AK-WAVE Modular Softwall Cleanroom

A softwall cleanroom refers to a modularcleanroompanel using soft wall panel as partition walls.flexible, lightweight materials for the walls. These walls can be easily moved or adjusted to accommodate different production needs or space configurations. Softwall cleanrooms are typically constructed with a metal frame and lightweight PVC wallpanels. This type of cleanroom offers high flexibility, good cleanability, and is widely used in various fields such as electronics manufacturing(electronic cleanroom), pharmaceutical production(pharmacy cleanrooms), and laboratories(laboratory cleanroom). It also provides a cost-effective solution.

Hardwall cleanrooms and softwall cleanrooms each have their own advantages. Which one is better depends on the specific requirements and environment. Hardwall cleanrooms usually have higher sealing and better isolation performance, and can better control indoor environmental parameters such as temperature, humidity and air cleanliness. The hardwall cleanroom has a sturdy structure and can maintain excellent performance for a long time. It is suitable for application scenarios with high requirements for environmental control, such as semiconductor manufacturing and pharmaceutical production. The softwall cleanroom has higher flexibility and mobility, can be quickly built and disassembled as needed, suitable for temporary or short-term projects. The cost of softwall cleanrooms is relatively low, easy to transport and store, and suitable for scenarios where environmental control requirements are not particularly high, such as laboratories(laboratory cleanroom) and medical examinations （medical cleanroom）. The design and construction of softwall cleanrooms are relatively simple and can quickly adapt to different usage requirements.

In addition to providing basic environmental control, the hard-wall clean room can also achieve more comprehensive environmental control and protection through a variety of measures. In terms of environmental control, the hard-wall clean room ensures that the cleanliness, temperature and humidity of the indoor airflow meet specific standards through efficient air filtration and purification and air conditioning systems; in terms of safety protection, the design of the hard-wall clean room includes fire safety measures, and the enclosure materials used are flame-retardant/non-combustible materials that meet fire protection requirements. In addition, the hard-wall clean roomcanalsobe equipped with fire hydrants, automatic sprinklers, smoke sensors and other fire protection facilities to deal with potential fire risks; in terms of lighting and alarm systems, in addition to daily lighting systems, hard-wall clean rooms also include emergency lighting and evacuation instructions for personnel evacuation, and fire detectors are set up in key areas to achieve early detection and early alarm to improve safety. Hard-wall clean rooms include not only basic air filtration and temperature and humidity control, but also fire safety, emergency lighting and alarm systems. These facilities together constitute an efficient and safe working environment.

In addition to air cleanliness control, softwall cleanroomcan also providecontrol on temperature, humidity,  differential pressure and noise. In terms of environmental control, the soft wall clean room, through high efficiency air filters and air conditioning system,ensures that the cleanliness, temperature and humidityinside canmeet specific standards, and maintain the stability and quality of the products. In terms of pressure control, the soft wall clean room can maintain the necessary positive pressure to prevent the influence of external pollution on the clean area. In terms of noise control, soft wall clean rooms help reduce indoor noise through design and material selection, providing a quiet working environment.

Positive pressure clean room refers to the statewhere air pressure inside the clean room is greater than the ambient air pressure. In this state, the air supply volume of the clean room is adjusted‌to make it greater than the sum of return air volume and exhaust air volume, thus forming a positive pressure difference‌to prevent the infiltration ofpolluted air fromsurrounding clean space at lower clean class, unclean space or outdoorenvironment, which willaffect the cleanliness of the clean room. Themajorsignificance of maintaining positive pressure is to prevent the entry of external pollutants, to ensure the purity of the production environment, especially for thecriticalproduction process that needs to be highly clean. Positive pressure clean room is widely used in pharmaceutical, electronics and other industries.

Negative pressure clean room refers to the statewhere air pressure in the clean room is lower than the ambient air pressure. The main purpose of the design of the negative pressure clean room is to prevent the leakage of contaminated indoor air to the outdoor thereby reducing the risk of cross-contamination and infection. Negative pressure clean rooms are widely used in hospital wards, operating rooms, laboratories and other fields, among which negative pressure hospital wards are especially suitable for rescuing patients with respiratory infectious diseases. The design of ventilation system makes the air pressure inside the ward lower than that outside the ward,‌ensuring the inflow of fresh air. The air contaminated by the patient is specially treated by the exhaust pipe and then sent to the designated place to protect the medical staff and the surrounding environment from infection orcontamination.

The main difference between apositivepressure and a negative pressure clean room is the direction of air flow and the application scenario.‌

The positive pressure clean room workshopfocuses on the protection of products from external environmental pollution, making itsuitable for industries with high cleanliness requirements, such as‌microelectronics, pharmaceutical, etc., which is conducive to maintaining product quality and production efficiency.

Negative pressure clean roomis dedicated tocontrolling the spread of internal pollutants and protecting the health andsecurityofoperators, widely used in industries with strict requirements for waste gas, harmful gases and particulate matter generated in the production process,‌such as chemical industry,‌pharmaceutical and so on.
