If you arrive here for the first time, you should know that this article takes part in a series of design considerations for cleanroom HVAC calculations. Previous considerations you should have clear to proceed with the cleanroom air balance are the following:
There are a number of best practice guides and benchmarks for cleanroom air change rates (ACR). Many of which reference charts dating back as far as 20+ years. Most commonly referenced are ISO 146144-4 for hourly air changes and air velocity rates, and Federal Standard 209E for fan filter ceiling coverages.
Cleanroom fan filter coverage is an important consideration when designing and constructing a cleanroom. Fan filter coverage is largely determined by cleanroom air flow requirements. A room with faster air change rates requires more airflow, thus will also require additional fan filter units to achieve the desired air flow velocity and room air change rates.
We will certify its cleanrooms to guarantee “as built” compliance with cleanliness standards. What matters, though, is how the cleanroom performs in real world applications—in your application, with your personnel and processing equipment.
How to make sure your industrial cleanroom is built on-time, on-budget and meets your cleanroom classification needs.
In accordance with the ISO 14644 standards, ISO Class 7 cleanrooms represent a highly controlled environment that is engineered to maintain specific cleanliness values. The enclosed system encompasses ceiling-mounted fan filter units (FFUs) that generate a continuous supply of HEPA or ULPA-filtered air. In this article, we'll cover top-level considerations and standards for ISO 7 cleanroom design and construction. Additionally, we'll explore general principles for ISO 7 standards including particulate levels, ACH requirements, and equipment-based considerations among several unique applications.
ISO-7 cleanroom classification is a common medium level of the cleanroom classes. The ISO cleanroom standards are set by the International Organization for Standardization (https://www.iso.org/standards.html). They are a private international organization with a membership of 167 national standards bodies. The ISO cleanroom classification system used in the United States is primarily for pharmaceutical cleanrooms, medical device cleanrooms, biotech cleanrooms, life-science cleanrooms, and USP797/800 compounding cleanrooms. Europe and the rest of world uses the ISO cleanroom classification system for all industries except semiconductor.
Maintaining a compliant cleanroom is vitally important. CLIN, a leading manufacturer of cleaning and disinfection supplies, is committed to partnering with customers in various industries such as pharmaceutical manufacturing, biotechnology, and ATMP manufacturing.
I have to admit, I’ve also been confused about the cleaning protocols and procedures for a cleanroom environment. The basic techniques, I’ve got that down (but I’ll talk about that too); there’s a lot of products to clean with and rotating your cleaning agents. It’s confusing to say the least and the internet is vast and for something so important how do you trust the information (since you are reading this online – myself included!)? I’ll share my references and you can see where I’m getting this information on clean room protocol. I’ve found a source that not only knows what they’re talking about and have the proper credentials but also speaks on a practical level that makes sense to me. I’ll try to be as concise as possible in explaining this because you’ll see the basics don’t necessarily warrant an hour long discussion.
When you operate a cleanroom, it's imperative to maintain strict standards of cleanliness in the facility at all times. Whether you work in healthcare, biotechnology, pharmaceuticals, aerospace, or any other setting where cleanrooms are employed, a rigorous cleaning protocol is vital.
