Panasonic Ceiling Mounted Ventilation Fan With Motion Sensor

The Panasonic FV-24JR4 is a ceiling-mounted DC motor ventilation fan designed for bathrooms, toilets and laundries, combining quiet, energy-efficient operation with practical automatic ventilation. Its intelligent motion sensor can switch the fan on when activity is detected, making it especially convenient for toilets, powder rooms and shared spaces where users may otherwise forget to operate the fan manually. Three airflow settings provide flexibility for different ventilation needs — 90 and 144 m³/h, plus a high setting of up to 220 m³/h. At the 90 and 144 m³/h settings, Constant Air Volume control helps maintain the selected airflow as static pressure changes within the fan's operating limits, supporting more consistent performance in ducted installations. A built-in 15-minute run-on timer continues extraction after use, helping remove lingering moisture and odours, while the optional 24-hour low-speed ventilation mode provides continuous ventilation where preferred. The built-in backdraft damper helps reduce unwanted air flowing back through the duct when the fan is not operating. With a 100 mm duct connection and 230 x 230 mm ceiling cut-out, the FV-24JR4 is a practical choice for everyday wet-area ventilation when correctly selected, installed and ducted in accordance with Panasonic instructions. It is backed by a 3-year in-home warranty covering parts and labour.
