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, make sure to check the dimensions of the unit and the manufacturer’s installation recommendations.
When we are talking about inline exhaust fans that operate along the duct, multiple exhaust fans can be installed in series, one after another. However, this will only increase the air pressure, not the airflow rate. To increase the airflow rate, it is necessary to install exhaust fans side by side, use two separate ducts, or use an exhaust fan with a higher airflow capacity.
The installation of an exhaust fan must comply with ABNT 14.518/2020, regarding performance, dimensions, and construction characteristics.
A good exhaust system should always provide better air quality while meeting the needs of the environment. If you are unsure which product is best for your application, 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 is installed.
Sicflux exhaust fan lines are designed to provide air quality and thermal comfort without significantly increasing your energy costs.
Exhaust fans can be installed in any room where the goal is to promote indoor air renewal. They offer greater benefits when installed in kitchens and bathrooms, environments that are more prone to airborne bacteria. In addition, they are essential for larger environments, such as industrial facilities and commercial establishments.
Yes. The exhaust fan can remain continuously running without reducing its expected service life.
The difference is the airflow rate, 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.
