Max makes it warm!
Its heating wires warm up air, which it blows in the room, to a nice temperature. Max heats in the transit time, when the big heaters are not turned on - Max warms feet in a cold office - Max makes cool rooms pleasantly warm.
Max has a lot of power! It can act as a normal fan or heat with 1000 or 2000 Watts power. The wished temperature can be set up steplessly. Max has also a antifreeze control and a overheating protection. Matti Walker was responsible for the design.
