The TEF-S is equipped with a measurement pin for easy and precise airflow measurement, unlike standard valves. Combining silence and flexibility in a seamless package, the solution is perfect for both air supply and extraction in circular duct systems.
Why is this so useful? With the measurement pin, you can immediately see the pressure drop Pa (in this case 18 Pa). By using this value in combination with k-factors, you can quickly calculate the airflow m³/h. For more parameters, simply visit design.systemair.com. Select the product size and position, enter the calculated airflow value, and access all key data, including throw length m, sound power level dB(A), and more!
The TEF-S air valve combines silence and flexibility in a seamless package. It is the perfect choice for both air supply and extraction in circular duct systems, making it an excellent fit for residences, offices, hotels, and any environment where comfort and dependability are paramount.
