Room Ventilation Fans

Ventilation fans are a means of providing mechanical ventilation for rooms. Traditionally, large windows and doors have always been used to create the circulation of fresh air indoors. However, in modern times, it has become increasingly difficult to provide rooms with sufficient natural ventilation. This is very true in the case of cramped living spaces such as small apartments and rooms. Room ventilation fans are of utmost importance in such environments.

What are Room Ventilation Fans?

These fans also have blades like regular ones, but they are meant to serve the purpose of ventilation. The function of these fans is to suck out stale air from a room and expel it outdoors, bringing in fresh and cool air. Room ventilation fans are usually installed on an exterior wall or on the ceiling/roof that opens out to air. In rooms where such a provision is not possible, the ventilation fans are connected to ducts that allow the air to pass outside.

Types of Room Ventilation Fans

Depending on the need for ventilation, the right type of fan needs to be selected. Not all rooms require the same kind of fan, since the toxins present in the air might vary from room to room. The air in some rooms for instance might be high in moisture; while in others there might be more smoke. Keeping these factors in mind, different types of room ventilation fans have been designed.
  • Bathroom Fans: Ventilation fans for a bathroom may be installed on the wall or on the ceiling. Generally it is preferred to make the installation on an exterior wall. For large bathrooms, more than one ventilation fan is used. A shower fan is generally installed in separate shower areas to remove excessive moisture from the air. Bad odors and toxic chemicals in the air are also removed by bathroom ventilation fans.

  • Kitchen Fans: Fumes, smoke, grease and strong odors are released during cooking. If these are not cleared up in time, the environment could become hazardous. Again, wall or ceiling exhaust fans may be installed. Hood fans are also quite popular, and are installed just above a stove top. This way, fumes can be sucked up as soon as they are released, without spreading to the entire room.

  • Attic Fans: Storage spaces such as the attic tend to have a buildup of stale air. Moisture in the air could easily cause the formation of mildew. Same is the case with basements and garages. Ceiling fans are more common with attics, removing stale air directly outdoors through the roof.

  • Other Room Ventilation Fans: It is common to find small rooms these days in cramped up apartments that do not receive sufficient fresh air or sunlight. Small windows drastically reduce the circulation of air. In such rooms, ventilation can be improved with the installation of fans.
Room ventilation fans can be of different sizes and shapes. Depending on the size of the room that needs ventilation, a fan of an appropriate size needs to be selected. The CFM of air flow produced by the fan needs to be sufficient to cover the entire area of the room.
