Buying Guide for Ceiling Fans in India 2020

Factors that go into the purchase decision of a ceiling fan are as follows: 

Materials used in the appliance

It is important to understand and finalize on the materials that will be used in the making of ceiling fan. Depending upon the time of usage, temperature of the surroundings and the room, dust particles, atmosphere and climate of the area the overall performance of the fan would vary. 

It is important to understand the atmosphere as presence of different chemicals or particulates in the air may react to different materials used in the ceiling fan. 

Depending on such factors the user will have to settle on the type of material of the fan. 

Number of Fan Blades

Ceiling Fans come with all kinds of variations and customization. Some are aimed to be more efficient and some to merely provide aesthetic beauty. 

The traditional fans started with 3 blades but now ceiling fans with 4 or even 5 blades are available. 

The problem with increasing the number of blades is that it compromises air circulation.

But the advantage of having more blades is that it reduces noise. 

So it is a trade-off between better circulation and lesser noise.

Room Size

The fan is supposed to be purchased based on the size of the room it has to cool down. The fan’s blades come of different sizes to suit the requirements of the room. 

For larger rooms some people deploy more than 1 fan while some go with customization and get a fan made with bigger blades to cover the entire room.

Consumers should refer to the term Fan Sweep Size to understand this better. The term denotes the diameter of the circle formed by the fan and blades when operational.

The larger this diameter better equipped for larger spaces to cool. It is pretty obvious that the ceiling fans should be positioned in the centre of the room for maximum efficacy. 

To get a general idea on the size of the room vs the fan sweep size refer the below table. By no means this is ideal but can be used as a general idea to make the purchase decision.

Room SizeFan Sweep Size
< 75 sq ft36 inches
> 75 but < 100 sq ft42 inches
< 100 but < 130 sq ft48 inches
> 130 but < 150 sq ft56 inches
> 150 sq ftCustomized or to use more than 1 fan

Tilt in the blades

Fans have blades but if you have noticed carefully they are always tilted a certain angle. The reason for this tilt is that it creates an angle which in turn creates a downward draught of air. 

The angled blades create pressure difference which is important for air circulation. Flat blades will not work due to this simple concept. 

An ideal tilt angle for a ceiling fan is 12 to 15 degrees. Any angle higher or lower will create a drag effect for the blades which hurts the efficiency of the fan or exert additional strain on the motor of the ceiling fan.


Most of the ceiling fans make noise to some extent. The noise reduces with increase in the number of blades in the fan. But increase in the number of blades compromises the circulation of air in the room. 


Fans are a big part of our day to day activities. Along with tube lights, bulbs and incandescent lights fans are operated throughout the day. So it is not hard to understand that they consume a lot of electricity. 

It is important to understand the BEE rating of the fans before buying them. BEE ratings suggest the electricity saving that the appliance offers.

As these fans will be operational for most of their lives it is imperative for the consumer to buy one that will help them save electricity in the long run.

Even if a model with better BEE rating costs slightly more than the one with lesser BEE rating it is better to go for better model as the difference in price will pay off in the long run in terms of savings on electric bill.


The temperature range in the vicinity in which the fan needs to operate should be kept into consideration while finalizing on a ceiling fan.

The kind of materials used in the fan needs to be capable to withstand the temperature of the surroundings along with the rise in temperature due to the operation of the fan. 

All of these factors needs to be kept in mind to avoid additional wear and tear to the ceiling fan.

Miscellaneous Options with a ceiling fan

Ceiling Fan has not been exactly the same since their inception. There has been tremendous progress in their technology over decades. 

A lot of leading brands have come up with additional customization in their ceiling fans. Some have added lights, some have been added remote to control the fan, pull switches to control the fans and its speed. 

Apart from this the materials of the ceiling fan are also available with anti-dust and anti-corrosion coating. 

Location of Ceiling Fan

It feels pretty straight forward to everyone that the ceiling fan should be in the centre of the room but there’s more to that than just position. 

A normal height of the ceiling from the floor is around 15 feet and normal height of a person ranges from 5 to 6 feet. But for safety reasons you should also another 2 to 3 feet if you are standing on something or raising your arms. 

The fan is attached to the ceiling through a rod which connects or suspends the fan from the ceiling. Therefore it is important for everyone to maintain a minimum height of 8 to 9 feet between the floor the fan. Although this is the minimum height anything more than this is good for everyone.

But there is a myth that the close the ceiling fan is to the ground or the people a better job it does. But as mentioned in this article the fan only circulates the air and in no way cools it. So it is always advisable to keep as much distance as possible between the ceiling and floor. 

In case the height of the room is not adequate one should shorten the mounting rod to maintain a safe distance between the floor and ceiling. And if it is still at a dangerous height and a potential threat it would be better to look at alternatives rather than settling for a ceiling fan.

Different types of domestic fans available in the market

Depending on the purpose that a fan is trying to solve, domestic fans can be classified into various types. They are as follows: 

Ceiling Fan

Ceiling Fans are perhaps the most common type of fan in this list. This fan is almost available in every home and that too in every room. Mostly the ceiling fan is suspended from the centre of the room and the rotating blades cool most of the room down.

It is the movement of these blades that circulates the air and cools everyone down. 

This is a common choice if the ceiling is of standard height and the room size is not too big. If any room is bigger than average size, like a living room, than most people either place two fans or prefer a combination of a ceiling fan and tower/pedestal fan. 

Table top Fan

These are portable fans as they are small in size. They can be placed on any table or firm surface for that matter and turned on. The great thing about such fans is that they are extremely directional. The user can decide and manually adjust the direction of cooling they prefer.

For example if someone is sitting on a chair and working then he can make sure that the table fan is facing him. After he is done and moves to the bed he can then move and place the fan in such a way that it is now facing him lying on bed. 

Another great thing about these fans is that they can be allowed to swing automatically if there are more people in the room. 

For someone who likes to feel the air on their skin all the time then this type of fan is best for them. 

Tower Fans

These are more powerful fans which are shaped like a column and are directly placed on the floor. Most of the tower fans apart from circulating the air come with extra features like air purifier, etc.

They mostly are kept in a corner as they are very powerful in terms of volume of air that they throw. They are generally portable and can be moved around according to requirement. 

Wall Mounted Fans

When the height of the ceiling is a constraint maybe ceiling fans become a risk so people can choose to mount a fan on any of the wall. 

These mounted fans can be made directional or maybe used to swing at an angle for more coverage. 

Generally when there are many constraints in the room like low ceiling height, wiring constraints, etc. people can prefer wall mounted fans.

Exhaust Fans

Exhaust fans are directed towards circulating the air out of the room instead of inside the room. They are used to throw the stale and bad odour air out of the room.

Generally they are used in kitchens and bathrooms. 

Misting Fans

These are pointed towards cooling the air around people using water which are spewed through jets in front of the fan.

These jets throw air in front of the blades of the fan which is then distributed in the surrounding air which cools it down. These fans are targeted to open areas as they can make closed spaces extremely humid. 

Installation tips for Ceiling Fans

Although an electrician is the most qualified to install a ceiling fan but if someone wishes to do it all on their own then you can check the following steps:

  • Refer to the manual guide that comes with your ceiling fan
  • Remember that the ceiling fan does not cool the air but just circulates the air in the room. That means it pushes the air downwards to create a pressure difference and create a draught. There should be a minimum gap of 1 foot between the blades of the fan and the ceiling of the room.  If you are living in a very hot climate then it is advisable to leave a longer space between the blades and ceiling which is around 1.5 to 2 feet. This is to ensure that hot air is not pushed down.
  • To maintain the minimum height requirements one can use a rod based on the height of the room. Certain houses may have slopping roof in which case the user will have to use a bigger mounting rod so that the blades of the fan do not clash with the inclined roof or ceiling. 
  • Make sure that the fan is assembled properly and all the screws are tightly done. Check the mounting rod and all the other attachments beforehand. 
  • Make sure the fan is properly fixed to the mounting column before connecting the live wires. 
  • Switch off the connection by tripping the ELCB or switching off the phase to ensure maximum safety before proceeding to connect the fan with the live wires. 
  • After all the wires are connected to the fan and you are down on the floor only then proceed to test it. Do not test the fan while still standing on the ladder or stool as you may get badly injured from the rotation of the fan blades.

Anyways it seems straightforward to assemble a ceiling fan and place it properly but it is still strictly advisable to refer an electrician who is an expert in such jobs.

Tips on maintenance for Ceiling Fans

  • The blades of the fan should be regularly cleaned. Over a period of time they start to accumulate dust and may become heavy. It might also happen that the dust also falls from the fan on your beds, furniture etc. 
  • The cleaning can be done using a vacuum or a simple damp rag. 
  • The blades of any fan are designed with respect to that fan itself. It is not advisable to interchange it with any other blades as a lot of parameters like the angle of tilt, weight etc. may cause negative effect on the overall functioning of the fan. The motor may become slow due to additional weight and that may reduce efficiency.
  • If there is anything wrong with the fan it is advised to consult an electrician rather trying to inspect it on your own.
  • It might so happen that over a period of time the speed of the fan may get affected. It may slow down. The reason for this can be many. Mostly it will get repaired easily but in drastic cases you may have to replace the fan with a new one. An electrician will be able to provide a better diagnostic and a way forward. 

Fans Working Principle and Types

Fans work on one of the very basic principles of electrical engineering. Fans have a motor at its core which rotates and provides relief to the users from the hot climate of the surroundings. The fans’ motors convert the electrical energy into mechanical energy. 

There are basically 2 different types of fans: axial and centrifugal. Axial fans are also known as propeller fans. 
The axial fans can be further classified into 3 types: propeller, tubeaxial, and vaneaxial.

These fans are generally used as exhausts for ventilation or cooling. The fans in our homes are also a sub type of axial fans. They can be mounted on a pedestal or suspended from the ceiling for cooling our rooms.

But how do Ceiling Fans actually cool the room we are sitting in?

The mechanism behind it is quite simple. The air surrounding us is naturally stratified and automatically regulates itself. Warm air rises upwards as it is lighter than colder air. Ceiling fans just uses this principle and creates a vortex. The blades of the fan suck this air in the top of the room and pushes it down. This makes the air in the room to circulate itself. 

Our bodies on the other hand work naturally to cool ourselves down. We sweat so that the water gets evaporated from our skin thereby reducing the temperature of the body and making us cooler. This is why we sweat when we are hot so that we can naturally cool ourselves down. 

Fans just makes it possible by circulating the air inside the room. This speeds up the process of evaporation so that we cool ourselves down. Fans as the myth suggests do not actually cool the room it just facilitates our body’s cooling mechanism. 

The most important parts of a ceiling fan are Rotors, blades, capacitor, electric motor and flywheel. 

Most ceiling fans have single phase induction motors in them but now another motor known as the BLDC motor have started coming in the ceiling fan. They are more efficient compared to induction motor. These are very efficient in terms of electricity consumed to operate them.

It is imperative to understand this about the ceiling fan you are about to purchase as they are the most operated machines in the house. If they are not efficient and of high quality you will end up with high electric bill.

Also, another advantage with the single phase induction motor is that they are easy to replace and repair. This also brings down the maintenance cost associated with the electrical appliance over long run.

Frequently Asked Questions

Following are some questions which ceiling fan buyers may have based on the research and abundance of brands in this category. We have tried to include as many as possible to provide as much clarity as possible.

Can I use different blades other than the ones supplied by the brand?

It is not advisable to use other blades than the one’s supplied by the brand. The blades weight may vary and that could put more pressure and strain on the motor of the fan. That would in turn affect the rotation speed, draught and overall efficiency of the fan.

Does the fan’s blades rust?

Yes, they do. But if you opt for aluminium and materials like that which are non-corrosive in nature that would increase the life of the ceiling fan.

Do I have to install a regulator as well?

It is important to understand that fans can work on varying speeds. Some fans come with remote control which can do the job. But if the fan does not come with remote then it will become necessary to install an external regulator. But if the person is certain that he/she wants to run it only on one speed then the regulator can be skipped.

Which ceiling is better 5 blades vs 4 blades vs 3 blades?

More the blades on ceiling fan decreases the amount of air being pushed down. But more the blades less is the noise. 3 blades fan are the most famous ones followed by 4 blades fan.
