36 in backdraft damper for wall mounting
The Dayton 53DR14 is a 36 in backdraft damper designed for vertical wall installation. Its extruded aluminum frame and G-90 galvanized tie rods suit commercial or industrial ventilation systems that need automatic airflow control. The unit fits a 39-1/2 in by 39-1/2 in rough opening and provides 8.995 sq ft of free area.
Airflow performance up to 2500 FPM
The shutter operates at velocities up to 2500 FPM without powered assistance. Gravity-activated blades open when the fan runs and close when it stops, preventing backdrafts and reducing noise from wind infiltration. No electrical connection is required for the damper mechanism itself.
42 in square flange with 1-1/2 in mounting surface
The overall frame measures 42 in by 42 in with a 2-1/2 in frame depth and 5-3/4 in open depth. Mounting holes are 9/64 in diameter on a 1-1/2 in wide flange, allowing direct attachment to masonry or framed walls. The vertical orientation and wall-mount design leave interior floor space clear for equipment or ductwork.

Questions about this item
How do I mount the Dayton 53DR14 shutter in the 39-1/2 in x 39-1/2 in wall opening and which step is often missed?
Fasten the 42 in x 42 in extruded aluminum frame through the 9/64 in mounting holes; the step often missed is verifying the vertical mounting position so gravity closes the blades.
What maintenance will the G-90 galvanized tie rods and aluminum frame need over time?
Inspect the tie rods and blade pivots annually for corrosion or binding; lubricate pivots with light machine oil if movement stiffens.
At what airflow limit does the damper reach its maximum rated velocity?
The damper is rated for a maximum velocity of 2500 FPM; sustained flow above this can cause blade flutter and excess pressure drop.
