From Superfan, India’s first super energy efficient ceiling fan

The installation location and space of a ceiling fan are as important as choosing the right ceiling fan. The appropriate location and space determine the effectiveness of the ceiling fan. The effectiveness of a ceiling fan is the required thermal comfort, efficiency, quietness.

To get optimal effectiveness from a ceiling fan the following clearances must be taken into account:

Mounting height – distance above the floor level to fan blades tip

Side clearance – distance from the walls/obstructions to fan blades tip

Top clearance – distance in between the ceiling to the rear face of fan blades

The mounting height and these clearances of a ceiling fan ensure occupant safety and satisfaction of the fan performance.

Install ceiling fans for safety and precaution

Ceiling fans shall have a mounting height of at least 7 feet to prevent any accidents caused by clashing with fans. Side clearance of ceiling fans shall be not less than 18 inches to make them rotate without any obstructions.  Also as per the industry standards, the top clearance of a ceiling fan shall be at least 8 inches to avoid ceiling fan starvation that reduces the cooling effect for occupants. For spaces with ceiling heights of less than 9 feet, it is safer to choose low profile ceiling fans instead of ceilings fans with downrod.

Install ceiling fans for effective performance

The occupants get satisfaction from ceiling fans in the form of thermal comfort they experience due to the airflow delivered by those fans. A ceiling fan must be installed in the right location on the ceiling to enhance the optimal airflow for providing the desired thermal comfort for its occupants. The minimal mounting height and clearances might curtail a ceiling fan effectiveness, there are recommended ideal values of those fan placement parameters that shall maximize the effectiveness of ceiling fans.

Ideal mounting height

The ideal mounting height for a ceiling fan to optimally cool occupants ranges from 8 to 10 feet. Choose the appropriate mounting size depending on the fan span size. For safety regulations, ceiling fans with larger span sizes (above 80’’) are recommended to have higher mounting heights of 10 feet or more, since these fan models could be designed to provide maximum airflow even at higher mounting heights.    

Ideal side clearance

The ideal side clearance ranges from 18 to 36 inches according to the span size of ceiling fans. The ideal side clearance for a typical 48’’ ceiling fan to enable proper air circulation and provide voluminous airflow underneath blade swept area is 24  inch.

Ideal top clearance

The thumb rule for top clearance is  0.2 times of  ceiling fans span size, while every ceiling fan must have at least 8 inches distance in between the ceiling to the rear face of fan blades to avoid starving. A 48 inch ceiling fan require an ideal top clearance of 12 inches or more to provide the optimal airflow for occupants.

Install ceiling fans to avoid restricted airflow

In addition to the distance from ceilings, floors, and walls, fan placement must also consider any other obstructions in a space like equipment, furniture, storage racks. etc. which could reduce the airflow effectiveness of ceiling fans.

Installation of ceiling fans in a space with wide and high obstructions should follow at least 3 feet in mounting height and side clearance from the tallest and widest obstruction.

How to install ceiling fans in false ceilings?

Originally false ceilings were made below the original ceiling in the spaces to cover the ducts  of centralized air cooling systems and electrical wires. Today, these false ceilings are used in many modern architectures for aesthetics. If the original ceiling height is not planned to accommodate the false ceiling, it negatively impacts the sufficient clearances of a ceiling fan resulting in reduced fan effectiveness.  Many constructions are not designed for the false ceiling so installing a false ceiling in those spaces hinders with proper installation of appliances like ACs, ceiling fans and lights.

There are two ways to install ceiling fans in spaces with false ceilings, one is by mounting the ceiling fan to the original ceiling (concrete) and another by mounting the ceiling fans to the false ceiling by making provisions to install.

Mounting a ceiling fan to the original ceiling with a suitable opening in the false ceiling is a better solution in terms of safety but suitable care must be taken to maintain aesthetics. Securing the ceiling fans to the false ceiling depends on the material and construction of the false ceiling, it is not preferred by most as the concrete ceiling is designed to handle the load but false ceilings may not. The above recommendations have to be sensibly followed while installing ceiling fans in a space with false ceiling to reduce the hampering performance of ceiling fans.

These guidelines are for installing a standard ceiling fan for typical usage. An individual preference may vary, so it is recommended to utilize these guidelines reasonably to get the best effectiveness from your ceiling fan. Superfan is with a mission to cater to every individual’s preferences through its intelligence of designing ceiling fans to provide superior effectiveness. Superfan manufactures ceilings fans that offers two types of airflow to cater to different preferences of their occupants.
