The IAQ-42 airflow-measuring control damper utilizes patented Speciflow™ technology built into the controller to measure the pressure, position of the damper blades, and temperature of the air flowing through the damper. The control damper will control air to prevent overventilation, underventilation, and provide energy savings during low-occupancy periods. It can help buildings meet the indoor/outdoor air requirements of ASHRAE Standard 62 and California Title 24 by providing accurate monitoring and control of outside air. Building projects incorporating the IAQ-42 damper can earn LEED-EB credits for air monitoring, increased ventilation, and ultra-low leakage, says the company. The control damper offers a leakage rating of 3 cfm per square foot at 1 in. wg (248 Pa) or less.
