Aquarium Cooling Fan – Dual Blade

The Aquarium Cooling Fan – Dual Blade increases cooling capacity over the single-blade model by running two fan heads from a single unit, covering more of the water surface simultaneously. This is particularly useful in tanks wider than 60cm where a single blade cannot move enough air across the full evaporative surface area.

The two fan heads are independently adjustable in angle, allowing the keeper to target the areas of the surface with the highest temperature. Combined airflow provides evaporative cooling of 2–4°C in appropriate conditions, meaningfully extending the safe temperature range of tropical tanks during warm months.

The dual-blade fan clips to the tank rim like the single model and draws only slightly more power. An ideal upgrade for 100–200L tanks and open-top aquascapes where surface evaporation is the primary thermal management tool.
