This unit comes with R38 Insulated doors, as opposed to R-22 for the HV1000 standard. Homeowners can now quietly and efficiently reduce the indoor air temperature of their home, while improving air quality with the Tamarack Technologies HV1000 series of Whole House Fans. When the outside temp. drops below the indoor temperature, the HV1000 will draw cooler outside air, into the home. The hot air is drawn thorough the fan and up and out of the attic through exsisting attic and roof vents. Each unit is rated to handle approximately 2000 sq ft. At 2000 sq. ft - one complete air exchange occurs every 16 minutes. For homes larger than 2000 sq. ft we recommend the HV1600 2 speed unit.
