Dyson AM05 Hot + Cool Fan Heater, White/Silver (Certified Refurbished) Air is drawn in at the base of the machine It is accelerated through a 2.5mm aperture, which creates an annular jet of air that passes over an airfoil-shaped ramp, channeling its direction Surrounding air is drawn into the airflow, amplifying it, this is called inducement and entrainment Unlike with conventional fan heaters or fans, there are no chopping blades, so theres no buffeting, airflow is smooth Heat distribution: Many conventional fan heaters cant heat a whole room quickly because they use spinning blades powered by inefficient motors to distribute the air AM05 has Air Multiplier technology that amplifies surrounding air for long-range heat projection. It is fastest to heat the whole room Cooling: Some fan heaters claim to be cool air fans as well, but many have low airflow and low air velocity so theyre not effective With Air Multiplier technology, AM05 draws in up to 6 gallons of air per second, generating high airflow and air velocity to cool you effectively There are no blades  just an uninterrupted stream of smooth air Safe: Conventional fan heaters use fast-spinning blades and hot elements that have to be guarded by safety grilles AM05 has no blades or visible heating elements It cuts out automatically if tipped over Precise control: The Dyson Hot+Cool fan heater lets you select the target room temperature to the degree The brushless DC motor allows you to precisely control the airflow power No Burning smell: When dust collects inside conventional heaters it can emit a worrying burning smell The heating elements of AM05 never exceed 392F, which is below dust burning point, so there is no worrying burning smell Energy efficient: Many conventional fan heaters waste energy, some don't monitor the temperature of a room so they keep heating it beyond your requirements, and they don't heat the room evenly AM05 is efficient because it heats the room quickly and evenly, using an intelligent thermostat to control the temperature  switching heat on and off automatically Remote control: AM05 comes with a remote control It can be used to turn the machine on and off and to adjust oscillation, temperature and airflow power Its curved and magnetized to store neatly on top of the machine Touch-tilt: AM05 pivots on its own center of gravity, staying put without clamping It tilts 10 from upright in both directions, so you can direct airflow where you want it
