How to build a cheap clean room?

Building a modular clean room is essential for many laboratories and production workshops, but many people think that its construction cost is too high. In fact, through reasonable planning and selection of materials, structures and installation methods, costs can be effectively reduced while meeting basic clean requirements. This article will elaborate on how to build a cheap but fully functional clean room from three aspects: cleanliness level, structural materials, and installation costs.

Cleanliness level controls cost

Cleanliness level is a key factor in determining the construction cost of A Clean Room. The higher the requirements of the clean room, the higher the cost of the required equipment and materials. Therefore, a reasonable choice of cleanliness level can effectively control the cost of the clean room.

1. High cleanliness level increases cost

For example, ISO 5 Clean rooms require extremely high air quality and need to be equipped with efficient air filtration systems (HEPA filters) and air handling equipment, which will greatly increase costs. Such clean rooms are usually used in Semiconductor production or high-end medical equipment manufacturing, and the construction cost may be more than twice that of ordinary clean rooms.

2. Medium cleanliness level is more cost-effective

ISO 7 or ISO 8 Clean rooms are usually suitable for food processing, general pharmaceutical production and other fields. The air quality requirements of this type of clean room are lower, the equipment and materials used are relatively simple, and the cost is about 50% to 60% of ISO 5. Choosing a medium cleanliness level can not only meet most needs, but also significantly reduce costs.

3. Regularly evaluate cleanliness requirements

When planning a project, the appropriate cleanliness level should be selected according to the actual operational needs. Avoid unnecessary over-design by regularly evaluating the cleanliness requirements of the production process or experiment. For example, if only basic experiments are conducted, ISO 9 can meet the needs, and its construction cost is about 20% of ISO 5.

Control the cost from the structural construction materials

The choice of structural materials has a great impact on the cost of the clean room. The use of different materials not only affects the stability of the clean room, but also directly affects the overall cost. Choosing the right material according to the needs can help save a lot of costs.

1. Soft curtain clean shed is the cheapest

Soft curtain clean shed is the lowest cost option, suitable for small-scale laboratories with limited budget. It mainly isolates air flow through plastic curtains or soft films to prevent pollutants from entering. The cost of building this structure is about half of that of hard wall clean shed, and the installation period is short. Although the clean effect is limited, it can fully meet the requirements for environments with low demand.

2. Hard wall clean shed is moderate

Hard wall clean shed is built with metal frame and smooth wall, with stable structure, suitable for most laboratory environments. Its construction cost is moderate, higher than soft curtain structure, but lower than purification board structure, suitable for most places with medium clean requirements. Its cost is about 1.5 times that of soft curtain structure, which can provide better air isolation effect and long-term use guarantee.

3. Cleanroom with purification board is more expensive

Cleanroom with purification board is usually built with special purification board (such as polyurethane or color steel plate). Although the cost is higher, its stability, durability and isolation effect are the strongest. For places that require long-term stability and high cleanliness requirements, cleanrooms with purification panels are the best choice. Compared with hard-wall cleanrooms, the cost of purification panel structures is usually 50% to 100% higher.

Control the cost from the installation cost aspect

The cost of the installation process is often overlooked, but in fact, a reasonable choice of installation method can also save a lot of costs. By simplifying the installation process or choosing an economical installation solution, the overall cost can be effectively reduced.

1. Choose modular design

The modular cleanroom with modular design can be installed quickly, reducing the construction period and labor costs. This design uses prefabricated components and standardized equipment, which can be quickly assembled on site. Compared with traditional custom designs, modular installation can reduce installation costs by 30% to 40%. For small projects with limited budgets, modular design is an ideal choice.

2. Self-installation saves labor costs

In some cases, if you have certain technical capabilities, you can choose to install the cleanroom yourself and reduce your reliance on outsourced installation services. Although this may increase certain time costs, in areas with high labor costs, self-installation can save a lot of expenses. For example, the outsourcing cost of a complex installation may be as high as 15% to 20% of the overall project cost.

3. Choose standardized equipment and systems

Choosing standardized equipment (such as ventilation systems, Air Filters, etc.) instead of customized equipment can significantly reduce the cost of equipment procurement and installation. Standardized equipment is not only low-priced, but also easy to maintain and replace. In many cases, the overall cost of standardized equipment can be 30% to 50% lower than customized equipment.

Through the above analysis, we can see that it is not impossible to build a cheap clean room. Through reasonable clean level selection, structural material matching and installation method optimization, the cost can be greatly reduced without affecting the use effect and long-term operation stability.
