The Tamarack Technologies, Inc. HV1000 R38RF is a Whole House Fan that easily mounts in the attic on 16 or 24 inch on center joists.  The fan can be installed vertically or horizontally. This 1152 CFM* fan quickly circulates air and cools your home whenever the outdoor air is cooler than the indoor air. The HV1000 R38RF fan operates at one speed to exhaust 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. Easy operation with Radio Frequency Remote Control. The air exchange will naturally cool your home and can improve the indoor air quality.

Like all Tamarack Technologies HV Series Whole House Fans, the HV1000 R38RF 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. The insulated door design prevents cool air from escaping your living area to the attic. The insulated doors also prevent heat loss through the attic during the cooler months.

Installing an HV1000 R38RF Whole House Fan reduces energy consumption and saves money. Whole House Fans use 10% of the energy of a central air conditioning system. Because Whole House Fans cool the home, they also reduce the amount of energy your air conditioner uses, which will reduce your energy bill.
