SEF series fire high temperature exhaust fan can be used for fire exhaust of various buildings. It can also be used for various buildings, air defense projects, underground railways, mines, tunnels and other exhaust and exhaust. The series of fire exhaust fans is designed and developed by Texas Aike Air Conditioning Equipment Co., Ltd. in accordance with the requirements of fire protection specifications for civil buildings, combined with the development of similar products at home and abroad. The inspection was passed by the National Quality Supervision and Inspection Center for Fixed Fire Extinguishing and Refractory Components.
SEF series fire high temperature exhaust fan has high temperature resistance
The fan is designed with a special motor cooling system. This series of high-temperature fire-fighting fans adopts motor cooling and main air flow dual channel mixed and discharged at the fan impeller inlet, which can not only cool the motor, but also make the heated gas flow away from the main air channel. , to improve the wind outside the environment. When the main air medium temperature is 280°C, it can be continuously operated for more than 30 minutes. Long-term continuous operation at ≤150°C.
SEF series high temperature smoke exhaust fan has the characteristics of small size and light weight.
SEF series fire high temperature exhaust fan is an axial flow fire exhaust fan, which accounts for less than two thirds of the space and less than half of the weight compared with the same volume of centrifugal fan.
SEF series fire high temperature exhaust fan structure is simple
The fan consists of five main components: 1 impeller 2 motor 3 internal circulation air cooling system 4 guide vanes, inner cylinder 5 outer cylinder. Simple structure, easy disassembly and maintenance. The structural design uses three-dimensional twisted vanes and leading vanes to allow the gas flow to conform to the space flow requirements.
SEF series high temperature smoke exhaust fan installation is more convenient
The fan can be installed horizontally and vertically according to the construction requirements. Three-phase power supply 380V, 50HZ

Ordering instructions
When ordering, please specify the axial fan number, speed, air volume, wind pressure, outlet angle and direction of rotation, as well as motor model, power, speed and so on.
The most important factors are volume and pressure.
To make the proper fan selection, you must consider the following system conditions the fan will be subjected to:
1. What is the required airflow?
This is rated in cubic feet of air per minute (CFM) or, in metric equivalent, it is rated in cubic meters of air per hour (M³/Hr).
2. What is the static pressure through the complete system?
This is rated in static pressure water gauge (SP) or, in metric equivalent, it is rated in Pascal's (Pa).
3. What is the ambient air temperature outside the fan?
4. What will be the airflow conditions through the fan?
- Clean or dirty (contaminated) air?Dry or wet (moisture laden) air?Temperature of air?
5. What is the altitude the fan will be operating in?
6. Will the air stream, inside the fan, contain anything that could be explosive or flammable?
7. Will the general location the fan will be operating in contain any type of explosive or flammable material or liquid?
Customized
When the exiting machine number, rotation, the wind angle and transmission mode can not meet the needs of users, we can design according to the fan similar theory and the user's specific parameters requirements.
