Abstract (en)
[origin: EP2835591A1] The present invention relates to a hood system having a built-in rotor, capable of discharging contaminated gas generated by a source of contamination in a timely manner so as to prevent the contamination of indoor air in advance. The hood system having a built-in rotor comprises a housing, an exhaust fan, said rotor, and a discharge unit. The housing is arranged on top of the contamination source, and the lower side thereof has an inlet port for feeding in contaminated gas. The exhaust fan is arranged inside the housing, and rotates by means of a rotation-driving device so as to forcibly exhaust the contaminated gas. The rotor rotates together with the exhaust fan to prevent the contaminated gas from diffusing into an indoor area. The discharge unit is arranged on an upper surface of the housing so as to discharge the contaminated gas suctioned by the exhaust fan to the outside.
