Jaya Marriage Hall, Telangana, India.

A Case Study : Epoch HVLS 16-ft Fan By Falco eMotors Inc.
Report No. 040420-02



  1. Jaya Marriage Hall is a convention hall for big wedding ceremonies, entertainment events, social events, formal meetings, and corporate gatherings.
  2. Since the hall is in the middle of the city, there was a problem of air movement therefore guests feels uncomfortable during summer season.

  3. The deep plan space of the hall need a large air circulation so that adequate fresh air would reach all occupants.




  • Epoch 2.0, 16-ft 03 Fans was installed with the following specifications ;
    • Motor: Epoch 2.0;
    • Coverage Area: 12000 Sq. Ft. (1,114 Sq. m);
    • Speed: 95 RPM;
    • Peak Power: 1.1kW/1.5 hp;
  • Epoch 2.0, 16-ft Fan is one of our most popular fans with amazing airflow and airflow efficiency.


Site Survey:

A site survey is mandatory before any HVLS fan recommendation. The survey revealed the following dimensions:

  • Total Area: 250 ft X 85 ft = 21,250‬ Sq. ft.
  • Floor to Ceiling Distance: 22 to 25 ft
  • By a rule of thumb distance/1.5 gives us the approximate fan diameter. 
  • In this case, we chose to go with a 16-ft fan.

Test Reports:

Three test reports are collected for each fan installation as follows:

  1. Power Consumption Report;
  2. Input Current Report;
  3. Air Flow Report.

Those reports are shown for this site:


Power consumption report captures the real as well as apparent power. Epoch HVLS fans are the only fans in the world to have active power factor correction and unity power factor. Therefore the Watts (Real Power) and VARs (the apparent power) are almost the same. The power has been captured at 55, 65, 75, 85 and 95 RPM. Power drawn at those speeds are 440, 590, 710, 860 and 980W respectively. The chart above also shows trend lines generated using Excel for real and apparent power to take into account any measurement errors as fan power consumption can be modeled by well known equations.


The input current is also measured at 55, 65, 75, 85 and 95 RPM. Input current is recorded as 1.9, 2.6, 3, 3.9 and 4.7A respectively. The input voltage varied from 240 to 244V during the measurement. 


The airflow is measured from the center of the fan and is recorded at every 3-ft distance. Values were recorded upto 30-ft from the center of the fan. The values were respectively, 310, 344, 394, 551, 531, 511, 492, 472, 413, 351, 320, 260 ft/min at distances of 3,6,9,12,15,18,21,24,27, 30, 33  and 36-ft respectively.


Estimated Yearly Savings while Using Epoch HVLS Fans


Epoch 16-ft fan was compared against Indian HVLS fan Manufacturer. Based on their data sheet, daily, monthly and yearly power consumption and costs were calculated. An Epoch HVLS fan will save the end user anywhere from $1,588 to $6,713 per year over any competitive brands because of its unique technology.
