    The main function of an exhaust fan is to extract gases and vapors from an environment, renewing the indoor air.

    When purchasing an exhaust fan, remember to check the unit’s dimensions and the manufacturer’s installation instructions.

    To increase airflow, install exhaust fans side by side, duplicate the ductwork, or use an exhaust fan with a higher airflow capacity. To increase pressure, the fans must be installed one behind the other.

    The installation of an exhaust fan must comply with NBR 16401/2008, including performance, dimensions, and construction characteristics.

    A good exhaust system should always provide better air quality, meeting the needs of your environment. If you are unsure which product is best suited to your needs, you can contact one of our specialists. We have a specialized team with the technical knowledge needed to help you make the best choice.
