We set out to make a "standard" regulator that was simple, dependable and economical. What we didn’t expect was that in tests it would outperform other high-end regulators. Not an easy feat for a "standard" downstream demand valve regulator. With the Alpha 9, you get effortless breathing in a compact design that is extremely tough yet easy to maintain and service. FEATURES - Designed to perform to the U.S. Navy's Class A standards at 198 feet
- Inexpensive to maintain
- Available with MaxFlex Hose which is a lightweight, flexible, Braided hose designed to outperform and outlive traditional rubber hoses.
- Demand Valve
- Integrated Purge Button
- Orthodontic Mouthpiece
- Nitrox Compatibility to 40%
- Weight (without hose) 6 ounces
- Dimensions (front profile) 2.9 inches
- Minimum Cracking Effort
- 1.1 CIW*
- Factory Set Inhalation Effort 1.2—1.4 CIW*
- 2 year warranty
- Limited Lifetime Service Agreement
- 30-Day Satisfaction Guarantee
TECHNOLOGY Best Price / Performance ratio in its class Not only is the Alpha 9 an economical buy for the diver on a budget, it is just as inexpensive to maintain. Standard replacement parts can cost as little as half of those in other regulators in its class.
Patented orthodontic mouthpiece To further reduce jaw fatigue, the Alpha 9 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.
Nitrox Compatibility The Alpha 9 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. SPECS | | Valve Type | DEMAND | Adjustment |

Did you know that it costs energy to breathe? The amount of energy your regulator requires to move each liter of air is called work of breathing (WOB). Lower work of breathing equals lower effort required to breathe and increased comfort and safety during a dive. How to Read Work of Breathing Charts The computer-generated breathing machine chart presented above represents a regulator's performance per standards established by the U.S. Navy's Experimental Diving Unit. Tests are conducted at 198 feet with approximately 3000-psi supply pressure, 25 breaths per minute of 2.5 liters each. (1) Inhalation - The chart shows one complete breath cycle, starting with inhalation on the left and continuing along the bottom to the right, staying mostly below 0.0; thus the inhalation work of breathing is reported in negative numbers. (2) Exhalation - The exhalation effort begins on the right and runs across the top to the left. These are all positive numbers since a diver (or the machine in this case) is blowing out (exhaling) rather than inhaling. (3) WOB - The total area inside the loop formed by the two lines is what the computer analyzes to calculate the regulator's total work of breathing - the amount of energy the regulator requires to move each liter of air. *Column Inches of Water |
