Why Superfan saves more electricity than other BLDCfans

FROM SUPERFAN, INDIA’S FIRST SUPER ENERGY EFFICIENT CEILING FAN

Introduction: Beyond Just Input Power

Many consumers compare BLDC fans based solely on their advertised input
power, which typically ranges between 26W to 35W for a 1200mm BLDC ceiling fan.
However, true energy savings are about more than just input power—factors like
airflow efficiency, power factor, total harmonic distortion (THD), and idle
power consumption also play a critical role.

When Superfan is compared with BLDC fans like Atomberg Renesa, Crompton
Energion, Havells Efficiencia etc, it outperforms most of these efficiency
parameters while ensuring transparent specifications.

1. Airflow Efficiency: Not all BLDCfan's input power are equal

While most BLDC fans in this power range deliver airflow between 210-235
CMM, many manufacturers manipulate power ratings using misleading marketing
techniques:

  • Input power must always be evaluated alongside airflow. A lower power fan may be delivering less airflow, making its efficiency incomparable to a higher power fan with higher airflow.
  • The "5th Speed" Trick: Some brands set the 5th speed slightly lower than the actual maximum to claim lower input power on spec sheets. They then introduce a "boost mode" that consumes extra power to deliver the required airflow.
  • The Reality: Many BLDC fans at 26W-35W deliver airflow between 210-235 CMM, sometimes going up to 235 CMM in a few models.

Superfan’s performance:

  • Superfan's Super Q model is a 25W BLDC fan that delivers 230 CMM, and at 35W it delivers 260 CMM, out performing most BLDC fans in airflow efficiency.
  • Superfan does not use "boost mode" gimmicks, ensuring customers are not confused about what they are getting.
  • Additionally, Superfan also has a 1200mm fan delivering 230 CMM at 35W, proving its airflow efficiency even in higher power models.

Compared to older ACIM ceiling fans that consume 75W-80W while delivering 230 CMM, BLDC fans provide significant energy savings. Even among newer 1-star-rated ACIM fans, which consume 52W while delivering 220 CMM, BLDC fans demonstrate superior efficiency. Many BLDC models can achieve 230 CMM airflow at much lower power consumption, making them a cost-effective choice.

3. Total Harmonic Distortion (THD):Protection for your other appliances

What is THD?

  • High THD can distort the quality of electricity in a home and negatively impact other appliances.
  • Indian standards mandate THD to be below 20%, but lower THD is always better.

Superfan’s THD Advantage:

  • THD in Superfan is less than 5%, significantly lower than the industry standard.
  • Lower THD means:
  • Reduced stress on household wiring.
  • Less interference with other connected appliances.
  • Better overall electrical stability in homes.

2. Power Factor: Saving for All

What is the Power Factor (PF)?

  • Power Factor is a measure of how efficiently an electrical appliance draws power from the grid. The closer the PF is to 1, the less waste there is.
  • Indian standards mandate a PF greater than 0.9 at the highest speed for BLDC fans.

Superfan’s Superior Power Factor:

  • PF is greater than 0.9 even up to the 2nd speed step, and even at the lowest step (1st), it is 0.8.
  • Many other BLDC fans only meet 0.9 PF at the highest speed, and at lower speeds, the PF drops significantly, leading to higher wastage in real-life operating conditions.
  • On average, ceiling fans operate at medium speed (3rd speed step), which for BLDC fans equates to approximately 15W input power. A power factor (PF) difference between 0.8 and 0.93 translates to about a 13% loss of power, equating to roughly 2W per fan. When scaled across 40 crore fans in India, this amounts to a massive national energy waste.

Importantly, in domestic electricity billing, this PF-related energy loss is not directly charged to the consumer—instead, it is absorbed by the government, leading to unnecessary expenditure and inefficiency. Reducing this waste benefits everyone, not just individual users but the entire energy grid and the environment.

Superfan was designed with a higher power factor at all speeds to maximize energy efficiency and minimize wastage. As India's first BLDC fan, we prioritized comprehensive energy efficiency.

What is THD?

  • High THD can distort the quality of electricity in a home and negatively impact other appliances.
  • Indian standards mandate THD to be below 20%, but lower THD is always better.

Superfan’s THD Advantage:

  • THD in Superfan is less than 5%, significantly lower than the industry standard.
  • Lower THD means:
  • Reduced stress on household wiring.
  • Less interference with other connected appliances.
  • Better overall electrical stability in homes.

4. Idle Power Consumption: TheOverlooked Factor

  • Even when a fan is powered but not running, it still consumes electricity.
  • Superfan’s idle power consumption is just 1–1.5 W, ensuring minimal wastage.
  • Many other BLDC fans do not emphasize this factor, leading to unnecessary energy loss over time.

Thus, Superfan Saves More

Superfan’s electricity savings go beyond just input power ratings.

  • Higher airflow efficiency per watt (no misleading "boost mode").
  • Better power factor across all speed levels, reducing waste for the entire grid and benefiting the environment.
  • Lower THD, ensuring better electrical system stability.
  • Lower idle power consumption, preventing unnecessary energy loss.
  • Even when a fan is powered but not running, it still consumes electricity.
  • Superfan’s idle power consumption is just 1–1.5 W, ensuring minimal wastage.
  • Many other BLDC fans do not emphasize this factor, leading to unnecessary energy loss over time.

Frequently Asked Questions (FAQs)

1. Does Superfan save more electricity than other BLDC
fans?

Yes, Superfan maximizes energy savings by ensuring high airflow per watt, maintaining a superior power factor, and having lower THD and idle
power consumption.

2. What is the difference between Superfan and other BLDC fans in terms of airflow?

Many BLDC fans deliver airflow between 210 and 235 CMM, whereas Superfan has models ranging from 210 CMM to 260 CMM while consuming
between 25 W to 35 W. 

3. Why is Power Factor important, and how does Superfan
help?

A lower power factor wastes electricity at the grid level. Superfan maintains a higher PF at all speeds, reducing this wastage and contributing to overall energy efficiency.

4. How does THD affect my home’s electrical system?

High THD distorts electricity quality, potentially damaging appliances. Superfan’s THD is below 5%, much lower than the industry standard of 20%, ensuring better home electrical stability.
