The newest addition to the Ecofan® family, the UltrAir Model 810 produces higher airflow over a wider range of stove surface temperatures. The UltrAir delivers 15 to 90% more air at mid to low stove temperatures. Ecofan® circulates warm air throughout the room which increases the user’s comfort. These fans are designed to sit on top of a freestanding wood or pellet stove. Ecofan® generates its own electricity without cords or batteries. Ecofan® starts automatically when placed on top of a stove and adjusts its speed with the stove temperature. As the stove heats up, Ecofan® runs faster. As the stove burns down and cools, Ecofan® automatically shuts off. | High efficiency design | Creates its own electricity | Circulates warm air throughout room | Greater airflow & velocity at lower stove temperatures | New high efficiency blade design | Designed for use on new EPA stoves | No assembly required | Silent operation | 14% cost savings and reduced emissions from burning less fuel | Higher airflow at lower temperatures | Increases comfort more quickly | Effective on wood, pellet and gas stoves | Ready to use out of the box | No loud blower noise
