The Straightline Series is a classic design that works well in any kitchen. This hood is available with halogen lights. Transition to 8" round included with each dual blower. Equivalent CFM: A typical hood with a 600 CFM Magic Lung blower is capable of handling professional style cooking equipment with 900 CFM requirements (as specified by the range manufacturer.) The Magic Lung blower performs better because it uses centrifugal filtration instead of mesh or baffle filtration. NOTE: Hoods pictured above have optional duct cover extensions. Duct covers are available in standard heights.
