In demanding environments such as pharmaceutical workshops, electronic cleanrooms, biological laboratories, and precision testing rooms, stable airflow, precise airflow control, and pressure self-adaptation are crucial for ensuring environmental compliance. Venturi valves, as core airflow control components in HVAC and cleanroom ventilation systems, have become the mainstream choice for variable air volume (VAV) systems and FFU (Fan Filter Unit) systems due to their self-regulating structure, high-precision adjustment, and low pressure loss.

In high-end industries such as electronics and semiconductors, biomedicine, and precision manufacturing, cleanrooms are the "core sanctuary" for ensuring product quality. They need to maintain constant temperature and humidity, as well as extremely high air cleanliness, to prevent tiny dust particles and temperature and humidity fluctuations from interfering with precision production and experiments. However, what is little known is that this "pure land" comes at an extremely high energy cost: a medium-sized cleanroom often consumes dozens of times more energy than an office building of the same size, with ventilation and air handling accounting for over 60% of the energy consumption, becoming a double burden on enterprise operating costs and environmental pressure.

Modular cleanrooms, with their advantages of flexible assembly, rapid deployment, and relocation, are widely used in industries with strict cleanliness requirements, such as electronics, pharmaceuticals, biology, and food. Compared with traditional cleanrooms, while modular structures offer greater stability and convenience, the standardization of daily maintenance directly determines their ability to maintain cleanliness levels and their service life.
