Frequently Asked Questions
The main function of an exhaust fan is to extract gases and vapors from the environment, providing indoor air renewal.
When purchasing your exhaust fan, remember to check the unit’s dimensions and the manufacturer’s installation guidelines.
When we talk about inline exhaust fans that operate along the duct, multiple exhaust fans can be installed in series, that is, one behind the other. However, this will only increase the air pressure, not the airflow rate. To increase the airflow rate, it is necessary to install one exhaust fan next to another, use duplicate ductwork, or use an exhaust fan with a higher airflow rate.
The installation of the exhaust fan must comply with ABNT 14.518/2020, both in terms of performance, dimensions, and construction characteristics.
A good exhaust system should always provide better air quality while meeting the needs of your environment. If you are unsure which product is best for you, you can contact one of our specialists. We have a specialized team with the technical knowledge required to help you make the best choice.
Energy consumption depends greatly on the type of exhaust fan and the environment in which it will be installed.
Sicflux exhaust fan lines offer the advantage of providing air quality and thermal comfort without increasing your energy costs.
Exhaust fans can be installed in any room where the goal is to promote indoor air renewal, offering greater benefits when installed in kitchens and bathrooms, environments that are more susceptible to airborne bacteria. In addition, they are essential for larger environments, such as industrial facilities and commercial establishments.
