50 SECOND STAGES
Using the included Allen key to unscrew the HP and LP caps of the-
first stage, you can open and disassemble the second stage, directly
getting to its inner mechanism. This unique and patentedfeature al-
lows to open the case in an extremely easy and quickway, toclean
it and check the perfect working of all its components.
In fact, the exhaust tee' s cap and central part are mechanically
tied with each other thanks to a new patented cam-lock system,
allowing to open and close the case very quickly, at the same
while blocking cap and diaphragm perfectly and precisely.
A regulator has never been opened and closed in such a simple-
and safe way!
The whole mechanism of second stage has been designed to
ensure easy and quick servicing and can therefore be taken out
of the case, without changing its calibration. Disassembling and
replacement of worn parts, on occasions of periodical servicing,
may be carried out holding the whole mechanism in one hand.

2.3 – Ellipse second stages
Ellipse second stage (in its different versions) is a revolutionary
downstream regulator, featuring elliptical shape, small weight
(only 158 g – the lightest in its class!), besides a futuristic design.
The regulator shows several innovative patented peculiarities and

comes in different versions, differing not only as to their first
stage, but as to the materials as well: for example, "Ellipse
Titanium" has inserts in titanium, a material with outstanding
mechanic, lightness, anti-corrosion resistance qualities; "Ellipse
Steel" has inserts in AISI 316, with unequalled quality as to anti-cor-
rosion resistance; "Black" features a front cap in soft elasto-mers.
All regulators have the same mechanism and functional peculiar-
ities, the same case in a new elastic techno-polymer with
excellent mechanic qualities which reduce noises dramatically:
therefore, from now on we will name the products generally
"Ellipse".
Ellipse was designed to supply air "on demand", that is only
when the diver inhales from the mouthpiece, causing a slight
vacuum inside the regulator, which must be very slight in order
not to make breathing difficult. Such vacuum acts on the special
variable-section elliptical diaphragm, which has been designed
to get a larger working surface and to keep the breathing effort
as low as possible, guaranteeing same performance as larger
sized regulators'.
The diaphragm, sucked in towards the inside, causes the central
plate to touch the lever, which has a new revolutionary shape,
designed to optimize and reduce dramatically the friction
