The IAQ-42 is an aluminum airfoil blade damper that utilizes Speciflow™ technology with integral airflow monitoring and control capability. This air-measuring control damper helps buildings meet the minimum outdoor air requirements of ASHRAE Standard 62 or California Title 24 by providing accurate monitoring and control of outside air. The damper has a rated accuracy of ±5 percent of reading for face velocities of 300 to 2,000 fpm. It has a leakage rating of 3 cfm per ft2 at 1-inch water gauge. Features include temperature compensation for changes in air density, 1-minute response to pressure changes and set point changes, a 24-VAC modulating actuator, and programmable controller.
