The MDT line of exhaust fans is designed to seamlessly integrate into existing duct systems, providing essential reinforcement for compact exhaust systems or in environments where noise reduction is a top priority. Made from white ABS plastic—the same material used in household appliances—they combine durability with a clean, compact design that allows installation in a wide range of spaces, even those with limited room.
Installation is discreetly done in the ceiling, leaving only the air intake grille visible. This design is ideal for rigid ducts, ensuring maximum ventilation efficiency.

FAQ
The main function of an exhaust fan is to remove gases and vapors from the environment, thereby renewing the indoor air.
When purchasing your exhaust fan, make sure to check the dimensions of the device and the manufacturer’s installation recommendations.
When it comes to inline exhaust fans that operate along the duct, fans can be used in series, meaning one behind the other. However, this will only increase the air pressure and not the airflow. To increase airflow, you need to place one fan next to another, double the duct, or use a fan with higher airflow.
The installation of the exhaust fan should comply with the ABNT 14.518/2020 standard, both in terms of performance and its dimensions and construction features. A good exhaust system should always provide better air quality, meeting the needs of your environment. If you are unsure which product is best, you can contact one of our specialists. We have a specialized team with the technical knowledge necessary to help you make the best choice.
Energy consumption will largely depend on the type of exhaust fan and the environment in which it is installed. Sicflux exhaust fan lines have the advantage of offering air quality and thermal comfort without increasing your energy costs.
Exhaust fans can be installed in any space where the goal is to promote indoor air renewal. They have greater advantages when installed in kitchens and bathrooms, environments that are more prone to airborne bacteria. Additionally, they are essential in larger spaces, such as industries and commercial establishments.
Yes, the exhaust fan can remain on continuously without reducing its expected lifespan.
The difference lies in the airflow rate, the amount of air the product moves. The higher this number, the greater the volume of air moved, which allows for more efficient indoor air renewal.
