FAQ
The main function of an exhaust fan is to remove gases and vapors from the environment, renewing the indoor air.
When purchasing your exhaust fan, don’t forget to check the unit’s dimensions and the manufacturer’s installation guidelines.
To increase airflow, you need to place one exhaust fan next to another, double the ducting, or use a fan with a higher flow rate. To increase pressure, you should install one fan after the other in sequence.
The installation of an exhaust fan must follow the NBR 16401/2008 standard, in terms of performance, dimensions, and structural characteristics. A good ventilation system should always ensure better air quality, meeting the specific needs of your space. If you’re unsure which product is best, you can contact one of our specialists. We have a trained team with the technical knowledge to help you make the right choice.
Energy consumption largely depends on the type of fan and the environment where it’s installed. Sicflux exhaust fan lines offer the advantage of delivering air quality and thermal comfort without raising your energy bills.
Exhaust fans can be installed in any space where the goal is to promote indoor air renewal. They are especially beneficial in kitchens and bathrooms, and they are essential for larger areas such as industrial and commercial settings.
Yes, the exhaust fan can operate continuously without affecting its expected lifespan.
The difference lies in the airflow rate—that is, the amount of air the fan moves. The higher the number, the greater the air volume it handles, resulting in better air renewal indoors.
