The balanced diaphragm design makes it the perfect compact first stage for cold water and contaminated environments.
The pneumatically balanced diaphragm design provides consistent and smooth airflow regardless of depth, tank pressure, or breathing rate.
The dry chamber is completely isolated from the outside environment and features a diaphragm that prevents contaminated water from entering. The ribbing is designed to improve heat exchange, making the first stage waterproof to cold water.
Four LP ports and two opposing HP ports positioned at a 15° angle allow the first stage to be mounted high or low, also ensuring optimal hose/transmitter placement.
