TUSA Active Purge Assist (APA) – Advanced BCD Inflator System
Experience improved buoyancy control with the TUSA Active Purge Assist (APA), an innovative pneumatic inflator and deflation system engineered to deliver faster response, smoother operation, and greater convenience underwater.
Designed as an upgrade or replacement for conventional BCD inflators, the APA combines an assisted purge mechanism with an advanced Overpressure Exhaust Valve (OPEV), providing enhanced airflow for efficient inflation and deflation.
Compatible with most modern TUSA BCDs, the APA is an excellent choice for divers looking to upgrade their existing buoyancy compensator without replacing the entire BCD.
Product Features
- PNEUMATICALLY ASSISTED PURGE SYSTEM | Advanced technology improves air release response, allowing divers to make quick and controlled buoyancy adjustments.
- ENHANCED INFLATION & DEFLATION | Improved airflow performance compared to traditional inflator systems provides responsive operation underwater.
- ADVANCED OVERPRESSURE EXHAUST VALVE (OPEV) | Specially designed exhaust valve supports rapid air release and reliable buoyancy management.

BCD Compatibility
The TUSA Active Purge Assist is designed to fit most modern TUSA BCDs, making it a practical replacement or performance upgrade for many existing TUSA buoyancy compensators.
Compatibility depends on the specific BCD model and its inflator connection. Customers should confirm compatibility before purchasing.
Alternative underarm mounting configurations require the optional TUSA TC-753 Mounting Strap, sold separately.
For safe and reliable operation, installation and testing by a qualified scuba equipment technician are recommended.
