The Tamarack Technologies, Inc, HV1600 R50 is a Whole House Fan that easily mounts in the attic on 16 or 24 inch on center joists. The unit can be mounted horizontally or vertically. This 1600 CFM* fan quickly circulates air and cools your home whenever the outdoor air is cooler than the indoor air. The HV1600 R50 operates at two speeds  to exhaust hot air, indoor air pollutants, allergens, moisture, and odors out through the 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 HV1600 R50 features a unique self sealing door design. The unit includes R50 insulated  doors that open automatically when the  fan is operating and seal shut automatically when the fan is off. The insulated door design prevents the cool air from escaping your living space to the attic. The insulated doors also prevent heat loss through the attic during cooler months.

Installing an HV1600 R50 Whole House Fan reduces energy consumption and saves money. Whole House Fans use 10% of the energy that a central air conditioning system uses.  Because the HV1600 cools your home, it reduces the amount of energy needed to run your air conditioning  which reduces your energy bill.

Based on the quality of this product and the 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.
