Going by the definition of fan, it is an apparatus with
rotating blades that creates current of air for cooling and ventilation. This
definition remains valid for any type of fan, though different types of
ventilator fans may have different benefits.
Some example of fans and their uses are mentioned below:
Ceiling fans:
These are most commonly used fans around the world. Ceiling
fans are postpone from the ceiling and gives air in the entire room. In most
cases these fans have three blades attached to a centrally fixed motor, which
rotates and along with it rotates the blades, giving air in the room. There are
many verities of ceiling fans too that one can find in the market. Like there
are few with lights and there are few with artistic designs on the blades. Even
the blade sizes differ according to the room. For instance in big churches or
railway stations one may find fans with really big blades. These big blades are
to cover more area with just one equipment.
Table fans:
Unlike ceiling fans these
are not hung from the ceilings instead these are to be kept on a table or a
stand. Table fans have an oscillator gearbox and oscillator shaft, which helps
these fans to give air from one direction to another, covering almost the half
of the room. These are good for small office or personal spaces.
Pedestal fans:
Pedestal fans are
very similar to table fans but these come with an inbuilt stand so that you do
not have to search for a table to keep these fans. Most of the pedestal fans
have wheels at the base, to make the movement smooth. Also some come with an
oscillating head to cover more and large areas.
Tower fans:
These are very sleek model of fans and can fit in small
spaces. These look very modern and produce minimum noise. A very positive point
about these fans is that these fans won’t tip over like other heavy head tower
or table fans.
Wall Mount Fans:
These are copy of
table fans with only difference of it does not require any table and can be
mounted on the wall directly. These are perfect with limited floor spaces.
These are quite powerful fans and usually have two strings attached to increase
the speed and to control the movement of the head. These are apt for
warehouses, factories, garages and alike.
Box Fans:
These are one of the multipurpose fans that can be placed
either on the floor or even in an open window. It helps in clearing stagnate
air.
Bathroom Exhaust Fans:
Ventilation is very
important in bathroom, otherwise the blocked air will create a stink in the
entire house or nearby area. This is good to clear out the odour from the
bathrooms. It also prevents excessive moisture and eliminates other nuisance
caused by this.
Window fans:
Sometimes it is not enough to keep the windows open to get
the fresh air, so to bring fresher and cool air inside, window fans are apt.
These fans save a lot of floor and table space too.
Computer cooling fan:
These types of fans are basically installed inside a
computer device and are fixed to keep the device cool and avoid over heating
Centrifugal fan:
These types of fans
are very commonly used in blow dryers, leaf blowers, air mattress inflators
& other inflatable items like toys and other structures. These are also
used for many industrial purposes.
