Before initiating a cleanroom HVAC design, HVAC system designers must possess a profound understanding of sterile product characteristics, process sequences, and equipment operations. Corresponding measures must be integrated into the HVAC design to optimize critical components such as airflow patterns, airflow visualization, and filtration efficiency in accordance with GMP compliance and sterile manufacturing requirements. This…

With over a decade of experience in cleanroom engineering, I consider ISO 14644-4:2022 one of the most practical tools in my daily arsenal. Unlike ISO 14644-1, which focuses on classification, Part 4 serves as a “hands-on manual.” It outlines the entire lifecycle of a cleanroom—from the first blueprint to formal commissioning. Its core objective is…

So, your clean room construction is complete—but is it actually compliant? As a clean room engineer with over 15 years of inspection experience, I often tell my clients: a clean-looking room with running equipment is not enough. To officially hand over a project, you must strictly follow the GB 50687-2011 code (or equivalent ISO 14644…

The control of temperature and humidity in a cleanroom is essential for maintaining product stability, ensuring GMP compliance, and providing a comfortable working environment for personnel. I. General Requirements for Temperature and Relative Humidity The primary principle for setting temperature and relative humidity is to balance pharmaceutical production process standards with operator comfort. II. Special…

Having spent years in cleanroom field management and purification O&M (Operations & Maintenance), I am frequently asked a very practical question: For daily environment and equipment surface disinfection, is direct spraying more efficient, or is manual wiping more reliable? Based on field experience and industry regulatory requirements, my answer is straightforward: In a cleanroom environment,…

Unlike steam sterilization where the D-value remains relatively stable, the D-value during Vaporized Hydrogen Peroxide (VHP) sterilization fluctuates significantly based on concentration, humidity, and condensation levels. Consequently, a unified calculation like F0 is not applicable. Based on USP <1229.11> “Vapor-Phase Sterilization” and relevant research, this article explores the definition and the four critical phases of…

Over my years in the cleanroom industry, I’ve found that flooring selection is often the most debated—and mistake-prone—aspect for our clients. Choosing the right floor isn’t just about aesthetics; it directly impacts your ability to meet cleanliness standards, eases daily maintenance, and extends the facility’s lifespan. The wrong choice can lead to dust accumulation, cracking,…

After a decade in the food cleanroom engineering industry, I’ve noticed a recurring pattern: most enterprises “fall into the trap” when it comes to facility and equipment selection. Whether it’s failing to meet regulatory audit requirements or poor management leading to costly retrofits, these mistakes drain both time and capital. In a food cleanroom, the…

I’m Zhou, in charge of Boben’s Middle East operations. For eight years, I’ve been on the front lines exporting cleanroom equipment to Saudi Arabia, the UAE, Egypt, and across the Gulf. The Middle East pharmaceutical sector is exploding. Last year alone, we secured Modular Weighing Room orders for 27 local pharma plants. But I’ve also…

“Class 10,000 cleanliness,” simply put, refers to an environment where the number of dust particles with a diameter of 0.5 microns or larger does not exceed 10,000 per cubic foot of air. When converted to cubic meters, this corresponds to a limit of 352,000 particles. The term “Class 10,000” originates from the U.S. Federal Standard…

When you need to upgrade the cleanliness of a specific production line, building a full-scale, permanent cleanroom is often overkill—both in terms of time and budget. This is where the Modular Clean Booth (often called a “room-within-a-room”) comes into play. It’s the industry’s favorite “shortcut” to achieving high-purity environments exactly where they’re needed, without the…

When many clients first reach out to us, they usually have a similar concern:It’s not that they don’t need a cleanroom — they’re just wondering if there’s a more flexible, less heavy approach. Traditional cleanrooms are reliable, no doubt. But the long construction time and high upfront investment can feel excessive, especially for temporary projects…
