Purpose of attic exhaust fan.

The attic exhaust fan is a fan that is installed in an attic. Ideally this will lower the high temperatures that have built up in your attic. Many people confuse a whole house fan with an attic fan but the two accomplish different goals. The functions of the attic exhaust fan are written as follows.

Intake vents located at the lowest part of the roof under the eaves allow cool. It is designed to lower the temperature of an attic by exhausting air from the attic and replacing attic air with outdoor air. Ventilation fans ventilation fans or powered attic ventilators are designed to cool the attic pushing out the hot attic air and rushing in a flow of cool outside air. Designed to pull out hot air from a house or building.

A powered attic ventilator has a different purpose. The attic exhaust fan draws the fresh air through open windows and doors and removes hot humid stagnant and smoky air from the house. This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner. Unlike a ventilation fan a whole house fan an attic mounted fan that exhausts air from a home at night is designed to cool a house that is to lower the indoor temperature.

As the attic fan draws outdoor air into the attic it vents hot stale air out through attached dormers. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Hot air is vented outdoors reducing the temperature of the space without using the air conditioning system. This air is then exhausted through the fan to the outside.

It has a direct drive motor and the rating of the motor is 14 horse power. Cools your home at a fraction of the cost of air conditioning. A thermostat is used to automatically turn the fan off and on while sometimes a manual switch is used. Fresh air is pulled in from your soffits and or roof vent creating a draft through your attic.

The fan also pulls air into your attic simultaneously cooling your attic. An attic fan pulls air into the attic from the outdoors using the soffit vents you should already have installed in the eaves. A whole house fan serves the purpose of an exhaust system. A powered attic ventilator or attic fan is a ventilation fan which regulates the heat level of a building s attic by exhausting hot air.

An attic fan can be gable mounted or roof mounted. Attic fans exhaust hot air from your attic to the outside.
