An extractor fan with shutters is primarily used for ventilation purposes where controlling airflow and preventing backdrafts is important. Here are its main uses:
Kitchen Ventilation: Removes cooking odors, smoke, and moisture while the shutters prevent outside air, dust, or insects from entering when the fan is off.
Bathroom Ventilation: Helps reduce humidity and prevent mold growth, with shutters closing to block drafts from outside.
Industrial or Workshop Settings: Used to expel fumes, dust, or hot air, while the shutters protect against reverse airflow
Pest and Weather Protection: Shutters keep rain, wind, and insects from entering the building when the fan is not operating.
Extractor fans with auto-closing shutters are ideal for environments that need both active airflow and protection when the fan is inactive.
