O2MOS builds DC-powered PSA oxygen generators that run off a truck's own battery or a vessel's DC supply — turning ordinary intake air into a steady, high-purity oxygen feed for live fish tanks, mile after mile.
Transporting live fish over long distances demands a stable, high-purity oxygen supply to hold water quality steady and keep fish stress to a minimum. Our PSA (Pressure Swing Adsorption) oxygen generator is engineered specifically for live fish transport trucks, delivering a cost-effective, portable, and efficient oxygen source for the entire trip — running on DC power, so there's no AC conversion to worry about.
We supply PSA oxygen generators sized for 1-ton and 5-ton live fish trucks, and the same platform runs onboard vessels when paired with a compatible DC power supply unit and integrated safety alarm system.
Ambient air is drawn in, filtered, and separated inside the vehicle — producing a clean, concentrated oxygen stream with nothing to refill and nothing to haul.
Outside air (~21% O₂) is drawn into the unit.
Nitrogen and contaminants are filtered out under pressure swing adsorption.
Clean oxygen (≥90%) is produced on demand — no tanks to refill.
Delivery is metered per tank, typically ≤3 LPM per line.
Oxygen is diffused into each live tank to hold DO steady.
Every installation is monitored end to end, so a fault in the generator never means a fault in the fish tank.
Delivers up to 90% oxygen concentration to hold water quality steady and reduce fish stress in transit.
Runs directly off the vehicle's battery with minimal impact on fuel consumption — no external AC power required.
Sized to fit both compact and heavy-duty live fish trucks, and adaptable to marine vessel installations.
Ambient air is filtered before separation, so only clean, contaminant-free oxygen reaches the tank.
No refillable oxygen tanks to buy, transport, or swap — the generator produces oxygen on demand.
Real-time monitoring with automatic alerts keeps the driver informed and the tank protected at all times.
Vibration-, moisture-, and corrosion-resistant construction, built to handle demanding transport conditions.
Modular, service-friendly layout allows quick inspection and part replacement with minimal downtime.
Proven over 15+ years of field use, with regionally supported service for fast follow-up.
