In today's precision-driven industries, the environment where products are made is as critical as the manufacturing process itself. Whether in pharmaceuticals, biotechnology, microelectronics, or aerospace, the control of contamination is paramount. This is where the science and engineering of cleanrooms design come into play.
A well-executed cleanroom design is the foundation for achieving and maintaining the stringent levels of air purity required for sensitive operations. It’s not merely about building four clean walls; it’s an integrated system that balances airflow, pressure, temperature, and humidity to create a perfectly controlled microenvironment.
For engineers, facility managers, and decision-makers, understanding the nuances of cleanrooms design is the first step toward a successful project that ensures product quality, compliance, and operational efficiency.

The primary goal of any cleanroom design is to prevent particulate and microbial contamination. A single speck of dust or a lone microorganism can compromise an entire batch of semiconductors, render medical implants unsafe, or invalidate critical research data.
Poor cleanroom design leads to inconsistent air patterns, dead zones where contaminants can accumulate, and difficulty in maintaining stable temperature and humidity. This results in frequent failures during regulatory audits, costly production downtime, and an increased risk of product recalls.
Investing in professional cleanroom design from the outset mitigates these risks. It ensures the facility is built to meet exact classification standards (like ISO 14644-1) reliably and cost-effectively over its entire lifecycle.
There is no one-size-fits-all solution. The optimal cleanroom design depends heavily on the specific processes it will house. Here are two fundamental airflow designs:
Turbulent Flow Cleanrooms Design
This design is typically used for lower cleanliness classifications (e.g., ISO Class 7 and 8). Conditioned air is supplied through HEPA or ULPA filters located in the ceiling and returned through vents located low on the walls.
Best For: Areas where processes are not ultra-sensitive, such as some packaging areas, electronics assembly, or as an anteroom to a higher-class cleanroom.
In this design, air moves in a single pass, in one direction, with a constant velocity. It typically comes in two forms: Vertical Laminar Flow and Horizontal Laminar Flow. This is used for the most stringent classifications (e.g., ISO Class 1 to 5).
Best For: Critical applications like semiconductor wafer manufacturing, sterile fill-finish operations in pharmaceuticals, and advanced biomedical research.
A robust cleanroom design integrates several core components. At TAI JIE ER, our engineering approach focuses on harmonizing these elements.
Air Filtration and Handling Units (AHUs)
The heart of the cleanroom design is the AHU. It conditions the air—heating, cooling, humidifying, or dehumidifying—and pushes it through a series of pre-filters and final HEPA/ULPA filters to achieve the required cleanliness level.
Pressure Differential Control
Cleanrooms are maintained at a positive or negative pressure relative to adjacent spaces. This prevents unfiltered air from flowing into the clean environment. A sophisticated cleanroom design includes automated controls to maintain these pressure cascades.
Materials of Construction
Walls, ceilings, and floors must be non-shedding, smooth, and easy to clean. Common materials include modular insulated metal panels, glossy epoxy paints, and seamless vinyl or resin flooring. The choice is a critical part of the custom cleanroom design process.
Lighting and Services
Sealed, recessed LED lighting is standard. The cleanroom design must also meticulously plan for the integration of utilities like clean gases, deionized water, and data connections without creating contamination leak paths.
At TAI JIE ER, we believe that every client’s needs are unique. We don’t just sell cleanrooms; we engineer solutions. Our process for a custom cleanroom design is collaborative and thorough.
We begin with a deep-dive consultation to understand your process flows, regulatory requirements, and budgetary constraints. Our team of experts then develops a comprehensive cleanroom design that is both high-performing and cost-effective.
We specialize in creating custom cleanroom design solutions that fit into existing buildings or new greenfield projects. Our expertise ensures that the final build is compliant, efficient, and tailored for your specific operational workflow, maximizing your return on investment.

Before you begin, ask these critical questions:
What is your target ISO Classification? This is the most fundamental driver of cost and complexity in your cleanroom design.
What are your operational requirements? Consider the number of personnel, equipment heat load, and process-generated contaminants.
What is your budget and timeline? Being upfront about these constraints allows your cleanroom design partner, like TAI JIE ER, to propose realistic and achievable solutions.
What are the regulatory hurdles? Different industries (FDA, EMA, cGMP) have different guidelines that must be baked into the cleanroom design from day one.
The cost of a cleanroom design and build project is highly variable. Key factors include:
ISO Classification: The cleaner the room, the higher the cost due to more advanced filtration and airflow requirements.
Size and Scale: Larger areas require more materials, larger AHUs, and more complex control systems.
Customization Level: A standard modular cleanroom design is less expensive than a custom cleanroom design with specialized utilities, process interfaces, and architectural finishes.
Site Conditions: Retrofitting a cleanroom into an existing building often presents more challenges and costs than a new construction.
Partnering with an experienced firm like TAI JIE ER helps you navigate these cost factors. We provide transparent pricing and value-engineered options to ensure your project stays on budget without compromising on quality or performance.
Q1: How long does a typical cleanroom design and construction project take?
A1: The timeline varies significantly based on the project's scale and complexity. A simple modular cleanroom can be operational in a few weeks, while a large, highly complex custom cleanroom design for a pharmaceutical facility can take 6 to 18 months from initial design to final validation. TAI JIE ER provides detailed project timelines after the initial consultation.
Q2: Can you design a cleanroom within an existing building?
A2: Absolutely. A significant part of our work at TAI JIE ER involves retrofitting and integrating high-performance cleanroom design into existing facilities. This requires careful planning around structural limitations, existing utility services, and minimizing disruption to ongoing operations.
Q3: What is the difference between a modular and a stick-built cleanroom design?
A3: A modular cleanroom design uses pre-engineered panels and components, offering faster installation, flexibility for future expansion, and often lower cost. A stick-built (or built-in-place) cleanroom design is constructed like a traditional building, which can be more durable and seamlessly integrated into a structure but is typically more time-consuming and less flexible to modify.
Q4: How critical is the validation process after the cleanroom is built?
A4: Validation is not just critical; it is mandatory. It is the formal process of testing and documenting that the cleanroom design and construction meet all specified performance criteria, including particle counts, airflow velocity, pressure differentials, and recovery time. This certification is required for regulatory compliance.
Q5: Why should I choose TAI JIE ER for my next cleanroom design project?
A5: TAI JIE ER brings a wealth of international experience and a client-centric approach to every project. We are not just contractors; we are your partners in contamination control.
