Mitsubishi Electric (MITSUBISHI) Duct Fan, Ceiling-Mounted, [Intake Type] Connection Pipe: φ150mm, Mounting Hole Size: 395mm square. This item was installed for display purposes for about six months and then removed, so it has hardly been used and is still in good condition. Since it's all 150 φ, it has a large capacity, allowing for more reliable air circulation than simply relying on natural intake. The wiring has been cut near the power connection terminals to prevent damage, so please remove the old wiring and insert new wiring for use.
