
nism that enables maximum respiratory comfort to be obtained
during any dive phase, from the surface to maximum depths.
In fact, the regulator provides the same intermediate pressure in-
dependent of the pressure contained in the tanks and maintains
performance at any depth.
Contrary to most regulators currently on the market, offering op-
timum performance when the tank is full at maximum working
pressure, the T10 first stage was designed to offer optimum per-
formance when the tank is close to empty.
This “hyper balancing” feature was possible using a system that
adapts intermediate pressure taking into account the air density
as the depth increases and the progressive increase in pressure
drop as the tank empties.
Thanks to this feature, the T10 first stage assists the diver in the
dive, guaranteeing the highest working performance which in-
creases further during the notoriously critical surfacing phase of
surfacing.
The compensated diaphragm mechanism phase, with a "T" air
entry, or rather the HP valve arranged perpendicular to the air
entry axis further guarantees considerable passage of air quantity
with a pressure drop, between the inhalation and exhalation
phase, which is reduced considerably.
These characteristics are the result of innovative technical solu-
tions in the design and make the 1st stage among the smallest
and lightest regulators on the market and one of the top perform-
ing in its category.
In this first stage (Fig. 1), the flexible diaphragm protects and seals
the mechanism inside the system and transmits pressure varia-
tions in the water to the high pressure valve.
