In modern buildings and industrial environments, the efficiency of the ventilation system is essential to maintain good air quality and comfortable working conditions. Among the many ventilation solutions, Negative Pressure Flexible Duct (NPFD) is popular for its flexibility and efficiency. In this article, we will focus on Negative Pressure Flexible Ducts made of Polyvinyl Chloride (PVC), in particular their antistatic properties and the influence of the ring spacing principle on the effectiveness of negative pressure.






1. The basic principle of negative pressure flexible piping




Negative pressure flexible ducting refers to the use of negative pressure to direct air from one area to another through a specific ventilation system design. The advantage of this design is the ability to effectively control air flow and reduce the spread of particles and pollutants. The formation of negative pressure relies heavily on the use of fans in conjunction with the material and structural design of the ducting to ensure smooth air flow during the ventilation process.








2. Advantages of PVC material




The use of polyvinyl chloride (PVC) for negative pressure flexible ducting has several advantages:
- Lightweight: PVC material is relatively lightweight and can be flexibly arranged in a variety of environments for easy installation and maintenance.
- Corrosion resistance: PVC has excellent chemical resistance, suitable for use in a variety of industrial environments, able to withstand the effects of the cold climate in the north and the humid climate in the south.
- Anti-static properties: anti-static PVC material can effectively reduce the generation of static electricity, thereby reducing the adhesion of dust and fine particles, further improving the efficiency of the ventilation system.








3. The influence of the principle of steel ring spacing on the effect of negative pressure




The spacing of steel rings is an important factor when designing negative pressure flexible ducts. The role of the steel ring is to maintain the shape and structure of the pipe to ensure that the pipe will not collapse under negative pressure. The design of their spacing directly affects the stability of negative pressure and the efficiency of air flow.


- Smaller spacing: Smaller spacing of steel rings can effectively enhance the rigidity of the pipe and reduce the deformation under negative pressure, thus maintaining the stability of air flow.
- Larger spacing: Although the weight of the duct can be reduced, it may lead to deformation under high negative pressure conditions, affecting the overall ventilation effect.


By reasonably designing the spacing of the steel rings, the best negative pressure effect can be realized during the use of the duct to ensure the continuity and stability of air flow.








4. Application Examples of Negative Pressure Flexible Ducting




Negative pressure flexible ducts are widely used in many industries and fields, the following are some specific application examples:
- Medical industry: In operating rooms, isolation wards and other environments, negative pressure systems can effectively prevent the spread of airborne pathogens and protect the safety of medical staff and patients.
- Industrial manufacturing: in chemical plants and pharmaceutical factories and other places, the use of negative pressure flexible piping can effectively control the leakage of chemical gases and dust, to ensure the safety of the working environment.
- Food Processing: In food workshops, negative pressure systems can maintain a high standard of hygiene and prevent contaminants from entering the production area, ensuring food safety.
- Construction: In construction sites, negative pressure ventilation can effectively remove dust and harmful gases, improving the comfort and safety of workers at work.
