Blue Marine Cooling Fan 200 is an aquarium cooling system designed to lower water temperature by directing airflow across the water surface, promoting natural evaporation cooling. This helps maintain a stable temperature during warm conditions and heatwaves.

The unit is suitable for aquariums with a volume of approximately 100 to 200 litres. Cooling Fan 200 is equipped with four very quiet fans that distribute airflow evenly across the entire water surface, ensuring efficient and stable cooling without excessive noise. When correctly positioned, water temperature can be reduced by around 2–4 °C.

The fan unit features adjustable tilt angles of 0°, 30° and 60°, allowing precise airflow direction to suit different aquarium setups. The simple clip‑on mounting system fits aquarium glass up to 25 mm thick. With low power consumption, Cooling Fan 200 provides an energy‑efficient alternative to traditional aquarium chillers.
