The Renaissance raised ventilation System offers the power you need to effectively remove smoke and cooking fumes from your kitchen at the touch of a button. There's no need to block views by suspending a large island hood from your ceiling because this innovative vent lives discreetly under your counter surface when not in use. When needed, it rises 15" above the countertop to efficiently remove smoke and odors. Then, the quick touch of a button sends it back down below your counter surface for an unobstructed countertop. The Renaissance Raised Ventilation System is perfect for island, peninsula or wall installations.
