Key Findings

Based on the overall test findings, lesser known brand Lazer is the top performer and is followed by Usha and Marc. Lazer is also the value-for-money brand. Nine out of 10 brands tested did not meet the requirement of BEE on air delivery – the key performance parameter. Lazer was the exception. However, all brands met the requirement of Indian Standards. Air delivery was found to be less than 210 m3/min except in the case of Lazer. In order to qualify for BEE’s star rating, it is required that air delivery be not less than 210 m3/min. Higher the ‘air delivery’, better the breeze. As per the test results, only Lazer met the requirements of five-star rating in terms of service value (4.46 ), power consumption (48.88 watts) and air delivery ( 218.03 m3/min). It may be noted that higher the ‘service value’, better the energy efficiency and air delivered. Also, lower the ‘power input’, less the electricity bill. All the brands passed in the service value test. All the brands were found to be energy-efficient, consuming between 48.88 watts and 51.25 watts. Only two brands, Lazer and V-Guard, had the ISI mark. However, while both met the requirement of Indian Standards, V-Guard did not meet the requirements of BEE’s five-star rating in terms of air delivery. 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. Orient was the heaviest at 3.586 kg V-Guard weighed the least at only 2.936 kg (motor with blades).
