The DN3000 Jinbin large-diameter air damper has been completed in production
The large-diameterair damper of DN3000 is a key control component in large-scale ventilation and air treatment systems（pneumatic damper valve）. It is mainly applied in scenarios with large Spaces or high air volume demands such as industrial plants, subway tunnels, airport terminals, large commercial complexes, and thermal power plants. Its core functions revolve around "precise air control, ensuring system stability, and enhancing safety and energy efficiency". It can be specifically divided into four aspects:
A. Precise adjustment of air volume and air pressure
In large Spaces, the ventilation requirements in different areas vary significantly (for instance, the production area in an industrial workshop needs high air volume for heat dissipation, while the storage area requires low air volume for air exchange). The DN3000 air valve can precisely control the air flow and pressure through the pipeline by adjusting the blade opening, avoiding local excessive or insufficient air flow, ensuring that the ventilation parameters in each area meet the design standards, and at the same time reducing the noise and energy consumption caused by air flow imbalance in the system.
B. System Airflow truncation and zone control
When large ventilation systems need maintenance, are shut down in different zones or switch operation modes (such as when the air conditioning system switches between winter and summer modes), the DN3000 butterfly damper valve can be completely closed to "cut off and isolate" the airflow in specific pipelines or areas, preventing untreated air from flowing and affecting the environment, while ensuring the safety of maintenance personnel.
C. Safety Protection and Emergency Response
In scenarios with risks of fire and harmful gas leakage (such as underground garages and chemical plants), DN3000 air damper valve are often linked with the fire protection system: they automatically close the air dampers in non-smoke exhaust areas during a fire to prevent the spread of fire and smoke. When harmful gases leak, close the air valve in the contaminated area and open the exhaust channel to quickly discharge the harmful gases, reduce safety risks, and comply with building fire protection and industrial safety regulations.
D. Enhance the operational efficiency of the system
If large ventilation systems operate at full capacity for a long time, their energy consumption will be extremely high. The DN3000 air valve can dynamically adjust the air volume according to actual needs (such as the number of personnel and production load), avoiding energy waste. Meanwhile, its large-diameter design is suitable for high-volume ducts, reducing the resistance loss of airflow at the valve body, ensuring the operational efficiency of the entire ventilation system, and lowering the operating load and maintenance costs of the fan.
