### Ventilation fan box product introduction
The ventilation fan box is a ventilation equipment designed for industrial and commercial buildings. It has the following characteristics:
1. High-quality materials and structural strength: The impeller and shell of the ventilation fan box are made of high-quality galvanized steel plates, all molded, and riveted and biting mechanical connections are used to avoid welding deformation. The surface is clean and flat, ensuring the structural strength and durability of the box.
2. Modular design: The galvanized steel plate box of the fan box adopts a frame and box plate assembly design. The frame is stretched and formed by an advanced cold bending unit in one time. This design makes the surface clean and beautiful, corrosion-resistant, easy to disassemble, and can be installed on site.
3. Diversified applications: The ventilation fan box has many varieties and specifications, a wide range of air volume and air pressure, and is equipped with multi-directional air inlets and outlets. The unit can be installed in a ceiling-mounted or floor-standing manner, which is convenient for installation and engineering design.
4. Low noise and high efficiency: The ventilation fan box has the characteristics of low noise, low vibration, large air volume and small size. It adopts a fully metal detachable frame and an internal heat-insulating sound-absorbing board, which can be disassembled and assembled on site and is flexible to place.
### Fire fan box product introduction
The fire fan box is a high-performance equipment specially used for fire smoke exhaust. It has the following characteristics:
1. High temperature resistant structure: The fire fan box adopts a high temperature resistant structural plate, and the motor and transmission components are all placed at the outer end of the fan box. It can discharge high-temperature smoke above 280℃ for more than 100 minutes.
2. High efficiency smoke exhaust performance: The fire fan box can run continuously for more than 60 minutes at a high temperature of 300℃ and for 20 hours/time at a temperature of 100℃ without damage. It is widely used in high-end civil buildings, ovens, underground garages, tunnels and other places.
3. Compact structure and low noise design: The fire fan box adopts a combined structure, which is easy to disassemble and assemble on site, and has the characteristics of compact structure and small space occupation. At the same time, the low-noise design is adopted, and the noise level during operation is reduced by optimizing the fan impeller and box structure.
4. One machine for two purposes: The fire fan box is divided into two types: A and B. The motor is installed outside the box for type A. After high temperature resistance test, it can run continuously for more than 40 minutes when the smoke temperature is greater than 280℃, achieving the purpose of fire smoke exhaust. After being equipped with a dual-speed motor, it can be used for ventilation at low speed and fire smoke exhaust at high speed, which is a dual-purpose machine.
The above introduction summarizes the main features and application scenarios of ventilation fan boxes and fire fan boxes.
