I for small kitchens or for island settings where ceilings are too high for ducting, the Zephyr Essentials Series DD1-E36AS Sorrento Downdraft Range Hood rises to the occasion. The brushed stainless steel filter unit houses quiet, efficient centrifugal blowers that clear the air quickly and quietly. An automatic heat sensor adjusts blowers in high-heat conditions and a sleek, clean control knob gives you easy control over an infinite number of speed levels.
