Download a free DWG fire damper block for ductwork
Download a free DWG fire damper block for ductwork to speed up the preparation of HVAC, architectural, and engineering drawings. This CAD detail is designed to help you produce clean, readable, and professional plan sets while saving time during drafting and project documentation.
The file shows a fire damper installed within a duct and includes the main components typically needed in technical drawings: a metal blade, thermal fuse, access panel, counterweight, spring retainers, and flanged connections. It is especially useful for ventilation systems, fire-rated wall penetrations, public buildings, retail spaces, hotels, and fire safety projects, where clear representation and consistent proportions are essential.
This DWG block is also valuable for improving coordination between architectural layouts, MEP systems, and construction details. It helps teams review positioning, required clearances, possible connection points, and the overall arrangement of equipment within the project.
By using this detail, you can clearly indicate the location of the fire damper and show the components relevant to maintenance access and code-compliant ventilation installations. The block can be moved, copied, scaled, or added to an internal DWG library to match the standards of your design office or practice.
If you need to download a free DWG fire damper block for ductwork, this file can be used in AutoCAD, AutoCAD LT, AutoCAD for Mac, and other software that supports the native DWG format, including BricsCAD, ZWCAD, DraftSight, GstarCAD, progeCAD Professional, nanoCAD, and CMS IntelliCAD.
It can also be imported into BIM and architectural software such as Autodesk Revit, Archicad, Vectorworks, Allplan, and SketchUp Pro, as well as into mechanical CAD and 3D modeling platforms like SolidWorks, Autodesk Inventor, Autodesk Fusion, and Rhino 3D. Free and open-source alternatives such as LibreCAD, QCAD Professional, and FreeCAD may also support it through their DWG or DXF import features.
