Aqua One Stellar 380D Air Pump | Twin Outlet 2x190 L/HR Oxygen Pump Australia

Aqua One Stellar 380D Twin Outlet Air Pump. 2x190 L/HR Oxygenation for Hydroponics, Aquaponics and Aquariums

The Aqua One Stellar 380D is a high-performance twin outlet air pump designed for continuous oxygenation in aquariums, hydroponic reservoirs, and aquaponic environments. Delivering 2x190 L/HR across two independent outlets, it maintains optimal dissolved oxygen levels in water-based systems with quiet, energy-efficient operation.

Built with a long-life silicone rubber diaphragm, integrated air filtration, and backflow protection via two included check valves, the Stellar 380D is engineered for reliable long-term use in both hobby and commercial setups.

Key Benefits

• Twin Outlet Oxygen Delivery (2x190 L/HR). 380 L/HR total output distributed across two independent outlets for balanced multi-tank or multi-site oxygenation.
• Quiet Energy-Efficient Operation. Low-vibration design with rubber feet for noise reduction. Suitable for indoor grow environments and home aquarium setups.
• Long-Life Silicone Rubber Diaphragm. More durable and flexible than standard rubber diaphragms, maintaining consistent airflow output over extended operational periods.
• Built-In Air Filtration System. Integrated filter protects internal components from particulate ingestion, reducing maintenance frequency and extending pump lifespan.
• 2 Check Valves Included. Prevents backflow into the pump if power is interrupted, protecting the diaphragm and internal components from water damage.
• Vibration-Absorbing Rubber Feet. Reduces surface noise and vibration transfer during continuous operation.
• 4mm Airline Compatible. Standard fitment for all major hydroponic and aquarium airline tubing and manifold systems.
• Compact Space-Saving Housing. External non-submersible design for shelf or bench mounting adjacent to reservoirs and tanks.

How It Works

The Stellar 380D optimises three critical oxygenation variables. Dissolved oxygen levels: 380 L/HR of total airflow increases oxygen saturation across connected reservoirs, supporting root respiration in hydroponic systems and gill function in aquaponic fish tanks. Root zone health: continuous aeration prevents anaerobic conditions and the root stress and disease risk associated with low-oxygen nutrient solutions. System balance: dual independent outlets allow airflow to be distributed across two separate reservoirs, chambers, or grow sites without a secondary pump.

The result is improved plant health, stronger root development, and stable dissolved oxygen levels across all connected systems.

Why Dual Outlet Design Matters

• Multi-Reservoir Oxygenation from One Unit. Two independent outlets allow simultaneous aeration of separate reservoirs or system zones without additional pumps.
• Balanced Airflow Distribution. Equal 190 L/HR per outlet ensures consistent oxygen delivery to both connected sites without pressure imbalance.
• Backflow Protection. Included check valves prevent water from siphoning back into the pump during power interruptions, a common cause of pump failure in hydroponic systems.
• Quiet Indoor Operation. Silicone diaphragm and rubber feet reduce operational noise, making the Stellar 380D suitable for home grow rooms and living spaces with adjacent aquariums.

What Sets It Apart

The Stellar 380D sits in the practical mid-range of hydroponic and aquarium air pumps, delivering enough output for two medium reservoirs or one large DWC system from a single compact unit. The silicone rubber diaphragm is a meaningful upgrade over standard rubber diaphragms, maintaining elasticity and airflow consistency over longer operational periods without the cracking and stiffening that reduces output in cheaper alternatives. The included check valves are a practical inclusion that many pumps at this price point omit, and they provide genuine protection against the most common cause of pump failure in hydroponic systems. For growers running dual-reservoir DWC or aquaponic setups, the Stellar 380D eliminates the need for two separate pumps while maintaining balanced airflow to both systems.

Frequently Asked Questions

What size fittings do I need for Aqua One Stellar 380D Air Pump?

Hydroponic irrigation fittings are sized by internal diameter — common sizes are 4mm, 13mm (½"), 19mm (¾"), and 25mm (1"). Match fittings to your existing tubing or pump outlet diameter. When in doubt, 13mm is the most common size for standard hydroponic systems and is compatible with most pumps and mainline tubing in the 300–2000 L/hr flow rate range.

How do I prevent leaks with Aqua One Stellar 380D Air Pump?

Push-fit barbed fittings should be inserted firmly until they bottom out against the shoulder. Soft poly tubing grips barbs securely without clamps for most low-pressure applications. For higher-pressure or constant-run systems, add hose clamps over the barb connection for a leak-free seal. Always pressure-test your system for 30 minutes before introducing plants.

Does Aqua One Stellar 380D Air Pump ship fast within Australia?

Yes — Aqua One Stellar 380D Air Pump ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
