D420

Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology. • Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface. • Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve. • Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort. • Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier. • Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility. • Large purge button is easy to reach and depress, with or without gloves. • Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation. • Super-flow hose features an oversized bore that allows more air to flow on each inhalation. • Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest. • CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water below 39°F. • Weight (without mouthpiece): 7.6oz/216g. • Airflow at 2900psi/200bar: 1800 l/min - 64 SCFM.
