The most efficient whole house fan available today, the HV2800 Whole House Fan uses a revolutionary ductless design and drop-door damper to achieve a remarkable 93.3 CFM per watt efficiency. The HV2800 20-inch diameter, high-precision fan blades provide maximum airflow at high speeds, allowing you to quickly cool your home each evening.  Designed to mount on 16″ or 24″ on-center framing for easy installation,  factory-equipped with a 10′ power cord, the HV2800 is quick and easy to install in smaller homes and tight attic spaces. The fan is assembled in the USA with aircraft grade parts.

The HV2800 drop-down door and flange frame are powder coated white to blend in with most ceilings.  They can be painted on-site to match other ceiling colors.
