PASSAGE
The Bureau of Indian Standards (BIS) does not specify any standards for domestic exhaust fans. Therefore, none of the models tested carried the ISI mark. CERS tested the exhaust fans for power leakage, insulation resistance, earthing continuity, electrical input and protection against direct current. All of them were found to conform to the safety requirements for commercial or industrial purpose ventilating fans set by the BIS. Usually exhaust fans are fitted with an external guard (grill or mesh).Such guards are useful to prevent accidental contact with moving parts of the fan. The tests revealed that though all the models tested conformed to the to safety tests, their air delivery and electricity consumption differed widely and hence, their service value also varied. Consumers should make a conscious decision depending on their need. For small spaces, an exhaust fan with high service value would be best because such a fan will give you sufficient air delivery with low energy cost. But for bigger spaces perhaps you wouldn’t like to compromise with the air delivery of the fan, even if it adds a little more to your energy bill.
