The “Engineered Reliability” of
Patented Aprilaire Zoned Comfort
Control Dampers
residential dampers feature a technological breakthrough in damper design. The patented Flexible
design used in Aprilaire dampers eliminates the component most prone to failure in competitor’s
residential dampers…
The simple, yet ultra-reliable design is illustrated below. As the damper motor
rotates the SPOOL, the Flexible Link shortens and the spring-loaded LEVER ARM rotates the blade. When
power to the motor turns off, the spring quietly returns the blade to the open, “Fail-Safe” position. It’s really
that simple.
