amtra Borea 80 80 LED is a adjustable cooling fan for aquarium with automatic temperature control system and LED for moonlight/actinic lighting. Equipped with an accurate probe for detecting the water temperature. The radial fan can be swivelled and adjusted to 5 different speeds to adapt it to multiple situations of tank sizes and desired temperature: once the temperature has been set, the fan will operate autonomously, switching on and off when temperature is reached. The water temperature can also be read at any time on the display. Operation and setting are extremely simple: the display screen constantly shows the temperature value detected by the probe. When the temperature detected by the probe is more or equal to the temperature to be kept set, the fan starts operating (at the settled speed). When the temperature detected by the probe is lower than the set temperature, the fan stops working.amtra Borea 80 LED -Aquarum fan cooler-+ cooling fan for aquarium with automatic temperat
