The Neff installation accessory HZ9VEDU0 is a mandatory accessory for configurations in exhaust air mode. Four powerful, low-noise acoustic filters ensure significantly less noise and greatly improved psychoacoustics. The sealing gas set can be attached to a flat duct before inserting the element into the device to ensure airtightness. The air outlet on the back of the device can be reached directly with a flat duct element (DN 150).
