Amron 8330i Air Control and Depth Monitoring System for 3-Divers

Model Number: 8330I

The Amron International Model 8330i Air Control and Depth Monitoring System for 3 Divers is a portable, self-contained three commercial diver high and low pressure air control and depth monitoring (pneumo) system for surface supplied commercial diving operations.

The Model 8330i is designed to provide a central control point for the supply of breathing air to three commercial divers and monitor their depth. The 8330i is housed in a durable, pressure-fused fiberglass case that provides a convenient, compact, rugged and professional system.

The system is specifically designed with three independent diver channels that meet the International Marine Contractors Association (IMCA) guidelines – IMCA D023 DESIGN for Surface Oriented Air Systems.
