Vacu-Stack 6″ TDW Air Cooled With 1/2″ Screen

The Vacu-Stack Air Cooled Chimney Cap is the best solution for wind induced downdrafts. It is designed to fit double or triple-wall, air-insulated, factory built chimneys to stop wind from blowing into the chimney regardless of the wind direction. By accelerating air flow around the Vacu-Stack, flue gasses are forced to flow up and out of the chimney.

This Vacu-Stack Air Cooled Chimney Cap features a unique design that actually increases the draft when the wind hits it as opposed to deflecting it down the chimney and overpowering the draft. A special large 16″ bottom collar rests underneath the cap to keep rain from entering the air-insulated chimney and maintain the proper internal venting that is required.
