Resideo ZD20X20TZ Parallel Blade Damper 20"L X 20"H 24V

The Resideo ZD20X20TZ is a parallel blade damper that is intended to regulate air in HVAC systems. This 24V motorized damper has dimensions of 20L x 20H and is suitable for medium sized ducts. The parallel blade design, constructed from robust aluminum, ensures that little air escapes when the blades are shut and the air is efficiently distributed when the blades are opened. The damper consumes only 8 VA power and therefore provides energy efficiency without compromising reliability. The damper’s motor is spring-return; in other words, it reverts to the initial position in the event of power loss, thus increasing the system’s dependability.
