4" to 3" Velocity Cone

Evaluated to UL1738 and ULCS636 by ICC, InnoFlue’s lightweight velocity cone is designed to improve the flow of exhaust gases as they exit exhaust system facilitating smoother and more efficient exhaust gas flow. The cone's tapered design improves the flow of exhaust gases to as they pass through the exit. InnoFlue’s polypropylene velocity cone provides key benefits such as improving the exhaust system’s overall efficiency through reduced backpressure by optimizing the exhaust flow.
