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: core fan and axial fan. Centrifugal fan: the air current moves along the diameter 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 complies with the requirements of the fire code standard, and establishes an enterprise internal control guarantee system higher than this standard. It can continuously run for more than 60 minutes at a high temperature of 300 ° C and a continuous 20 hours at a temperature of 100 ° C. 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, and the performance table shall prevail.
Our exhaust fan is not only resistant to high temperature, but also small in size, light in weight and simple in construction. 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.
