BLDC fan savings comparison with old fan wattage BLDC wattage and payback period
BLDC payback is fastest in bedrooms, shops, hostels, and living rooms where fans run for many hours daily.

Replace the longest-running fans first

Do not replace every fan blindly. Start with rooms where the fan runs 10-14 hours a day. A guest-room fan used once a week will take much longer to recover the extra BLDC cost.

Frequently Asked Questions

What makes a BLDC fan consume less power?

BLDC stands for Brushless Direct Current. Instead of an induction motor, BLDC fans use a built-in SMPS (inverter circuit) that converts AC to DC and uses permanent magnets. This completely eliminates rotor copper losses and heat waste, saving up to 60% power.

Does a BLDC fan speed decrease at lower voltage?

No. A major advantage of BLDC fans is that they provide consistent speed even if the voltage drops (e.g., operating perfectly between 140V to 285V).

How quickly does a BLDC fan recover its extra cost?

If you run the fan for 12 hours a day at ₹8 per unit, you save about ₹1,500 per year. The extra ₹1,500 to ₹2,000 you paid for the BLDC fan is recovered in 1 to 1.5 years.
