IAQ-42 is an air measuring control damper that utilizes patented Speciflow™ technology.The IAQ-42 will control air to:
• Prevent over ventilation
• Prevent under ventilation
• Provide energy savings during low occupancy periods.The 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 IAQ-42 can help buildings & installation space 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. IAQ-42 meets IECC requirements with a leakage rating of 3 cfm per square foot at 1 in. wg (248 Pa) or less.
The IAQ-42 is provided with a factory-supplied honeycomb air straightener, 24 Vac modulating actuator, air pressure pickups mounted on the damper blades, temperature sensors to allow the controller to correct airflow rate, and factory calibrated controller.
