TUNZE® Aquawind eco chic

The TUNZE® Aquawind eco chic 7028.500 is a very low-noise aquarium ventilator provided with 12 V safety low voltage and it is easy to install on the edge of aquariums with a glass thickness of 0 up to 22 mm (0” - 0.866”). The angle of the Aquawind can be individually varied by tilt adjustment. The Aquawind creates an even air movement above the water surface and thereby accelerates the evaporation process. For standard aquariums of up to 800 liters (211 USgal.) (across an aquarium length of 2 m / 78.7”), this cooling can reach 2 to 4°Celsius (3.6° to 7.2° F). Due to its special design, a targeted flow is achieved over long distances. One ventilator is enough to efficiently cool even large aquariums.
