Description
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 anti-friction and anti-corrosion material 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 aspecial 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.
MC9 diaphragm 1st stage – Technical Features
- Working pressure (INT connection): 0-232 bar
- Calibration pressure: 10 bar
- Calibration adjustment range: +/- 0.5 bar
- Air supply: 4500 l/min (*)
- High pressure seats (HP) 2
- Low pressure seats (LP) 4
- Weight with INT connection: 590 g
(*)values measured at LP seat outlet with second stage connected and 150 bar pressure in the cylinders.
-Compact shape reduces weight and in-water drag.
-Nearly all of the face acts as a purge button for easy access and fast clearing.
-Dive/pre-dive Venturi switch boosts air delivery at depth and minimizes freeflow at the surface.
-Streamlined exhaust tee directs bubbles to the side for a clear field of view.
-Made from lightweight techno-polymers, reducing jaw fatigue while diving and reducing overall weight for travel.
