Simply the perfect solution against humidity in the bathroom. The Fan 1500 DH is equipped with a moisture sensor that you can set in the range between 40 and 90% relative humidity. The fan automatically turns on as soon as the humidity exceeds the set threshold. This adds comfort and helps prevent mold growth in the bathroom. You can easily turn the fan on and off at any time using the bathroom light switch. Additionally, by setting it once, you can specify a run-on time, so the fan continues to operate for up to 30 minutes after the bathroom light is turned off and then automatically shuts down. The fan features a modern Bosch design with an easy-to-clean plastic front, making it a perfect match for any bathroom decor.
