Air pump Tetra Pompa napowietrzająca APS 400 – dual outlet, black

The Tetra Pompa napowietrzająca APS 400 is a compact aquarium air pump with a dual outlet design in a black housing. It is intended to provide steady aeration and gentle water movement in small to medium-sized aquaria, supporting two separate air lines or accessories. The pump supplies continuous airflow suitable for air stones, decorative aeration features and small external or internal sponge filters, helping to maintain oxygen levels and improve circulation.

Advantages

The dual outlet configuration allows connection of two air-driven devices simultaneously without the need for an additional splitter. The black, compact housing reduces visual impact near the aquarium and fits unobtrusively in aquarium cabinets. The unit is designed for consistent, stable airflow to support oxygenation and surface agitation and operates with moderate noise levels suitable for domestic use.

Suitable for

• Aeration of small to medium aquaria
• Powering air stones and decorative aeration ornaments
• Supplying air to small sponge or undergravel filters
• Dual-device setups where two independent air lines are required

Key specifications

• Dual air outlet design for two simultaneous connections
• Compact black housing suitable for discreet placement
• Stable continuous airflow tailored for small-to-medium tanks
• Low to moderate operating noise for home aquaria

How to use

Place the pump on a stable, vibration-dampening surface near the aquarium, ideally lower than the waterline to avoid siphoning. Connect airline tubing to each outlet and route tubes to air stones, ornaments, or filters inside the aquarium. If the tube runs above the water level, install a non-return valve to prevent backflow. Power the pump from a suitable mains outlet following local electrical safety requirements and observe first-time operation to ensure both outlets deliver steady bubbles.

Usage recommendations

For reliable long-term performance, position the pump outside of direct humidity and avoid submerging the unit. Regularly check and replace airline tubing and air stones if airflow decreases; periodic inspection of connections will prevent leaks. If quieter operation is required, place the pump on a foam pad or anti-vibration mat and ensure it is not in direct contact with rigid surfaces.
