What is a Window Fan?
An electrical window fan is a fan that’s designed that one may be set in the frame of a window. They can either act as regular fans for ventilating cool air into a room or as an exhaust fan then suck out hot air from a room. It’s a preferred ventilating item at home because the operating cost’s way cheaper than maintaining a central air conditioning system.
Most window fan fit into window frames: still other window fan have expandable panels then cover entire window openings. It’s a must for window fan for covering the entire space of the window in order for maximizing the cooling effect of the window fan. Otherwise, if the window fan’s upon be mounted on a wall, the wall cavity should be very exact in order for accommodating the size of the window fan.
Types of Window Fans
Most window fan have one large fan but there are others which have two fans mounted side-by-side. They have either of 2 or 3 speeds and some models are electrically reversible so the same unit can be used either for intake or exhaust.
Newer models of window fan have built-in thermostats. With a thermostat, you’ll have also set the temperature range you want for the window fan then automatically shut-off. Based on your selected temperature range, if the ambient air near the window fan falls within the temperature range you selected, then the window fan will shut-off.
How to Choose the Best Window Fan
With the varied designs and brands available, it could be quite hard determining which window fan would work best for your needs. So we listed here the things that you’ll be needing keeping in mind when choosing your window fan.
- Air Rotator
Fan blades suck out the air from a room horizontally. Air rotators (as opposed from a fixed fan cover) help direct the sucking function of the air blades from almost all areas of the room, helping the room cool easier.
- Room Area
Before you pick a specific type of window fan, consider first the area you would want thus getting cooled. If it’s a big space with no walls, then consider buying a full-house window fan. Otherwise, for a house with smaller rooms, you might want considering smaller window-fans installed on the rooms where you want cool air circulating.
Window fan is supposed must be working for long periods of time so you would not want your window fan conking on you after just a short time. Therefore, you would want choosing a trusted brand who uses quality materials so you’ll have longer use for your window fan.
- Safety Features
It would be best if your window fan has a cover in front for keeping from having your hands injured when the window fan is in use. It will also be good having horizontal blades at the back of your window fan so you can shut-close when the fan is not in use for protecting your fan motor from getting wet.
- Exact Mounting
Make sure your window fan fits exactly on the size of your window for maximize window fan use. Otherwise, the ability of your window fan sucking out hot air (in case of an exhaust) or pull in cold air (in case of a regular window fan) will be compromised.
- Blade Material
Again, since you would expect your window fan operating for extended periods of time, material parts of the fan heats up fast should be checked. Nowadays, most blade fans are made of plastic. So choose one that’s made of sturdy, high grade plastic. There are window fans that are quiet, convenient, and with reversible airflow.
