Determine Your Cleanroom Classifications
A cleanroom is like a fine-tuned Formula 1 racing car. Built correctly and meeting the regulations, it can perform to the highest standards. If not and you don’t have a design in place, don’t understand what you’re trying to achieve and don’t use a quality cleanroom provider, it’s going to be the equivalent of a car with a failing engine.
As part of the design, there are a number of different things you need to consider within your cleanroom design. Cleanliness levels, airflow, environmental pressure, it’s all critical. Let’s look at what specifically you need to think about for your cleanroom design.
1 – Cleanroom Cleanliness Requirements
An enclosed space that keeps cleanliness within strict and predetermined limits, there are various different levels of cleanliness a cleanroom can adhere to. The standards of different cleanliness classifications are provided by the IEST (Institute of Environmental Science & Technology) Standard under ISO 14644-2015.
Referring to the concentration of airborne particles, the classification that you are aiming for has a significant impact on how your cleanroom is designed and how much energy is used within its operation. Cleanroom facilities must maintain a maximum concentration of 10 particles of 0.1 micrometers or larger per cubic meter of air to reach the highest cleanliness standard. Such a level of performance is usually required in semi-conductor or micro-electronics facilities where the smallest particle contamination can have dire consequences on production.

Understanding what level of cleanliness is required for the type of process housed within your premises will have the biggest impact on the project’s leadtime and costs. Understandably, the cleaner the cleanroom, the more technically advanced the facility will be.
Beside semi-conductor manufacturing, ISO Class 1 cleanroom (the highest cleanliness standard) are also widely used for production of optical devices like lenses, lasers and fiber optics. Beyond ISO Class 5, the cleanliness levels are sufficient to ensure a total protection against micro-organisms. Therefore, industries like pharmaceutical or biotechnologies can thrive within such environments.
It’s also important to understand that when designing cleanrooms, connecting spaces can’t be more than 2 orders of classification apart, so make sure that the internal workflow within the cleanroom sticks to these parameters.
