4.0SPECIAL FEATURES OF THE MAXIMUS SRB3600 REGULATOR

4.1FIRST STAGE FEATURES

1The external adjustability of the first stage allows you to adjust the regulator output to match the type of diving being done. Relatively low outlet pressure (120 psi, 8.3 Bar) helps the regulator resist freezing in cold water diving. Medium outlet pressure (130 psi, 9 Bar), combines good breathing effort and durability. Relatively high outlet pressure (150 psi, 10 Bar), maximizes flow rate for high work effort dives.

4.1SECOND STAGE FEATURES

1The Maximus regulator's unique underarm hose routing protects the hose from snagging on obstructions during close quarters diving (coral, caves, wrecks, piers, etc.). This routing also allows for better head movement, thus lowering jaw fatigue caused by the hose pushing or pulling the second stage. A longer hose and unique swivels make the regulator ideal in air- sharing exercises.

2.The large high flow Wisdom® mouthpiece and the oval exhaust valve provide comfort and lower breathing resistance.

3.The externally adjustable demand valve in the second stage allows the diver to custom-tailor the regulator to the diving conditions and interstage pressure. The knob can be backed off for extended storage periods of longer than three months, eliminating the need for purge button lock down tabs.

4.To help prevent rapid pressure buildup in the first stage, the Maximus allows you to leave the knob in the backed off (counter-clockwise) position when the air is first turned on, and then close the knob (clockwise) until the airflow just stops. This is especially important when high (3500 psi, 241 Bar) tank pressures are used because it helps prevent rapid heat buildup at the piston seat.

5.The smooth hydrodynamic shape of the second stage is less resistant to forward motion through water, thus lowering jaw fatigue. The shape is also designed to resist free-flowing caused by rapid initial immersion or forward motion.

6.With lower interstage hose pressure (120 psi, 8.3 Bar), the heat transfer fins become warmer during exhalation, and transfer heat to the lever support area (thus aiding in freeze resistance). At high interstage hose pressures (135-150 psi, 9.3-10 Bar), the transfer fins become much colder, causing condensation and moisture retention for the diver.
