While Bosch’s line of Kitchen Ventilation Systems range in style from traditional to very contemporary, their performance and efficiency remains steadfast. Like all Bosch kitchen appliances, Bosch Vents and Hoods are made with the finest materials and are engineered to capture and eliminate the harshest cooking odors and steam. And with Bosch’s new recirculation downdraft vent system, Bosch vents require no ducting. Bosch’s complete line of vents and hoods includes Bosch 30-inch and 36-inch Under Cabinet Hoods; Bosch Chimney and Island Hoods ranging available as 30-inch, 36-inch and 40-inch hoods; and Bosch Custom Ventilation Inserts available from 30-inch to up to 36-inch vents. Every Bosch Vent and Hood is designed for quiet operation with 400 and 600 CFM blowers, and easy upkeep with dishwasher-safe filters.
