This fan heater, with a wide operating range, quickly warms up the ambient temperature. It can be adjusted from 1 to 37 degrees Celsius. As soon as the desired temperature is reached, the appliance switches off and it automatically restarts if a temperature drop is detected. By using the patented Air MultiplierTM technology, the air is drawn in via a mixed flow impeller; it is then accelerated through a 2.5 mm wide aperture set within the loop amplifier.
