They are characterised by quiet operation and high efficiency and reliability. High-quality material ensures the durability of the device, but also maintains its aesthetic qualities. The duct fan is an ideal solution for bathrooms and toilets. It is used to support gravitational ventilation and can be installed in rooms that have individual ventilation ducts, in residential buildings of collective residence and public use, with the exception of rooms where corrosive or explosive atmospheres may occur. HT model - fan with humidity sensor. The HT system has all the functions of the T system, in addition it is equipped with a humidity sensor which allows the fan to be activated if the set humidity threshold is exceeded. The fan is switched on automatically when the air humidity in the vicinity of the fan reaches a pre-set level or when W/WO is activated. Switching off takes place after a set delay time, counted from the moment the required humidity level is reached in the room or the W/WO switch is turned off. A device such as a fan with a humidistat provides us with adequate room circulation and, in addition, maintains the correct humidity level. Construction: Fan made of high quality plastic Installation: Wall mounting For indoor use Fixing with screws Accessories: Moisture sensor with time delay
