## Long description

The CATA B12-PLUS/C E-120 non-return valve is a specialized ventilation accessory engineered to enhance the efficiency of your exhaust system. Designed to prevent backdrafts, this component ensures one-way airflow, effectively blocking cold air, unwanted odors, and dust from entering your living or working space through the ventilation duct when the exhaust fan is inactive.
Advantages
This non-return valve offers a reliable solution for maintaining indoor air quality by creating a physical barrier against external elements. Its durable plastic construction ensures long-term performance and resistance to environmental factors within the duct. By preventing air recirculation, it helps maintain the desired temperature and hygiene levels in your room, making it an essential addition for those seeking to optimize their ventilation setup.
Suitable for

Installation of the CATA B12-PLUS/C E-120 is straightforward and typically involves placing the valve directly into the ventilation duct or at the rear of the compatible exhaust fan. Ensure the unit is securely positioned to allow the flaps to open and close freely with the airflow. No complex wiring is required as it operates mechanically based on the pressure generated by the fan.
What to consider before purchase
Verify the diameter of your existing ventilation duct is exactly 12 cm
Confirm compatibility with your specific CATA fan model
Ensure the installation location is protected from direct moisture exposure due to the IP00 rating
For optimal performance, inspect the valve periodically to ensure that the flaps remain free of dust or debris, which could hinder their movement and affect the sealing efficiency.
