Air pump Hailea BRZĘCZYK ACO-2204 for aquariums 120–300 L, model 11595

Hailea BRZĘCZYK ACO-2204 for aquariums 120–300 L is an external air pump designed to provide steady aeration for medium to large freshwater and marine tanks. The unit supports continuous oxygen supply and helps maintain circulation and filtration performance. Compatible with air stones, sponge filters and a variety of external devices, this air pump is intended to improve gas exchange and contribute to stable water parameters for fish, invertebrates and planted aquaria.

Advantages

The air pump delivers consistent airflow appropriate for aquariums in the 120–300 litre range while operating with energy efficiency typical for compact aquarium compressors. Its durable construction reduces the need for frequent replacement, and compatibility with common aquarium accessories ensures flexible installation options. The design minimizes vibration and noise during normal operation, supporting uninterrupted aeration and filtration systems.

Suitable for

• Freshwater and marine aquariums between 120 and 300 litres
• Sponge filters and undergravel or external filtration systems
• Air-driven decorations and multiple air stones or outlets

Key specifications

• Recommended tank volume: 120–300 L
• Continuous aeration output suitable for multiple outlets
• Compatible with air stones, air tubing and sponge filters
• Designed for continuous operation to support filtration and circulation
• Compact footprint for convenient placement near aquaria

How to use

Place the air pump on a stable, dry surface above or beside the aquarium to reduce the need for check valves; if installed below water level, use a non-return valve to prevent backflow. Connect appropriate air tubing to the pump outlet and route to air stones, sponge filters or other devices, trimming tubing length to avoid kinks. Start the pump and adjust the number or size of air stones and outlets until the desired bubble flow and filtration performance are achieved. Follow regular maintenance intervals to inspect tubing, connectors and any valves for wear or blockage.

Usage recommendations

For reliable long-term performance, place the pump on vibration-dampening material and ensure adequate ventilation around the unit. When powering the pump, use a surge-protected outlet and periodically check for reduced airflow that can indicate clogged tubing, worn diaphragms or the need for replacement parts. Match outlet distribution to tank needs by balancing the number of air stones and the depth of placement to optimize oxygenation without excessive surface turbulence.
