Aquarium Cooling Fan – Single Blade

The Aquarium Cooling Fan – Single Blade is an affordable evaporative cooling solution for aquariums that experience mild temperature increases in warm weather. The fan clips to the tank rim and directs a continuous airflow across the water surface, accelerating evaporation and carrying heat away from the tank.

Evaporative cooling can reduce tank temperature by 1–3°C depending on ambient humidity, making it effective in dry climates and air-conditioned rooms. In high-humidity environments the cooling effect is reduced. The single-blade motor is quiet and draws minimal electricity.

The fan is adjustable for angle to aim airflow precisely at the surface, and the compact clip design does not require modification to the tank. A cost-effective first line of defence for summer temperature spikes in tropical tanks or coolwater setups.
