curiosities about  fire smoke evacuation fans
we have compiled all the questions about  fire smoke evacuation fans for you. now let's examine all the details together.
smoke ventilation systems designed to effectively remove smoke, heat and combustion products from fire affected areas while simultaneously supporting the system outlet in proportion to external balancing air play a particularly important role in maintaining fire safety.
sections of fire ventilation ducts are also used in pressure boosting systems used to collect and evacuate other harmful and toxic extinguishing gases escaping from fire areas, as well as to control excess pressure causing air discharged after crossing the pressure limit.
types of  fire resistant ventilation systems
ıt is worth discussing the concept of smoke evacuation ventilation, defined in technical terms, which can refer to different types of fire ventilation systems:
a) smoke ventilation systems constructed using exhaust ducts (so-called duct systems) that remove heat and smoke through grilles located in the ventilation ducts. ın this system, there is a clear distinction between a layer of hot smoke at the bottom of the ceiling and a smokeless layer at the bottom displaced by the stabilizing air. ın the revised technical conditions, this solution is the only one that allows the length of emergency routes to be extended;
b) a jet ventilation system that controls the spread of smoke and heat by activating both the exhaust fans in the smoke zone and the fans supplying air to the smoke-free zone, and stops the spread of smoke by creating the appropriate air flow rate;
c) jet ventilation system that immediately activates both the exhaust and supply fans and removes the smoke, preventing the spread of smoke in the entire fire zone, which is limited by the temperature stabilizing air additive.
