als offering outstanding mechanical properties and an extreme-
ly attractive and aggressive look.
CAD design and in-depth studies of water flows inside the front
of the regulator case have led to a further optimization and
enhancement of the already very high performance level of
CRESSI-SUB regulators, together with their user-friendly and
easy maintenance features.
Servicing in particular, has been made easier with the introduc-
tion of a side plug (20K) and related OR.
Warning: Servicing must be carried out by Cressi-sub
authorized centers only. Changing pre-set values can affect
the proper function of the regulator.
All internal components are in chrome-plated brass, stainless
steel, and acetal resin construction. Springs are manufactured in
harmonic stainless steel, diaphragms in silicon, O-rings and the
mouthpiece in allergy-free and comfortable silicon.
