The FAMCO WDC Wind Directional Chimney Cap is designed to be most effective. The FAMCO research team has proven that the most effective draft inducing chimney caps are those that separate the wind stream as it flows over the cap and those that rotate to align with the wind direction. The Wind Directional Chimney Cap – WDC – does both to provide maximum drafting. In usage, the rotating hood is kept in proper position (relative to the wind) by the wind vane. Air movement past the hood creates a partial vacuum in the flue, enhancing draft efficiency and helping to prevent downdrafts. Quality constructed in 26 gauge Galvanized steel. The FAMCO WDC Wind Directional Chimney Cap is engineered to slip around the O/D (outside diameter) of a single wall pipe and with the help of an adapter (WCASS) fit inside an insulated, double or triple wall pipe. Comes in a range of diameters from 5″ to 14″ with heights ranging from 14½ inch to 27 inch respectively. The FAMCO WDC Wind Directional Chimney Cap is manufactured by Famco in the United States and comes with a 1-year warranty against product defects and workmanship.

GREAT product!
i was forced to run my stove pipe up on a steep part of a gambrel roof. when winds would come from the north, I would get MASSIVE downdrafts. After installing this chimney cap, the drafts were GREATLY minimized and i’m able to have wood burning fires on any day, regardless of the wind direction. Truly a great product and great value.

This wind directional cap is ingenious. It works like a charm. For my application, however, it turned out not to be a great solution….and this is where FAMCO shined! I made an inquiry about an alternative product; Within that day they had reviewed my inquiry, presented a sensible and appropriate solution, and placed a new order under warranty, which was more than they really had to do. The replacement product arrived in three days and it has solved the issue and is performing perfectly! Three cheers for this company and the fact that they gleefully stand behind their products!

wind cap moves nice and freely and service was great. l bought it to use on a wood burning tent stove when camping. Had a first time desert camping with heavy winds blowing the smoke back down the stove pipe. looking forward to tiring it.
