COM­PAR­A­TIVE TEST

Ceil­ing Fans

Only 1 out of these jus­ti­fies the five-star rat­ing

It’s telling that 5 out of the 6 brands tested did not meet the re­quire­ment of BEE’s five-star rat­ing, es­pe­cially in ser­vice value – this be­ing a ba­sic de­ter­mi­nant of en­ergy ef­fi­cacy (higher the ‘ser­vice value’, bet­ter the en­ergy ef­fi­ciency and air de­liv­ered). This find­ing may come as a sur­prise to most of us, con­sid­er­ing that the ceil­ing fan seems to be a very ba­sic, stan­dard sort of prod­uct—one that doesn’t war­rant much thought or re­search. Any model of one of the known brands would do, isn’t it? Keep­ing this gen­eral per­cep­tion in mind, we have in this re­port put the spot­light on en­ergy ef­fi­ciency (and en­ergy ef­fi­ciency is very im­por­tant in the case of a prod­uct used so widely and that col­lec­tively con­sume a huge amount of elec­tric­ity). With the mil­lions of ceil­ing fans sold an­nu­ally in In­dia and the huge amount of elec­tric­ity be­ing con­sumed, think of the po­ten­tial sav­ings in elec­tri­cal en­ergy that can be re­alised with en­ergy-ef­fi­cient mo­tors. So here we are, com­par­ing seven ceil­ing-fan brands with five stars (en­ergy-ef­fi­ciency rat­ing as­signed by Bureau of En­ergy Ef­fi­ciency, BEE, as per which five stars de­note high­est ef­fi­ciency and one star the least) on not just their en­ergy ef­fi­ciency but also their per­for­mance, qual­ity and safety as­pects.

We tested the brands on pa­ram­e­ters such as air de­liv­ery, ser­vice value, power in­put, power fac­tor, volt­age, leak­age cur­rent, tem­per­a­ture rise, creep­age dis­tance and clear­ances, in­su­la­tion re­sis­tance, earth­ing con­nec­tion, de­sign and gen­eral con­struc­tion, sus­pen­sion sys­tem, start­ing and fan speed.

The tests were con­ducted at an NABL-ac­cred­ited lab­o­ra­tory. It should be noted that the Havells ceil­ing fan got jammed and fur­ther tests could not be con­ducted on it.

The samples were tested as per spec­i­fi­ca­tions in In­dian Stan­dard 374–2018 (elec­tric ceil­ing­type fans and reg­u­la­tors). The stan­dard sizes of ceil­ing fans cov­ered in the stan­dard are 900 mm, 1,050 mm, 1,200 mm, 1,400 mm and 1,500 mm. This Con­sumer Voice re­port fo­cuses on 1,200 mm fans – which also hap­pen to be the most com­monly used – with BEE rat­ing of five stars. These fans are the reg­u­lar, non­dec­o­ra­tive mod­els with three blades.
