Long range, powerful airflow Focused mode channels a powerful jet of air for long range, personal heating. Precise room heating An intelligent thermostat monitors the environment, projecting warm airflow to reach and maintain your chosen room temperature. 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. 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 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.
