Ellipse Titanium/MC 9

2nd stage Ellipse Titanium

A latest generation regulator, loved by both professional and recreational divers thanks to its excellent performance. The small size, combined with the use of sophisticated techno-polymers and various titanium parts allow the weight to be kept to an exceptional minimum. Technologically the regulator is truly avant-garde, thanks to a series of unprecedented features, covered by a patent, that enhance its performance. 

Amongst which:

• The elliptical casing with special fold out opening.
• Instant cam-lock closure of the casing.
• The folding diaphragm for use with a large regulator lever.   
• The regulator lever with its computer designed profile.
• The tilting movement of the piston.
• The insulating anti-freeze between the regulator valve and casing.
• The possibility of removing the entire regulating system from the body of the 2nd stage, for quick and easy maintenance.

The result of so much technology is a regulator that supplies air smoothly and with unprecedented fluidity. All this with an excellent price/quality ratio.

1st stage MC9

Hyper-balanced Diaphragm 1st stage with highly technological content that places it at the top of the Cressi range. Very light body covered by a protective elastomer shell. Cylinder sheathed in an antifriction and anticorrosion materia l that guarantees perfect sliding of the piston and long maintenance intervals. The nozzle, made from 316 stainless steel, can be easily replaced , thus ensuring perfect air-tightness, even after many years of use. Advanced research on the passage of internal air and a special assistance chamber have enabled the drop of pressure upon inhalation to be kept to a minimum, thus guaranteeing high performance in any situation. Hyper-balancing allows for an increase of the intermediate pressure at maximum depths and lowering of the pressure in the tank , offering higher performance during the delicate ascent phase and at maximum depths. DIN 200/300 bar fitting in stainless steel which prevents deformation of the thread in the event that the regulator suffers any falls.
