Model DFD-210 is a dynamic rated multi-blade fire damper with 3V style blades. The DFD-210 may be installed vertically (with blades running horizontal) or horizontally and is rated for airflow in either direction. This model has a manual quadrant which allows the DFD-210 to function as both a fire damper and a manual balancing damper. W x H Minimum

The F-B90 multi-blade fire damper provides efficient passive fire protection in a range of installations. It’s designed to utilize compartmentalization to prevent the spread of smoke, fire and toxic gases. In the event of a fire, when the air in the duct exceeds 72 °C or 74 °C, the thermal fuse will melt in both the actuator and manual ...
