With its powerful ball-bearing supported ventilators, the Giesemann aquarium fan provides a strong surface flow over the aquarium, thereby cooling the water by means of evaporative cooling. The Giesemann fan is the only product on the market which is completely manufactured from premium-grade aluminium and is thus ideally suited for use in salt-water aquariums, whereas other ventilators typically after short periods of time start to corrode.
The fans are available in a three or five fan version, and are equipped with movable mounting feet and a rotatable holder for precise positioning. The ventilators move an air volume of 80,000 liters/hour or 130,000 liters/hour respectively and are very silent at the same time. The devices are powered with 12 V low voltage and fan speeds can be adjusted
