AquaNatura aquarium air pump TN-45213 — 2 x 3.4 l/min, 5 W

The AquaNatura aquarium air pump TN-45213 delivers two independent air outlets with a rated flow of 2 x 3.4 l/min and a power consumption of 5 W. Designed for aeration, mild circulation and operation of air-driven ornaments or small filters, this compact pump supports stable oxygenation in small to medium aquariums. Quiet operation and dual outlets allow splitting air supply between two points or running two accessories simultaneously.

Advantages

The pump provides two separate outlets with consistent flow, allowing flexible distribution of air to different parts of the tank or to two devices. With 5 W power consumption it is energy-efficient for continuous use. Its modest flow rate of 3.4 l/min per outlet is suited to maintaining oxygen levels without creating strong currents, and the compact design simplifies mounting or placement near the aquarium.

Suitable for

• Aeration of small and medium freshwater aquariums
• Powering air-driven ornaments such as bubblers and stone diffusers
• Providing air to sponge filters or small airline-operated filters
• Supplementary circulation in low-flow setups

When it may not be suitable

This pump is not intended for large aquariums or systems requiring high-volume air delivery; its combined flow and single-speed operation limit use in high-demand setups. It may not be adequate where precise adjustable airflow or very low-noise laboratory-grade performance is required.

Key specifications

• Air outlets: 2 independent outlets
• Flow rate: 3.4 l/min per outlet (rated)
• Power consumption: 5 W
• Suitable for: small to medium aquariums
• Primary functions: aeration, powering air-driven ornaments and small filters

How to use

Place the pump on a stable, dry surface above the waterline when possible, or use a check valve to prevent backflow if the pump is positioned below aquarium level. Connect silicone tubing to the desired outlet(s) and route it to air stones, sponge filters or ornaments; secure tubing to avoid kinks. Allow the pump to run continuously for consistent oxygenation, and periodically inspect tubing and connections for wear or leaks. Follow manufacturer guidelines for safety and ventilation around the unit.

What to consider before purchase

• Confirm aquarium size and required aeration capacity to ensure 2 x 3.4 l/min is sufficient
• Decide whether two independent outlets meet your distribution needs
• Consider whether a model with adjustable airflow or higher flow rate is needed for larger setups
• Check available space and placement options near the aquarium, and plan for tubing and check valves if necessary

Usage recommendations

For best results, use the AquaNatura TN-45213 with appropriately sized air stones or sponge filters and include a non-return (check) valve if the pump will be placed below tank level. Regularly clean or replace air stones and inspect tubing to maintain steady airflow and prevent interruptions in oxygenation.
