About Cressi Ellipse Steel MC5 Regulator

The Ellipse uses an elliptical housing for the second-stage regulator which is made from hi-tech polymers. All the internal components of the Ellipse are a dependable high performance downstream valve design. Once the valve has open the air is channeled by injection to the liquid silicone mouthpiece creating a venturi-effect enhancing the performance. On the top of the housing there is a flow deviator that acts on the Venturi effect, with dive/pre-dive switch.

The Balanced 1st stage MC5 Hyper-balanced Diaphragm Actuated 1st stage has a lightweight body covered by a protective techno-polymer elastomer shell. The regulator is equipped with four low pressure and two high pressure ports. Internally the 1st stage is coated with an anti-friction anti-corrosion material that reduces resistance and allows the critical components to move freely. This makes the components perform and last longer between annual servicing and increases performance.

Research on internal air passages and incorporating a special assist chamber has lowered the drop of intermediate pressure upon inhalation and has kept this drop at a minimum, guaranteeing higher performance in any situation. Hyper-balancing allows for an increase of the intermediate pressure at maximum depths and when experiencing low pressure in the Scuba cylinder, offering higher performance at maximum depths and during the ascent phase of the dive.

    LeisurePro S  Yes, this reg can handle nitrox mixes to 40%.
    Shopper  What is the difference between the MC5 black and MC5 steel?
    LeisurePro S  The MC5 steel simply has a steel cap that cuts down on wear and tear.
    Shopper  Does this come standard with the yoke 1st stage? Also does it come with a BCD inflator hose?
    LeisurePro S  Yes, this will come in the Yoke formation but does not come with a BCD inflator hose. Those LP hoses are usually sold separately or along with the BCD.
