FAQ
The main function of an exhaust fan is to extract gases and vapors from the environment, promoting indoor air renewal.
When purchasing your exhaust fan, be sure to check the unit’s dimensions and the manufacturer’s installation recommendations.
To increase airflow, exhaust fans should be installed side by side, or you can double the duct size or use a higher-capacity fan. To increase pressure, they must be installed in sequence, one after the other.
Exhaust fan installation must comply with NBR 16401/2008, regarding both performance and construction standards.
A good exhaust system should always ensure better air quality, meeting the needs of your environment. If you’re not sure which product is right for you, you can reach out to one of our specialists. We have a trained team with the technical knowledge to help you make the best choice.
Energy consumption will largely depend on the type of exhaust fan and the environment where it will be installed.
Sicflux’s line of exhaust fans offers the advantage of improving air quality and thermal comfort without increasing your energy bills.
Exhaust fans can be installed in any room where air renewal is desired – they offer even greater benefits when used in kitchens and bathrooms. Additionally, they are essential for larger spaces, such as industrial settings and commercial establishments.
Yes, the exhaust fan can remain continuously on without reducing its expected lifespan.
The difference lies in the airflow rate – the volume of air the fan moves. The higher the number, the more air it moves, and the greater the indoor air renewal.
