Aquarium air pump MARINA Multi Breeder AH-9369 – multi-outlet air supply for tanks

MARINA Multi Breeder AH-9369 is an aquarium air pump engineered to deliver adjustable, split airflow to multiple outlets. Designed for hobby and small-scale setups, this multi-outlet air supply enables connection of several airstones, sponge filters or external devices to a single compact unit, supporting improved oxygenation and gentle water movement across one or more tanks.

Advantages

The unit provides simultaneous air distribution to multiple outlets from a single compact housing, reducing the need for several pumps and simplifying installation. Its steady airflow supports aeration of biological filters and enhances surface agitation for gas exchange. The pump operates with relatively low noise levels appropriate for home aquariums and is compatible with standard airline tubing and common airstone sizes.

Suitable for

• Aerating several small aquariums from one pump
• Supplying air to multiple airstones or sponge/biological filters
• Supporting gentle water circulation and surface agitation in community tanks

Key specifications

• Multi-outlet air distribution for use with multiple airstones or filters
• Compact housing suitable for placement inside cabinets or near aquaria
• Compatible with standard flexible airline tubing
• Designed for hobby and small-scale aquarium systems

How to use

Place the pump on a stable, dry surface above the tank waterline or use non-return valves if the pump must be positioned below the water level. Connect airline tubing to the pump outlets and route the tubing to each airstone or filter inlet; secure connections to prevent air leaks. Adjust tubing length and outlet positioning to obtain the desired bubble pattern and water movement. Power the unit using the supplied cord and observe initial operation to verify even air distribution to all connected outlets.

Usage recommendations

For reliable operation, use quality airline tubing and check connections periodically for wear. Install check valves to protect the pump from backflow when tubing runs below the waterline. Clean or replace airstones and inspect tubing every few months to maintain steady airflow and prevent blockages.
