The HV1000™ and HV1600-G™ are an original design in whole house cooling fans. Engineered to reduce indoor air temperature, the HV pushes the hot air out of the house through the attic and replaces it with cooler outside air. The HV utilizes twin, high-tech, super efficient fan motors to minimize noise and power consumption. Our systems have the industry's only automatic door assembly, providing an air-tight seal with an insulating value of R-22.
Radiant heat from the sun beats down on houses all day. On a hot, sunny day the temperature at the attic floor can reach as high as 140 degrees! The indoor temperature will often remain higher than the outdoor temperature for several hours. By pulling heat out of your home, cooler outside air can be drawn into the home. The heated air is then pushed out of your home through the attic vents.
Extremely economical, the HV uses about the same amount of electricity as two sixty watt light bulbs. If you have air conditioning, you can reduce the costs of A/C by as much as 30%. Motorized, gasketed and insulated doors close to form an air tight seal, preventing heat loss in colder weather.
Quick and easy to install, the fan housing will fit either 16" on center or 24" on center rafters with no rafter cutting! The low power system can be connected to any available power source. The grille attaches to the ceiling below for a clean, finished look from the living space.
The HV systems require no maintenance. With its automatic door assembly, there is no need to venture into the attic to shut down your ventilation system during cold weather. There are no belts to tighten or motors to lubricate.
A Note on Air Flow and fan sizing. How much air needs to move through your house to make it cooler? The following table shows estimates of how quickly all the air will move through different size houses with different size fans.
