Does the Zephyr AK6500S have a ducted vent (external vent)?

Yes , the Zephyr AK6500S range hood is a ducted hood , which means it vents cooking air outside through ductwork in your wall, ceiling, or floor. This type is more effective at removing smoke, odors, grease, heat, and humidity compared to recirculating models, and it tends to run quieter since the fan and exhaust path are external.
