Greenheck’s new IAQ-42 air flow measuring control damper uses a 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 IAQ-42 will control air to prevent over-ventilation, under-ventilation and provide energy savings during low-occupancy periods. Company official claim the damper can help buildings meet the indoor/outdoor air requirements of American Society of Heating, Refrigerating and Air-Conditioning Engineers’ Standard 62 and California Title 24 regulations by providing accurate monitoring and control of outside air. Building projects incorporating the IAQ-42 damper can earn green-building credits for air monitoring, increased ventilation and ultralow leakage, company officials say.
