NEW Adjustable Pressure Controller (APC) option for Pottorff's Backdraft Dampers most often specified for use in Warehouses and Data Centers. The APC can be adjusted to allow our dampers to open at a higher maximum set pressure, making it easier to adjust the damper opening point.
Backdraft DampersThese Airflow Measuring Stations provide you with precise airflow measuring along with an integrated control damper in one easy-to-install assembly. Each station is supplied with a steel airfoil or aluminum airfoil blade low leakage control damper and modulating 24V actuator to allow building control systems to precisely regulate airflow and improve overall indoor air quality based on real-time airflow measurements.
Airflow Measuring StationsThe CFD-521-BT employs butterfly style blades for point-of-origin control of radiant heat in HVAC systems. The 45-degree collar installation option makes duct connections much easier in tight spaces where access to the top of the damper is restricted.
CFD-521-BTDuring the Covid-19 pandemic and into the recovery phase, schools are vitally aware of the need to provide energy efficient fresh air intake and exhaust. With the CARES and CRRSA bills, the U.S. government has now approved more than 100 billion to support upgrades to critical school infrastructure such as improvements to HVAC systems and indoor air quality.
