BMCLs feature a 2-piece bag design for improved WOB performance and easy removal of the internal lung for cleaning or replacement. ADV Upstream Valve design is reliable and resistant to free flow which is a benefit for the addition of valuable diluent gas. Water Trapping T-pieces keep excess water from the breathing loop inside the counterlung for easy draining. Streamlined Hose Fittings keep LP hoses routed inside closest to the diver which avoids overhead interference. On the standard BMCL kit the OPV is placed away from diver on the right side. OPV also features a one way valve to avoid water intrusion when valve is pulled open to vent gas.

Machined DIL and O2 MAV controls ensure a rugged and reliable design, also allowing offboard gas plugin on both sides.
