Zephyr DLA-E42ASSX is the 42-inch stainless-steel Layers wall-mount range hood body supplied without a blower. The manufacturer lists compatible blower options selected separately, including a 390-CFM internal blower, 600-CFM internal blower, and 1,000-CFM in-line or external blowers, depending on installation. Features include the Layers multi-plane wall design, with vertical ducting; optional ZRC-00VS recirculation requires the appropriate separately chosen configuration. This listing is the hood body, not a complete blower-equipped ventilation package. Confirm hood, blower, duct and fit requirements before ordering.
