Alno ADU3020N is a versatile kitchen appliance that can be used as a canopy hood or mounted beneath a wall cupboard. It can operate as an exhaust hood or as a recirculating hood. When used as an exhaust hood, it efficiently removes smells and vapors from the kitchen through an exhaust duct. In recirculating mode, the air is purified by an active vegetable carbon filter and then recycled back into the room. The ADU3020N features a user-friendly control panel with four switches and a display. It offers adjustable fan speeds and a high power function for intensive use.
