With the widespread application of 280°C smoke exhaust fire damper products, various problems have arisen during use. Therefore, here are the answers to how to correctly use fire dampers:
Using proper methods to install and use fire dampers can enhance their performance. Fire dampers provide fire prevention functions and are of great significance and practical value for buildings. They are used in many industries and play an extremely important role. In daily scenarios, fire dampers are generally installed in exhaust systems; ventilation and air conditioning systems with partial fans usually connect to air inlets and are normally in an open state. Since fire dampers can perform ventilation functions, they play a crucial role. For pipelines, whether they can withstand high temperatures depends on the temperature control of metal fusible link devices. These devices are used to cut off the current and prevent the spread of fire. When used in ventilation and air conditioning systems, the temperature may rise to a very high level. The key point is that once the temperature exceeds the expected value, the fire damper will automatically shut off to ensure safety. In practical use, regular inspections should be conducted to ensure safety. All parts of the fire damper should be kept in normal condition; if any abnormality is found, it should be repaired promptly. Fire dampers are extremely important safety devices in construction materials, playing a particularly critical role and function, so they must be used correctly. Additionally, their quality is also very important, and high-quality products are required.
When smoke exhaust dampers or fire dampers are located at the ceiling, and smoke is exhausted through the upper space of the ceiling, the following principles should be followed:
- For smoke inlets installed on the sloped ceiling of a closed ceiling, the smoke neck velocity should not exceed 1.5 m/s, and the ceiling should be made of non-combustible materials;
- The opening rate of an unclosed ceiling should not be less than 25% of the net area of the ceiling, and the openings should be evenly arranged.

A friendly reminder from fire damper manufacturers: Exhaust systems, ventilation systems, and air conditioning systems should be installed independently. If used in combination, they should comply with the requirements of the exhaust system.
