RESUN 12 Outlet Air Pump 3000 L/HR | Hydroponic DWC Aeration Pump Australia

RESUN 12 Outlet Air Pump 3000 L/HR. High Output Hydroponic Aeration for DWC and Multi-Site Systems

The RESUN 12 Outlet Air Pump delivers 3000 L/HR of continuous airflow for hydroponic aeration, reservoir oxygenation, and multi-bucket DWC systems. Built with electromagnetic linear diaphragm technology, it provides stable dissolved oxygen (DO) levels, low noise operation, and reliable long-term performance across large-scale grow environments.

The included 12-outlet manifold (4mm airline compatible) distributes air uniformly across multiple buckets, tanks, or grow sites, ensuring consistent root oxygenation and improved plant performance at every point in the system.

Key Benefits

• 3000 L/HR Maximum Air Output. High-volume aeration for large DWC systems, multi-bucket setups, and commercial reservoirs.
• 12 Outlet Manifold Included. Supports precise air distribution across multiple plant sites from a single pump.
• Electromagnetic Linear Diaphragm. Efficient, durable airflow generation with low energy consumption and long diaphragm lifespan.
• Low Noise Operation. Approximately 41 dB at 3m and 50 dB at 0.5m. Suitable for indoor grow environments.
• 30 kPa Maximum Pressure. Sufficient for multiple air stones and diffusers across large systems.
• Thermal Overload Cut-Out Protection. Automatic shutdown prevents pump damage under sustained load.
• IPX4 Rated Housing. Resistant to light moisture exposure in humid grow room environments.
• 4mm Airline Compatible. Standard fitment for all major hydroponic air line and manifold systems.

How It Works

The RESUN 12 Outlet Air Pump optimises three critical root zone variables. Dissolved oxygen levels: high airflow increases oxygen saturation in the nutrient solution, essential for root respiration and aerobic microbial activity. Root zone health: continuous aeration prevents anaerobic conditions and the root stress and disease risk that follows. Nutrient uptake efficiency: oxygen-rich environments improve nutrient absorption and metabolic activity, directly supporting faster vegetative growth and yield performance.

The result is faster growth rates, healthier root systems, and consistent crop performance across all aerated hydroponic setups.

Why High Oxygenation Drives Yield

• Low Dissolved Oxygen in Root Zone. High airflow at 3000 L/HR increases oxygen availability, directly improving root respiration and growth rate.
• Root Stress and Slow Growth. Continuous aeration promotes faster root development and more efficient nutrient uptake.
• Uneven Air Distribution. The 12-outlet manifold ensures consistent oxygen delivery across all plant sites without pressure drop.
• Pump Failure Under Load. Thermal overload protection and diaphragm design ensure reliable continuous operation across long grow cycles.

Performance Best Practices

• Operate with 12 to 15 kPa back pressure via air stones or diffusers for maximum diaphragm lifespan
• Install above water level to prevent backflow into the pump
• Use flow control valves to balance air distribution across all outlets
• Block unused outlets to maintain optimal pressure and efficiency

System Features

• 3000 L/HR (50 L/min) maximum air output
• 12-outlet manifold for multi-site distribution
• Electromagnetic linear diaphragm for efficient, low-maintenance operation
• Thermal overload cut-out for continuous run protection
• IPX4 moisture-resistant housing. Suitable for humid grow environments.
• 1.5m power cable for flexible installation positioning

Applications

• Deep Water Culture (DWC)
• Recirculating Deep Water Culture (RDWC)
• Multi-Bucket Hydroponic Systems
• Reservoir Aeration and Oxygenation
• Recirculating Hydroponic Systems
• Ebb and Flow (Flood and Drain)
• Greenhouse and Commercial Hydroponic Operations

What Sets It Apart

Most entry-level air pumps are single or dual outlet and lack the pressure output required for multi-site systems. The RESUN 12 Outlet Air Pump delivers 3000 L/HR across 12 independently controlled outlets, making it one of the most capable aeration solutions available for serious hydroponic growers. The electromagnetic linear diaphragm design operates at significantly lower noise levels than piston-based alternatives, and the thermal cut-out protection ensures the pump can run continuously without risk of overheating. For growers running 6 to 12 bucket DWC systems or large reservoir setups, this pump eliminates the need for multiple smaller units and the pressure inconsistency that comes with them.
