Price reduced! Thank you for viewing. The Panasonic FY-24J8V is a 240mm ventilation fan with a 100mm pipe diameter, providing efficient ventilation. - Brand: Panasonic - Model Name: FY-24J8V - Size: 240mm - Pipe Diameter: 100mm I purchased this by mistake, getting the wrong size. Unused, in excellent condition. I purchased it from Taroto Denki for ¥11,744 (including shipping). I opened the original cardboard box when it arrived, and I will repackage it in the same box.
