Round Base Chimney Caps
A Solution for Increased Efficiency and Protection
Round base chimney caps improve the functionality and efficiency of chimneys. At FAMCO, we manufacture four distinct round base chimney caps—the Wind Directional Cap, Cone Top Cap, Universal Cap, and Vacuum Cap—each tailored to meet specific needs. Each chimney cap is engineered to enhance airflow, prevent debris and moisture from entering the chimney, and contribute to better overall draft performance.
FAMCO round base chimney caps vents are available in various materials like galvanized steel, stainless steel, copper, and aluminum. We offer multiple styles to suit both residential and commercial ventilation needs.

Technical Information
FAMCO Round Base Caps Benefits
Residential Use:
Essential for homes in areas with strong winds, helping to regulate airflow and prevent backdrafts.
Commercial Use:
The Vacuum Cap is a trusted choice for commercial settings, particularly for gas, oil, coal, and wood-burning systems, where enhancing the draft is a top priority.
Round Base Chimney Vacuum Cap:
Enhances updraft and prevents downdrafts by forcing wind to alter its direction over one of four gores, creating a partial vacuum. Designed for single-wall pipe installation, it features a draw bolt collar for a secure fit.
Cone Top Chimney Cap with Screen:
Designed as an all-weather, seamless cap, it prevents rain and snow from entering the chimney pipe. It mounts over a single-wall pipe and features a fixed base band with a built-in ¼-inch screen.Â
Cone Top Chimney Cap with Screen:
This seamless cap prevents rain and snow from entering the chimney pipe. It is not rated as a spark arrestor, so check local building codes before purchasing.
Proper Placement:
Install chimney caps so that the chimney flue remains protected from debris and adverse weather conditions.
Cap Selection:
Choose caps based on climate and specific ventilation needs. For masonry chimneys, the chimney cap may require additional adapters to transition from the flue to the cap.
Professional Installation:
While some caps may be installed by a homeowner, professional installation is recommended for complex systems or areas with challenging access.
