This pneumatically assisted purge system with OPEV (Over Pressure Exhaust Valve) offers significantly enhanced flow rates over a standard inflator system, which allows for immediate purge and inflation response. Additionally, the A.P.A is incredibly streamlined reducing drag and bulkiness. The system is designed for low-maintenance and easy care reducing inflator malfunctions and is optional on all TUSA BCJ's or as an add-on replacement accessory.
these were a replacment when i kept getting a small leak from the shoulder purge outlet from the original, took it too the local dive shop with the BCD which took it apart and rectified the problem for no cost saying the stripped it down checked it and now it was fine, but if the problem returnwd the would sent it back to Tusa although it was 4 yrs old but still imaculate, used it in the training pool and it still leaked,
So ordered an upgrade from DIVERS SUPPLY ( USA ) although i live in the UK, in the meantime one of my dive colleauges from the club took it apart used a small amount of silicone grease and fixed the original problem on the original inflate/deflate purge system.
Although the replacement fits perfect and looks great it is now kept as a spare because i only use the BCD for pool training and see no need for anything too fancy, my other BCD get's taken away on all other outings whether local diving or holidays abroad.
