Which Buildings Are Suitable For Fire Exhaust Fans?

With the rapid development of society, fire smoke exhaust fans are now widely used. I believe everyone is familiar with fire smoke exhaust fans. Before, the editor often introduced the functions of fire smoke exhaust fans and what industries they are used in. One industry we cannot ignore is the construction industry. Nowadays, more and more developers are building high-rise buildings in society, but safety issues are missing. Fire smoke exhaust fans can be used in: shopping malls, basements, hotels, cinemas, tunnels, buildings, etc. The fire exhaust fans used in the construction industry can also be divided into many types. So, do you know how to distinguish them? Today I will tell you the following points:

1. Above-ground rooms in factory buildings with a construction area greater than 300m2; Category C factory buildings with a lot of personnel and combustibles, or internal walkways longer than 20.0m in high-rise factory buildings with a height greater than 32.0m; Category D factory buildings with a construction area of any floor greater than 5000m2 ;

2. Class C warehouses with an area greater than 1000m2;

3. Above-ground rooms in public buildings where people often stay or there are many combustibles, and the building area is greater than 300m2; inner corridors with a length greater than 20.0m;

4. Atrium;

5. Places for singing, dancing, entertainment, screening and entertainment that are set up on the first, second, or third floors with a building area greater than 200m2, or on the fourth floor or above, or underground or semi-underground;

6. Underground or semi-underground buildings or basements or semi-basements with a total construction area greater than 200m2 or a room with a construction area greater than 50m2 where people often stay or there are many combustibles;

7. Evacuation corridors with a ground length greater than 40m in other buildings.

The fire smoke exhaust fan is suitable for ventilation or high temperature smoke exhaust in high-rise buildings, underground buildings, tunnels, drying rooms, etc. It can run continuously for more than 60 minutes at a high temperature of 300 degrees Celsius, and continuously for 20 hours/time at a medium temperature of 100 degrees Celsius. Damaged, it is an ideal fire-fighting essential facility! When we use it, we should let it work in a normal working environment, and we must not let it work in a harsh environment. This can easily lead to damage to the exhaust fan. Generally speaking, the smoke exhaust fan should not work for a long time under the condition that the medium temperature is not higher than 5°C, and the high-temperature fire-fighting smoke exhaust fan should not exceed 300°C for a long time. Once a fire occurs, a series of actions will be automatically controlled, and the fan will be switched to high-speed operation to achieve the purpose of fire fighting and smoke exhaust, so that people in the fire area can evacuate in time and safely.
