Fluval A101, A202 and A402 air pumps provide air for air stones, decorative devices and air-driven filters. The models cover different output ranges and should be selected according to aquarium size, required air volume and the number of connected devices.
Water depth, tubing length, distributors and air stones create resistance and affect the air volume delivered. When several outlets are used, the available output is divided between the connected devices. The complete air system is therefore more important than aquarium volume alone.
Install the pump in a dry, low-vibration position. If it is positioned below the water level, use a suitable non-return valve as required by the installation instructions. Inspect and clean tubing and air stones regularly.
