The titan 1st stage regulator uses a balanced diaphragm mechanism that results in ease of breathing and consistent performance. It features a T-shaped compact and light design with 2 HP and 4 MP ports. The 2nd stage is a mid size, high performance demand valve that features a venturi knob which stops unwanted free flow when the regulator is out of a divers mouth. The demand valve is made from reinforced polycarbonate material that offers superior strength properties.
