HV1000 R38 Whole House Fan easily mounts in the attic on 16 or 24 inch on center joists. The attic fan can be mounted horizontally or vertically. This 1600 CFM* whole house attic fan quickly circulates air and cools your home whenever the outdoor air is cooler than the indoor air. The whole house fan operates at two speeds to push hot air, indoor air pollutants, allergens, moisture and odors out through attic vents or gables while pulling cool, fresh air into the home through the open windows. The air exchange naturally cools your home and can improve the indoor air quality. Like all Tamarack Technologies HV Series Whole House Fans, the HV1000 R38 features a unique self sealing door design. The unit includes R38 insulated doors that open automatically when the fan is operating and seal shut automatically when the fan is off, preventing cool air from escaping from your living area to the attic. The insulated doors also prevent heat loss through the attic during the cooler months. Installing an HV1000 R38 Whole House Fan reduces energy consumption and saves money because our fans use 10% of the energy of a central air conditioning system. Because the quiet cool whole house fan cools the home, it also reduces the amount of energy your air conditioner uses, reducing your energy bill. Based on the quality of this product and ease of installation, the HV1000 has been featured twice on the popular home improvement show “Ask This Old House”. ## Features - QUALITY AIRFLOW - Tamarack Technologies’ HV1000 Whole House Fan allows you to avoid using your AC when the outdoor air is cooler than the indoor air.
