Application and Design
The SEBR-10 series is a severe environment 316 stainless steel eccentrically pivoted backdraft damper for low velocity
systems. SEBR-10 series is a horizontally mounted damper and designed to allow vertical airflow up and prevent reverse
airflow. On-blade counterweights are provided to fine tune start-to-open and full open blade operation. Ball bearings minimize
friction.
Recommended Applications:
•
Gravity hood intake and exhaust
• Stairwell pressurization
• Room pressurization
• Ductwork outlets
Poor Applications:
• Propeller fan outlets (high velocity)
• Centrifugal fan outlets (high velocity)
• Building pressurization (sensitive to wind)
• Pressure relief exceeding 0.13 in. wg (32 Pa)
