The thicknesses of the walls of the body have been optimized to minimize weight (380gr.). A semi-flexible elastomer sleeve protects the 1st stage of shock and erosion.
The HP seat is made of stainless steel AISI 316 and is replaceable in case of damage to maintenance.
The overcompensation of the mechanism ensures a slight increase in the intermediate pressure as the pressure drops from the bottle. The regulator therefore provides the highest level of performance in the final phase of the dive, without a doubt the most critical.

An advanced study of the internal air circulation and a special distribution chamber have allowed minimum pressure drop in forced breathing (0.5 bar), ensuring high performance use in any situation.
The optionally available MC9 isolation kit and anti-freeze SC (Seal Chamber) which completely isolates the diaphragm and spring from contact with water, making it ideal for operating in low temperature conditions and with very dirty water.
Especially effective filtering hat shaped inserted without circlip.
2 outputs HP and 4 LP.
Supplied as an INT (stapes) and DIN 300 bar. The screw DIN version has been made in stainless steel instead of brass to ensure greater resistance if dropped or bumped.
