Static pressure box, also known as static pressure box, is a device commonly used in air conditioning, ventilation, and air purification systems to regulate air volume and pressure, ensuring the normal operation of the system. It can be designed and built according to different system application requirements to adapt to different system requirements. By controlling the air volume and pressure, the normal operation of the system can be ensured, effectively ensuring the operational efficiency of the air conditioning system. The structure is simple, easy to install and maintain, which effectively reduces the maintenance cost and workload of the system.
