White colour, 100mm extractor fan with run-on timer for exhaust ventilation of small to medium-sized rooms. Ideal solution for installation in bathrooms, toilets, showers, and other wet places where a Zone 1 fan is required. The modern design of the impeller delivers a high 97 m3/hour extract airflow rate of 25 l/s. Special exhaust air straitening gators deliver low noise, delivering only 25 dBA sound levels. To prevent backflow and heat losses during the fan standby, the fan is equipped with a specially designed backdraft damper.
