With two air outlets and adjustable airflow control, this silent aquarium air pump can operate multiple air stones, sponge filters, air-driven filters, or other aeration accessories simultaneously. Its compact design makes it an excellent choice for home aquariums, breeding tanks, quarantine systems, and other aquatic setups.

Ultra-Quiet Aquarium Aeration

The Hailea ACO-5504 uses an advanced damping system and multi-level muffler to minimize operating noise, making it suitable for bedrooms, living rooms, offices, and other areas where quiet aquarium equipment is important.

Powerful 4.5 L/Min Airflow

Despite its compact size and low 5W power consumption, the ACO-5504 produces up to 4.5 litres of air per minute, providing dependable oxygenation for aquarium air stones, sponge filters, and air-driven equipment.

Dual Air Outlets

The pump features two outlets, allowing you to connect two air devices simultaneously. This makes it convenient for running multiple air stones, sponge filters, or separate aquarium sections from one pump.

Adjustable Airflow

The built-in electronic airflow control allows you to adjust the air output according to your aquarium’s requirements, helping create gentle aeration for sensitive fish or stronger circulation when required.

Energy Efficient Operation

With only 5W of power consumption, the ACO-5504 is designed for economical long-term operation and is suitable for continuous aquarium aeration.

Advanced Diaphragm Technology

Special synthetic rubber components help maintain consistent airflow and pressure while the oil-free design eliminates the need for lubrication, reducing maintenance requirements.
