The most effective and cost-less way to keep yourself cool is fan, which we have seen most of in our home, office, hotel and commercial places. So you need to check this Fan Buying Guide in this article. Fans circulate the air and maintaining fresh breeze that cools an area as well as keeps humidity levels in check. Fans also have capability of ventilation and prevent inhalation of dangerous gases and fumes.
With such a broad range of fans to choose from, it’s not easy task to choose the right fan according to your needs. There are verities of parameter like fan type, fan size, fan technology etc. So, if you want to clear up on all the technical specifications before making the wisest fan choice possible, you can checking out some points(Fan Buying Guide) following.

How does Fan works?
The fan has motor and it works on the principle of conversion of electrical energy into mechanical energy. At first, the capacitor of the ceiling fan torques up the electric motor and after that it start and run. When we switch on the power of fan, the electrical current reaches the motor and it enters coils of wire that are wrapped around a metal base. Therefore, it creates a magnetic field which further induced force in a clockwise motion. The electric energy is converted into mechanical energy and causes the motor coils to spin along with blades.
Type of Fan
Installation point of view, the fan are divided into ceiling fan, wall fan, table fan, pedestal fan, tower fan and exhaust fan. Click here to know more.
Type of Motor
Fan and their motor are designed keeping in mind the price, style, and performance. While small and inexpensive motors cause the fans to become wobbly and noisy with time. Other hand, fans equipped with large and high-performance motors are much more durable and efficient. In below fan motors are classified in terms of size and capacity.
153 mm: This is an average motor that provides less air movement and may become noisy and unpleasant with time and regular usage.
172 mm: This motor is little bit better than the previous one. It gives better air movement and a good option for small and less used spaces.
188 mm: This motor is good and provides excellent air movement. You will not observe stability or noise issues with fans having this motor.
212 mm: Like the one above, this is an excellent motor that is very durable and sturdy also.
K55: It is slightly expensive motor, its performance is outstanding. Even it is extremely durable.
DC: It is most technologically advanced and energy efficient motors available in the present market ever. They are proven to consume up to 75% less energy while generating high power.
Number of Blade and Pitch
The number of blades on fan is one of aesthetics and personal taste. However, there are slightly differences in performance with the ratio of number of blade in technically. As the number of blades goes up, the fan opts to be quieter and circulates less air. The addition of more blades increase the drag on a ceiling fan’s motor and slow it down. On the other hand, fan with fewer blades can go faster and move more air. It creates little more noise than fan with more blades. Fan having 4-blade and 5-blades, level the ideal balance between the amount of air circulated and amount of tolerable ambient noise.
Blade pitch is the angle and it is measured in degrees between a 180-degree horizontal plane of floor and a ceiling fan’s blade tilt. The air circulation of a fan throughout a room depends on the angle of the blade of fan. The standard blade pitch for a ceiling fan is 12-15 degrees.
Energy Star Rating
It is an important factor to know properly before buying any appliances. It is has good impact on your monthly budget. Higher the star rating and the less in power consumption and vice-versa. You will find the star rating on sticker on appliances.
RPM and CMM
RPM stands for “revolutions per minute”. The terms indicate the amount of revolution of 360° on its axis in every minute. If the RPM is higher, then the spin of fan will be more.
CMM stands for cubic meter per minute which is also referred to as airflow. The measurement is considered on the basis of, when the ceiling fan is on its highest speed and uses both the volume of air and the rate at which it moves. The CMM depends on a few factors like the fan’s motor, the blade pitch and the length and/or shape of the fan blades. Overall the greater the CMM will lead to movement of air more.
The formula of airflow efficiency is the CMM divided by the amount of energy(watt) used to run the fan at its highest speed. The CMM of 75 is the minimum value to make a fan efficient.
Now days you will get so many features on fan like remote control, led light, dust proof, Voice and Apps control, aluminum body, timer, invert support, blade design and style.
Fan are cheap and less maintenance way to keep your room temperature down. So according to your budget you opt features and technology. By reading this article you would have captured most amount of knowledge. So go ahead and BUY accordingly and follow Fan Buying Guide.
