Whether you are a first-time fan buyer or are planning to replace your old ceiling fan with a new one, you should always do a little bit of research before you buy a ceiling fan online. Make sure you ask all the relevant questions that are there to ask. And just in case you aren’t sure as to what to ask here are a few questions and their answers to give you an idea of the questions you can ask when looking for a ceiling fan. These are some of the most frequently asked questions that most people ask before buying a ceiling fan.
1. Air Delivery
Air delivery, also referred to as air supply or airflow, is the amount of air the fan moves in a minute. It is measured in CMM (Cubic Meters per Minute). The more air the fan displaces, the cooler the room will be. Air delivery of 230 CMM is considered good.
2. Power Consumed
The Power consumption of a ceiling fan is an important criterion to consider. It directly influences your monthly electricity bill charges. The power consumption is measured in Watts. The higher the wattage, the more electricity is consumed. Hence, purchase an energy-efficient ceiling fan. Some brands promise low power consumption up to 40 percent. You can choose according to your needs.
3. Fan Speed
Fan speed is measured in RPM (Rotations Per Minute). Ceiling fans rotate at different speeds. The speed of the fan directly contributes to the cooling efficiency. Based on the speed, ceiling fans are of two types: High-Speed Fans & Normal Speed Fans. High-speed fans run at 370-380 RPM whereas a normal speed fan runs at 330-340 RPM. High-speed fans ensure improved air quality and consume less power.
The sweep size, also referred to as blade sweep or blade span, is the diameter of the circle formed when the fan is set in motion. It helps determine the air delivery of the ceiling fan. The higher the sweep size, the more the air delivery, the better the cooling capacity. The sweep size depends on the size of the room. Thus, measure the dimensions of your room – and choose the right sweep accordingly.
Ceiling fans in India are available in the following sweep sizes:
The right sweep size would depend on the size of your room. Selecting the right sweep is essential not only in terms of performance but safety. For instance:
Brands use different types of materials to manufacture ceiling fan blades. Fan blades come in Aluminum, sheet metal, and wooden materials. Of these, Aluminum is the best. Aluminum blades are aerodynamically designed. This helps them cut through the air more effectively. Besides, they are lighter in weight. This allows fast movement and improved cooling. Sheet metal and wooden materials, on the other hand, are not so effective. Sheet metal is prone to rust and corrosion whereas wooden blades tend to swell up – due to imbibition. Thus, choose aluminum metal blades for a sturdy and long-lasting performance.
Ceiling fans come in 3, 4, and 5-blade options. Of these, 3 blades work the best (especially in Indian climatic conditions) where you need a higher air delivery. The 4-blade and 5-blade fans run at lower speeds – and are mostly installed for aesthetic purposes. You can choose the number of blades according to your requirements.
The length of the down rod depends upon the height of your room’s ceiling. It is responsible to provide adequate air delivery – and ensure safety. To deliver optimal airflow, the down rod size should be approx. 9 to 10 inches. Concerning safety, the down rod size should be around 7 to 7.5 feet above the floor. For higher ceilings, it should be 8.5 feet or so.
One of the main factors to consider when buying a ceiling fan is the brand that you buy from. Make sure you buy from a brand that has a reputation for manufacturing quality products and offering excellent after-sales support. One such brand that you can look at for buying a ceiling fan or any other home electrical is Luminous India.
