Cooling fan aFAN is designed for cooling of water in the aquariums up to 30 gallons (100 liters) volume, and also for providing air circulation in any type of terrarium. aFAN fan creates a constant laminar air flow without messy rapid changes of speed and pressure. Air stream forms ripples on the surface and increases the area of contact between water and air, effectively cooling water. aFAN is powered by 5V safe voltage, from USB port or AC adapter 100-240V (included). aFAN is mounted on the outside of the aquarium that prevents its premature damage from moisture and corrosion. This is especially topical when aFAN is used in the marine aquariums. aFAN fan has three operating modes: Position "0" - OFF. Position "1" - normal rotation speed. Position "2" - high rotation speed
