Resideo - Honeywell Home EARD6TZ Fresh Air Damper

Fresh Air Damper EARD6TZ from Resideo/Honeywell Home delivers precise ventilation control for your HVAC system. This round damper, with a single-blade design, fits a 6 inch duct and features a galvanized steel blade for durability and quiet operation in any ventilation system.

Built for reliability, the Fresh Air Damper EARD6TZ uses a 24V AC motor (60 Hz) with 90° travel, offering fast 30-second power-open and 10-second spring-return timing. Designed for reliable HVAC and ventilation applications, mount it on the side or top of your ductwork to suit your installation. Its tight seal keeps static pressure under 1 inch WC, while the low pressure drop (<0.0329 inch WC at 800 FPM) minimizes airflow resistance. The temperature range spans 40 to 140°F, making it versatile for indoor environments.
