VENTILATION

BAN thermostatic bypass with special damper and metal filter is used to prepare air coming into the hot air ventilator. It protects the hot air ventilator from overheating (when motor is not working, for example due to a lack of electricity) by shutting the valve and ejecting air through a damper to another room. Bypass also stabilizes temperature in the system, by opening a damper and sucking cool air, when the air coming into the ventilator is too hot. Bypass is also equipped with a metal filter.
