Air Multiplier™ technology.

Air is drawn in by the impeller, and passes over a 5° airfoil-shaped ramp – with the Bernoulli principle creating an area of low pressure. This induces air behind the fan, while surrounding air follows the airflow in a process known as entrainment – amplifying the initial airflow by as much as 15 times.

Jet Focus control.

In focused mode, warm air is powerfully accelerated from the rear aperture, where it’s channelled into a long-range jet of heat. Building on the principles of fluidics, first discovered in the 1960s, this powerful jet is deflected by a second jet, striking it at precisely the right angle. This guides the airflow over a wider angle, evenly heating a whole room.

Positive temperature coefficient ceramic plates.

Using a similar technology to cooling channels on jet engines, ceramic plates within the loop amplifier heat the airflow, whilst siphoning off a small amount of cool air. This cool air is circulated between the plates and the thermoplastic, creating a buffer to keep the surfaces of the fan heater cool to touch. The ceramic plates warm up to a self-regulating 392°F – below the burning point of dust.

Great fan heater

I cannot believe the power in this fan heater, I mainly bought it for the summer to use as a fan to cool me down but have used it during the winter on the hot setting and have found it to be excellent, it warms my room up in 10 mins.
