The smoke exhaust fan is mainly used to remove the smoke in the fire area at the early stage of the fire, to prevent the fire from spreading to other areas with the smoke diffusion, and to ensure the evacuation of internal personnel!
Performance characteristics:
1 and HTF series fire-fighting high-temperature smoke exhaust fans are national "spark" engineering products, which have the characteristics of excellent performance, high temperature resistance, high efficiency, less land occupation than centrifugal fans and convenient installation.
2.HTF fire-fighting fan has excellent high-temperature resistance: the fan test meets the requirements of GBJ45-82 fire-fighting standard, and an enterprise internal control guarantee system higher than this standard has been established, which can run continuously at 300℃ for more than 60 minutes and run continuously at 100℃ for 20 hours without damage, and is widely used in advanced civil buildings, ovens, underground garages, tunnels and other occasions.
3. The performance listed in the 3.HTF fire-fighting fan performance table is within the highest efficiency range, and it is divided into five performance points according to the air volume, and the performance table shall prevail when selecting. Qualified fire-fighting fans leave the factory under the rated air volume, and the total pressure error is less than 5%. The performance selection table is the performance in the standard state, regardless of the technical documents or order requirements.
