Air Multiplier technology
Air is accelerated through an annular aperture, creating a high-velocity jet of air. This passes over an airfoil-shaped ramp, channelling its direction and creating areas of low pressure behind and around the fan. The change in pressure forces surrounding air to be drawn into the airflow, resulting in a powerful stream of smooth air.

The only fan heater with Jet focus control
Choose focused mode for long-range powerful airflow, or select diffused mode for wide projection to mix the surrounding air.

Long-range powerful airflow
Choose focused mode for long-range powerful airflow, or select diffused mode for wide projection to mix the surrounding air. In focused mode, warm air is accelerated through a 2.5mm aperture and over an airfoil shaped ramp. In focused mode, it is redirected by a focus ramp, which projects a powerful stream of warm air towards the user.

Wide projection to mix the surrounding air
Choose focused mode for long-range powerful airflow, or select diffused mode for wide projection to mix the surrounding air. In diffused mode, a jet of air is released from a second aperture. As the two jets meet, entrainment guides the airflow over a 45 degree angle, releasing a wide stream of powerful airflow.

Effective all year round
Using Air Multiplier™ technology to amplify surrounding air, AM09 projects heat further than conventional fan heaters. It heats the whole room – quickly and evenly. In cooling mode, the Dyson Hot+Cool™ fan heater keeps you cool with powerful airflow. With Air Multiplier™ technology, AM09 draws in up to 28 litres of air per second. It’s effective all year round, so you’ll never need to put it away.

Precise, energy efficient heating
In heating mode, the intelligent thermostat monitors the room to reach and maintain the target temperature – no wasted energy.

Sound 75% quieter
By reducing turbulence within Dyson Hot + Cool™ fan heaters, Dyson engineers were able to make them quieter. To do this, they streamlined the airflow paths within the machines, allowing air to pass through smoothly. They also designed a Helmholtz cavity for each fan, which captures and dissipates sound from the motor.

Perfect for night time use
Using an intelligent thermostat, the Dyson Hot+Cool™ fan heater maintains your target temperature while you sleep. Or you can set it to turn off using the built-in sleep timer. It has automatic cut-out and it’s the only fan heater with Quiet Mark accreditation – so it won’t keep you awake.
