Dyson Hot+Cool Fan jet focus (White/Silver)

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

Positive temperature coefficient ceramic plates - Using a similar technology to cooling channels on jet engines, ceramic plates within the loop amplifier heat the airflow, while 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 180° – below the burning point of dust.
