Crompton Energion Hyperjet 1200mm BLDC Fan Review: Fast and Fair

The Crompton Energion Hyperjet 1200mm suits households that want a BLDC fan with plenty of punch and a brand whose technicians turn up in most towns. The compromise is noise: at top speed it is audible in a silent bedroom, and some owners report electronics faults after the first year.

How strong is the airflow in a living room?

Air speed at 1.5 m below the blades measured 2.2 m/s at top speed. Hyper mode, a boost setting on the remote, pushed this to about 2.5 m/s for the cost of roughly 44 W. In a 14 by 12 ft living room it handled afternoon heat on the fourth speed without needing the boost. The three blades are on the broad side, which helps move air at lower rpm.

How much does it save compared with an old fan?

At top speed it drew 36 W, against 75 W for a standard induction fan. At 12 hours a day and ₹8 a unit, that saves about ₹1,367 a year per fan. On the middle speeds it used 15 to 20 W, which is where most people run a fan at night.

Will the Crompton Hyperjet run on an inverter?

Yes, with good margin. On a 900 VA inverter with a 150 Ah battery and two LED bulbs, it ran about 18 hours at top speed. The inverter did not complain about the load, and the fan restarted on its own after a grid switch-over, with a one second pause. Induction fans on the same setup last about half as long.

Is the Crompton Hyperjet noisy?

It measured about 52 dB at one metre on the top speed, which is a steady whoosh with a faint electronic whine at certain speeds. Lower speeds are quiet enough for a living room TV. Light sleepers should try the Atomberg or Havells instead.

How does it behave on 180 V?

On our stepped supply, speed held until about 190 V and then dropped slightly. At 180 V the fan still ran and recovered when we raised voltage. At 250 V it did not heat or buzz. No stabiliser was needed.

What do owners complain about?

Reviews on retailer pages for Crompton BLDC fans praise the savings and the remote, and the recurring complaints are remote or control-board failures after a year or two, and one-off defective units. We did not see a fault in five weeks. Keep the invoice, as the warranty is 2 years on most listings.

How long does it take to install?

Around 30 minutes for an electrician with the supplied down-rod. For ceilings above 10 feet, ask for an extended rod. In monsoon-damp rooms, dust settles on the blades quickly; wipe them with a dry cloth every few weeks to avoid wobble.

Who should buy something else?

Buyers who want the quietest fan should pick the Atomberg. If a long warranty matters, the Superfan carries 5 years.

Does Hyper mode add to the electricity bill?

Only while it is on. We used it for short bursts in the afternoon, and the extra draw of about 8 W over the top speed adds little over a day. Leaving it on overnight is not necessary, since the sleep mode on the same remote lowers speed gradually and saves power.
