About

If there is not enough fresh air inside a room, pollutants can sometimes accumulate to levels that can cause health and comfort problems. By using ventilation fans you can lower the concentrations of indoor air pollutants in your home by increasing the amount of outdoor air coming in.
Nearly all home cooling systems as well as forced air heating systems, do not mechanically bring fresh air into your house. Opening windows and doors, operating window or attic ventilation fans, when the weather permits, or running a window air conditioner with the ventilation control open increases the ventilation rate. Local bathroom or kitchen ventilation fans that exhaust outdoors remove contaminants and pollutants, including moisture, directly from the room where the ventilation fan is located and also increase the outdoor air ventilation rate.

Why ventilation fans

Ventilation fans are an excellent way to ventilate your entire home efficiently, and cheaply.
A ventilation fan is a motorized ventilation device that helps to draw out stale and impure air from your home and bring in fresh air and improve the quality of indoor air.

Types of ventilation fans

Ceiling mounted ventilation fans
Ceiling ventilation fans are those which are installed in the ceiling. These fans push out stale air from your home upwards through the roof.  The ventilation fan is connected to ducting, which is exhausted outside the house through an external vent, like a roof cap or soffit exhaust vent.

Wall mounted ventilation fans
These types of ventilation fans are installed directly on exterior walls. Because they are installed on exterior walls of the home and not on interior walls, the stale air has a direct route to the outside of your home and no ducting work is needed when installing these ventilation fans.

Exterior remote mounted ventilation fans
These types of exterior remote mounted ventilation fans are installed outside your house and drag out stale indoor air instead of pushing it out like others ventilation fans which are installed inside.
Exterior remote mounted ventilation fans are very noisy but the noise remains outside because they are installed outside your house.
