The Combi Air features an aerodynamically compact design, making it ideal for ventilation and exhaust ducts.
The design harnesses wind power to create upward wind pressure, drawing exhaust gases out of the duct. Backflow of exhaust gases is prevented or minimized. Thanks to its aerodynamic design, the chimney cap functions effectively regardless of wind direction.
Under normal conditions, the chimney cap provides optimal protection against any form of precipitation for your ventilation and exhaust ducts. This prevents wet spots on the wall, wet ducts, and frost damage.
In addition to protecting against rain and backflow of exhaust gases, the chimney cap also safeguards your ventilation and exhaust ducts against bird nests and other blockages.
