The AGIR Blackbird 30 / 36 wing, created for a single cylinder, is a single bladder buoyancy compensator. The outer shell is sewn from durable Cordura 1000. The inner bladder is made from Nylon 400 with high puncture resistance. Inflator with corrugated tube for increased capacity and strength terminated with a K-type head.
The overpressure relief valve (OPV) is located at the bottom of the wing. It is fitted with a nylon cable, allowing the valve to be opened with thick gloves and minimising the possibility of entanglement.
Its shape and 360-degree internal bladder allow the gas to move easily from one side of the internal bladder to the other. This ensures simple, fast and efficient release of excess gas.
The OPV can be used to adjust buoyancy in the horizontal position, reducing the need for the diver to move.
