Havells Smoke Spill Motor
Overview
Havells making low-voltage squirrel-cage motors for smoke and heat exhaust ventilators. These motors are mainly designed for driving smoke extraction fans, they can also work under a high ambient temperature atmosphere. These smoke & exhaust ventilation systems create a smoke free layer above the floor by removing smoke and thus improve the conditions for the safe escape for people or protection of the property. They are mainly used in buildings or structures in which smoke control is necessary due to their shape & arrangement.
