What is Cleanroom Construction? Definition, ISO Grades & Core Standards Explained

In the construction and engineering sector, a Cleanroom is far more than just a “clean room.” It is a specialized, enclosed environment where environmental parameters—such as airborne particulates, temperature, humidity, air pressure, and microbial levels—are strictly controlled.

It is a complex engineering system integrating architectural structure, ventilation, filtration technology, and intelligent control. Its core objective is to create a stable environment that prevents contaminants from compromising product quality or scientific research.

With 14 years of deep expertise, boben Modular Cleanroom Manufacturers specializes in flexible, high-efficiency solutions, making us the preferred partner for architectural cleanroom projects worldwide.

1.Core Design Principles of a Cleanroom

The heart of cleanroom design is “Contamination Control.” This is achieved through three critical systems:

A. Air Purification System

This is the “heart” of the cleanroom. It uses a three-stage filtration system (Pre-filter + Medium filter + HEPA/ULPA filter) to capture dust and microorganisms.

• boben Modular Cleanroom Suppliers utilize H13-H14 grade HEPA filters with an efficiency of 99.99% or higher, ensuring the air quality meets ISO Classes 1 through 9 tailored to your needs.

B. Airflow Organization

Depending on the application, we employ Vertical Laminar Flow, Horizontal Laminar Flow, or Turbulent Flow.

• The Goal: Uniform air supply and rapid return air speeds eliminate “dead zones” (vortices), ensuring contaminants are flushed out immediately rather than accumulating.

C. Differential Pressure & Sealing

• Pressure Control: Cleanrooms maintain a specific pressure difference (positive or negative) relative to adjacent areas to prevent unfiltered air from infiltrating.
• Sealing: We use high-performance materials, such as hermetic doors, seamless flooring, and dust-free ceiling systems, to eliminate any potential leakage paths.
• Environmental Control: Integrated systems precisely manage temperature (±1℃), humidity (±5% RH), static electricity, and noise (≤60dB).

2.Cleanrooms in Construction: Key Characteristics & Benefits

Precise ISO Classification
Cleanrooms are graded by cleanliness according to ISO 14644 standards, ranging from ISO Class 1 (cleanest) to ISO Class 9.

• Chip Manufacturing: Requires ISO 1-3.
• Pharmaceuticals: Typically ISO 5-7.
• Food Processing: Generally ISO 8-9.

Modular Design: Flexible & Efficient

Traditional cleanroom construction involves long lead times and difficult renovations. In contrast, boben Modular Cleanroom Manufacturers champion the Modular Cleanroom approach.

• Speed: Uses prefabricated components for on-site assembly, reducing construction time by over 50%.
• Flexibility: Can be easily disassembled, relocated, or expanded as your production capacity grows, significantly lowering renovation costs.

Energy Efficiency & Sustainability

By optimizing fan selection, using low-resistance filters, and integrating heat recovery systems, our modular cleanrooms reduce energy consumption by 20%-30% compared to traditional builds. We use low-VOC, easy-to-clean materials aligned with global green building trends.

Stability & Maintenance

Standardized components make maintenance and part replacement effortless. Paired with intelligent monitoring systems, users can track cleanliness, pressure, and humidity in real-time, with automatic alarms for any abnormalities.

3.Typical Application Scenarios

Cleanrooms are now essential infrastructure across various industries:

• Electronics & Semiconductors: Chip manufacturing and circuit assembly require ISO 1-5 environments to prevent dust from causing short circuits or defects.
• Bio-Pharmaceuticals: Vaccine R&D and sterile preparations require ISO 5-7 environments that strictly adhere to GMP and FDA standards to prevent microbial contamination.
• Food & Beverage: Aseptic filling and supplement production require ISO 8-9 standards to ensure food safety and hygiene.
• Scientific Research: Microbiology labs, gene sequencing, and nanotechnology centers rely on stable environments for experimental accuracy.
• Other Fields: Aerospace precision parts, medical device manufacturing, and cosmetics.
