There are significant differences in fire smoke and ordinary smoke in many ways. It can be distinguished from the following dimensions:
1. Temperature tolerance: Fire fire exhaust fan uses high -temperature and dual -speed motors, which can work continuously for more than 60 minutes under high temperature conditions at 300 ° C. Ordinary smoke exhaust fan usually works under the temperature conditions of 100 ° C.Therefore, fire smoke fans are more resistant to high temperature than ordinary smoke exhaust fans.
2. Tobacco exhaust efficiency: When fire fires occur, the fire exhaust fan can be automatically switched to high -speed operation through the electrical control system, and the flue gas can be quickly excluded within half an hour.Ordinary smoke exhaust fan is mainly discharged indoors for indoor odors and high temperatures. When encountering high temperature and thick smoke, its smoke exhaust effect is not obvious.
3. Structure and material: Fire fire exhaust fan has a clear structure and material requirements. The shell usually adopts refractory material or steel plate thickened design, and special explosion -proof treatment must be performed to meet the fire protection needs.Ordinary smoke exhaust fan pays more attention to the display of product function, whether it can achieve the purpose of smoking.
4. Price and investment costs: Because fire smoke fan has higher performance requirements and safety standards, its price is usually higher than ordinary smoke exhaust fan.At the same time, fire smoke exhaust fan is not only a tool for ventilation and ventilation, but also a must -have facilities for fire protection, so its investment cost is relatively high.
5. Scope of use: Fire fire exhaust fan is generally used in building places to ensure that the flue gas can be effectively eliminated under emergencies such as fires and ensuring the safety of personnel.Ordinary smoke exhaust fan is more used for conventional smoke discharge needs in building places and production and life.
In summary, there are obvious differences between fire smoke fan and ordinary smoke exhaust fan in terms of temperature tolerance, smoke exhaust efficiency, structure and material, price and investment cost, and scope of use.When choosing to use, appropriate choices should be made according to specific needs and scenes.
The above is the difference between fire smoke exhaust fan and ordinary smoke exhaust fan
