TUSA RS-790 Regulator

TUSA's RS-790 Regulator has an all chrome plated marine brass first stage regulator that is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. KEY FEATURES • 1st stage balanced diaphragm design • Anti freeze system • Nitrox compatible up to 40% • Pneumatically balanced 2nd stage design • Venturi adjustment lever reduces free flow
