12 in Backdraft Damper for Wall Mounting
The Dayton 53DR10 is a 12 in backdraft damper designed for vertical wall mounting. It fits a 12 in fan diameter and requires a 14-1/2 in by 14-1/2 in rough opening. The unit provides a free area of 0.927 sq ft and handles a maximum velocity of 2500 FPM. It is built with a G-90 galvanized steel frame and mill finish aluminum blades.
Straightforward Wall Installation
The shutter measures 17 in by 17 in overall with a frame depth of 2 1/2 in and an open depth of 5 3/4 in. A 1 1/2 in flange and 9/64 in mounting holes allow direct fastening to the wall. Galvanized steel tie rods hold the blades in alignment during operation. The damper opens by airflow pressure alone and closes by gravity when the fan stops.
Verify Opening and Clearance Before Ordering
Confirm the wall opening is exactly 14-1/2 in square so the flange seats properly. Ensure at least 5 3/4 in of clear depth behind the wall for the blades to swing fully open. The unit mounts vertically only; horizontal or ceiling installations will not work. Buyers needing a motorised damper or a larger free area should select a different model.

Questions about this item
How do I confirm the 12 in backdraft damper is opening at the rated 2500 FPM after installation?
Verify the blades swing freely when the fan runs, then measure airflow velocity at the 14-1/2 in opening with an anemometer to confirm it reaches 2500 FPM.
What comes with the Dayton 53DR10 shutter and what must I source separately?
The unit includes the G-90 galvanized steel frame, mill finish aluminum blades and tie rods; mounting fasteners for the 9/64 in holes are not supplied.
Which Dayton 53DR10 size matches a 12 in fan and a 14-1/2 in wall cut-out?
This model is built for a 12 in fan diameter and requires a 14-1/2 in x 14-1/2 in rough opening, so select it when those two dimensions match your installation.
