Generate high-purity oxygen directly from DC 12V or DC 24V vehicle power. Designed for live fish trucks, carrier vessels, shrimp logistics, and aquaculture transport.
Oxygen depletion and water-quality deterioration are key risks during live fish transport. O2MOS helps maintain stable oxygen supply in mobile environments.
Stable oxygen supply helps reduce mortality risk during transport.
Transport tanks require careful gas and water-quality control.
High stocking density increases metabolic waste and stress.
Higher temperature increases oxygen demand and risk.
Separated BED and compressor configuration supports compact installation in trucks, small boats, and mobile transport systems.
Available for 12V and 24V vehicle power systems.
Reusable PSA system reduces routine oxygen refill logistics.

PSA generator, power supply, battery, flow meter, air stones, and emergency oxygen backup can be configured as a complete mobile oxygen platform.

Pressure Swing Adsorption uses zeolite molecular sieves to extract oxygen straight from ambient air. No tanks, no deliveries — continuous supply powered by your vehicle's battery.
Ambient air is drawn through dual-stage filtration — HEPA and line filter — removing dust, oil, and moisture before processing.
Under pressure, zeolite beds selectively trap nitrogen molecules. Oxygen — being less adsorptive — passes through freely.
Concentrated O₂ at 90%+ purity is collected and fed into the fish transport tank via flow meter and air diffuser.
Dual zeolite towers alternate in adsorption and regeneration cycles — delivering uninterrupted oxygen output 24/7.
90%+ O₂ output under standard air conditions
24/7, 365 days — never interrupted
Durable high-quality Zeolite media
Split BED/COMP design for flexible install
Runs directly from vehicle battery 12V/24V
DC-powered models for 1-ton trucks, 5-ton trucks, small boats, and transport vessels.

The O2CALL emergency unit monitors oxygen pressure and DC power. It supports automatic backup oxygen supply and operator alarms when abnormal conditions are detected.
Backup oxygen valve can open when pressure drops below the setpoint.
Pressure and DC power abnormalities are indicated by alarm and LED.
Operator can manually boost oxygen supply when required.
One-touch fittings support quick installation and service.
Modular accessories allow flexible installation according to tank layout and vehicle type.

Status monitoring and alarm interface.

Independent oxygen flow adjustment.

Vehicle-based power connection.

Operator-friendly installation inside vehicle cabin.
Real installation photos improve buyer confidence and show that the system is already used in live fish transport environments.
Real-world metrics from deployments across Korea's live fish transport fleet since 2020.
Replace expensive liquid oxygen cylinder refills with on-demand generation from ambient air.
Consistent DO levels throughout transport — fewer losses and better product quality at delivery.
No high-pressure liquid oxygen storage on the vehicle — operates safely at all times.
Runs off existing DC 12V or 24V vehicle power. No generator, no separate power source needed.
Compact, reusable design with BLDC compressor and durable zeolite. Minimal downtime.
Cabin oxygen supply relieves driver fatigue and drowsiness during long-haul live fish transport.
