3960 / 3961 / 3965 / 3967 Insulated Extruded Aluminum Control Damper
The Alumavent 3960/3961/3965/3967 is an insulated extruded aluminum control damper featuring a true thermal-break blade design, suitable for low to medium velocity and pressure exhaust or intake applications. Standard co-extruded santoprene blade and jamb seals provide ultra-low leakage, and the damper is available in both opposed and parallel blade configurations. Optional ELT silicone seals and thermally-broken frame provide maximum performance for extreme low temperature applications.

Additional Notes
The 3960/3961/3965/3967 is AMCA certified, meeting industry standards for control damper performance.
The 3960 series is designed for applications where thermal performance and low leakage are critical, including exterior wall penetrations in cold climates, refrigerated spaces, and building envelope applications subject to extreme temperature differentials. The true thermal-break blade construction and santoprene seals make it one of the highest-performing aluminum control dampers in the Alumavent range for energy efficiency and airtightness. The thermally-broken frame option and silicone seal upgrade extend its suitability to the most demanding low-temperature environments.
