1) Indian manufacturers need to put in extra efforts to improve air delivery and service value in order to enable consumers to realise optimal energy savings. Overall, only one brand, Lazer, qualified for BEE’s five-star rating. The remaining nine were found lower on air delivery. 2) There is scope for making ‘super efficient’ fans by bringing down input power by 5 per cent to 10 per
cent. 3) A regulator should be capable of reducing the speed of fan to at least 50 per cent. However, none of the 10 brands provided a standard speed regulator compatible with the fan, often leading to usage of sub-standard regulators by users and thereby possibly affecting the fan’s performance.
