HIGH-QUALITY MATERIALS The calimaero backdraft shutter does not only prevent the outside cold air from entering back into your home but it also helps our environment because it is made of recycled material from Germany. This back draught can be inserted into all exhaust air pipes regardless of the ducting materials. Its plastic and rubber flaps are robust, weather resistant, and environmentally friendly.
PRODUCT FUNCTION The 100mm backdraught shutter is pushed completely into the ducting pipe. Ideal for retrofitting bathroom fans and other ventilation systems without a built-in backdraft shutter. The rubber flaps must be aligned so that they open with the exhaust airflow. The outer rubber ring ensures a perfect seal and a secure hold.
PRODUCT FEATURES Perfect choice for your home improvement. The smooth-running flaps can also be opened by small fans. Its rubber flaps open and close more silently than other metal or plastic models. This will ensure you will not be disturbed by constant annoying rattling from cheaper models.
MULTIPLE USE Perfectly designed for exhaust air systems such as air conditioning systems, tumble dryers, extractor fans, cooker hood, and other HVAC applications. No need to buy multiple products to find the one that works.
