Fire protection features: good high temperature resistance and high efficiency (Draught Fan) is a widely used fan product, and its ultra-high performance has been widely recognized by users. However, when choosing to purchase a fire smoke exhaust fan, it is necessary to understand some product information. How much do you know specifically about this information?
        Firefighting characteristics: Good high temperature resistance and high efficiency. Partial improvements are needed in the manufacturing process and configuration, specifically manifested in:
        1. In terms of production technology: The surface of the fire exhaust fan should be smooth and flat, without processing defects or scratches, and the coating should be uniform. Low noise axial flow fan is an indispensable key equipment in the kitchen. It is recommended not to install it in the ceiling as much as possible, but to install it in places such as computer rooms, roofs, or exterior walls that are easy to maintain. The welding joints of the fan casing should be full and free of defects such as slag inclusion, bubbles, and virtual welding, and the layout should be firm.
        2. In terms of configuration: The casing of the fire exhaust fan has been specially designed to produce significant low vortex noise. Obtain higher fan pressure in low-speed environments. Another thing we need to know is that the impeller of the fire smoke exhaust fan (referring to the disc with moving blades) rotates normally, runs smoothly, has no abnormal vibration or noise, and the fastening connection is not loose.    
        1. It should be vertical, horizontal or suspended ceiling type, and the air outlet and inlet/outlet direction should be indicated.    
        2. What is the residual pressure at the export.    
        3. The number of draft fans inside the unit. The 3C smoke exhaust fan is a mechanical device that can quickly remove odors, high temperatures, and cooking fumes generated during food processing in the kitchen. The machine is characterized by good high-temperature resistance and high efficiency.    
        4. To adjust the control box for variable air volume, a separate order is required.    
        5. Please indicate whether the filter is pulled up or down, left or right.    
        6. Is it a four row heat exchanger or a six row heat exchanger? The fresh air is usually six row pipes. The smoke exhaust fan box should be able to operate normally for a long time under the condition that the medium temperature is not higher than 85 ℃.
