30" 600 CFM Contemporary Wall Mount Range Hood - 7' Ceiling Stainless Steel. This model is equipped with LED lighting: (2 lights: 30" - 41", 3 lights: 42" - 53", 4 lights: 54" - 66"). $ Because the Magic Lung blower uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more efficiently than other filtration systems. When comparing the Magic Lung with other blower units made by other manufacturers, use the "Equivalent CFM". # Ratings in accordance with the Standard Test Code by the Energy Systems Laboratory of the Texas Engineering Experiment Station.
