The RS-790 delivers performance, durability and comfort making it the ideal choice for discerning divers.
 
First stage (R-700)
>     Balanced diaphragm first stage with anti-freeze system
>     Dry ambient pressure chamber ideal for temperatures below 50°F/10°C
>     Ribbed section to increase heat transfer and resist freezing
>     Two H.P. ports and Four L.P. (2 standard/2 high flow) ports
>     High flow L.P. ports offer up to 15% increase in air flow
>     DIN version available as RS-790 DIN (300bar/4350psi)
 
Second stage (S-90)
>     Lightweight, compact composite case design
>     Pneumatically balanced system
>     Venturi adjustment lever
>     Ortho-consciously designed mouthpiece
 
ADVANCED FLOW SYSTEM
The Advanced Flow System allows ease of air flow and makes air delivery smoother due to the curved housing structure.
    
COLD WATER READY
The Cold Water Ready feature enables the diver to use the regulator in water temperatures below 50° F / 10° C.
    
ENVIRONMENTALLY SEALED 1ST STAGE
The use of a secondary diaphragm and piston sealing the 1st stage preventing contamination or freezing when the regulator is submersed in contaminated or freezing water.
    
PNEUMATICALLY BALANCED 2ND STAGE
A balance chamber added to the regulator 2nd stage, providing equal pressure to both sides of the LP seat greatly reducing inhalation effort.
