Apollo Bio Regulator A-320 NRX – Black Edition
The Apollo Bio Regulator A-320 NRX is a high-performance, environmentally sealed regulator system engineered for military, tactical and professional diving operations. Featuring a balanced diaphragm first stage with double diaphragm environmental sealing and an adjustable Bio-Air System (BAS) second stage, the A-320 NRX delivers exceptionally stable breathing performance across varying depths, tank pressures and environmental conditions.
The regulator’s environmentally sealed 1st stage isolates internal components from water, contaminants and silt intrusion — significantly reducing corrosion, freeze-up risk and performance degradation in cold or contaminated water environments. The second stage utilises Apollo’s proprietary Bio-Air System (BAS) with an internal bypass venturi design to deliver smooth, natural inhalation characteristics while maintaining efficiency under high workload.
Nitrox cleaned and compatible up to 40% oxygen as standard, the A-320 NRX is suitable for enriched air diving without additional preparation. Built with corrosion-resistant materials and precision engineering, this regulator system is designed to withstand demanding operational cycles typical of defence and commercial deployments.
