What is EI fire-proof smoke exhaust duct?<\/strong><\/b><\/h2>\n

Fire-resistant smoke exhaust ducts, also known as fire-resistant ducts, have the same function as normal ducts. This is one of the extremely important main parts of ventilation and air conditioning systems, supplemented with fire-resistant materials so it is fire-resistant.<\/p>\n

Ventilation fire ductwork:<\/strong><\/b><\/h2>\n

Fire-resistant ventilation systems are used sparingly to prevent the spread of fire in the event of a fire.<\/p>\n

Fire can be prevented from spreading between different compartments through stairways, corridors and rooms, if the building materials and construction components have the same fire resistance and fire resistance classification.<\/p>\n

It is necessary to carefully consider the technical parameters to choose the duct with fire resistance standards suitable for the system. Ordinary metal ducts cannot meet fire resistance standards, if only using metal ducts, in some cases, metal ducts can melt, deform and accelerate the spread of fire and smoke. Fire-resistant ducts meeting EI standards are the most suitable choice for this system.<\/p>\n

Smoke extract fire ductwork:<\/strong><\/b><\/h2>\n

The emergency smoke exhaust system is responsible for directing smoke and toxic gases from inside the building to the outside in case of a fire. At the same time, it directs fresh air from outside into the ventilation system. The fire-resistant air duct will ensure that the system operates stably in the event of an incident, maximizing the amount of smoke that can be removed from the building, helping to keep the fire area smoke-free so that residents can escape. At the same time, it improves the fire prevention and fighting capabilities of the building.<\/p>\n

This system is often used in transportation complexes, shopping malls, offices, apartments, basements\u2026 especially basements with low ceilings.<\/p>\n

Pressure ductwork:<\/strong><\/b><\/h2>\n

The pressurization system limits the infiltration of smoke into certain critical areas of the building by ensuring that the air in those areas has a higher pressure than the surrounding areas. The system is often applied to stairwells, corridors, etc. It has the effect of removing smoke from the installed area, helping people inside to evacuate more easily.<\/p>\n

Since the air supply that creates the pressure must be maintained throughout the duration of the fire, Fireproof duct<\/b> should be used to ensure the booster system operates stably until the fire is over.<\/p>\n
