Famco GVC1224 - 12" Galvanized Vacuum Vent Roof Cap
The Vacuum Cap works by forcing the wind to alter its direction over one of three gores on the cap. This change of direction creates an area of lower density air (partial vacuum) at the outlet of the pipe. This lower density air creates draft within the exhaust pipe, helping to remove exhaust gases. The positioning of the cap relative to the prevailing winds is not critical but is slightly more effective when placed with its flat side facing the winds.
