HV Whole House Fans

The HV1600 R38 Whole House Fan  easily mounts in the attic on 16 or 24 inch on center joists and is operated by a Radio Frequency Remote Control included with your purchase.  The fan can be installed vertically or horizontally. This 1527 CFM* fan quickly circulates air and cools your home whenever the outdoor air is cooler than the indoor air. The HV1600 R38 Whole House Fan  operates at two speeds 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. The air exchange naturally cools your home and can improve the indoor air quality.

Like all Tamarack HV Series Whole House Fans, the HV1600 R38 Whole House Fan 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 HV1600 R38 Whole House Fan reduces energy consumption and saves money. Tamarack’s Whole House Fans use 10% of the energy of a central air conditioning system thus cooling your home while reducing your energy bill.

As a result of the high quality of this product and ease of installation, the HV1600 has been featured twice on the popular home improvement show “Ask This Old House”.  A clip of the episode can be viewed here.
