Cressi MC5 Ellipse Regulator

Cressi MC5 Ellipse Regulator


Cressi MC5 Ellipse Regulator set is made up of the excellent 2nd stage Ellipse, with elastomer cover (Black version) combined with the MC5 diaphragm first stage.

The MC5 first stage is a diaphragm first stage of extremely low weight and size with highly technological content.

The sliding cylinder of the piston is sheathed with a special self-lubricating polymer which reduces internal friction to a minimum and totally eliminates any possible oxidisation that could alter the performance of the regulator over time.

The high performance is further increased by a special assistance chamber that triggers a strong Venturi effect between the central diffuser and the intermediate pressure outlets.
