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.
To increase airflow, it is necessary to install one exhaust fan next to another, duplicate the ductwork, or use an exhaust fan with a higher airflow capacity. To increase pressure, the exhaust fans must be installed one behind the other.
The installation of an exhaust fan must comply with NBR 16401/2008, 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 expertise needed to help you make the best choice.
Energy consumption depends largely 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 provide indoor air renewal, with greater benefits when installed in kitchens and bathrooms. In addition, they are essential for larger environments, such as industrial facilities and commercial establishments.
Yes, the exhaust fan can remain running continuously without reducing its expected service life.
The difference is the airflow, which is the amount of air moved by the product. The higher this number, the greater the volume of air it moves, resulting in greater indoor air renewal.
