Application and performance characteristics of fire exhaust fan
The exhaust fan is widely used in industry and households. Let us introduce the functions and characteristics of the exhaust fan. At present, the exhaust fan can be divided into two types: the core fan and the axial flow fan. The centrifugal fan: the airflow moves along the diameter of the fan impeller; the axial flow fan: the airflow moves along the axial direction of the fan impeller. The centrifugal fan has a large total pressure and the motor is isolated from high-temperature soot gas. Not easily damaged. Axial flow fans are small. Generally, high-temperature oil fume gas passes through the motor and is easily damaged. Therefore, centrifugal fans are generally recommended for kitchens.
Features of the exhaust fan:
1. Fire-fighting high-temperature smoke exhaust fan has the characteristics of excellent performance, good high-temperature resistance, high efficiency, less land occupation than centrifugal fans, and easy installation.
2. The fire fan has excellent high temperature resistance performance: The fan test meets the requirements of the fire code standard, and an enterprise internal control guarantee system higher than this standard is established. It can run continuously for more than 60 minutes at a high temperature of 300 ° C and 20 hours at a temperature of 100 Without damage, it is widely used in high-grade civil buildings, ovens, underground garages, tunnels and other occasions.
3. The performance listed in the performance table of the fire fan is the performance within the highest efficiency range. It is divided into five performance points according to the air volume. When selecting, the performance table shall prevail.
Our company's exhaust fan is not only resistant to high temperature, but also has small size, light weight and simple structure. The fan is designed with a special motor cooling system. Its light weight makes it occupy less two-thirds of the space and reduce the weight by more than half.
