What is a cleanroom?

The most accurate way of answering this question is by quoting the ISO standard definition of a cleanroom. This is the standard which all cleanrooms must conform to and the following explanation gives the defining parameters of a cleanroom.

A cleanroom is a "room within which the number concentration of airborne particles is controlled and classified, and which is designed, constructed and operated in a manner to control the introduction, generation and retention of particles inside the room".

Ref: BS EN ISO 14644-1:2015 Cleanrooms and associated controlled environments - Part 1: Classification of air cleanliness by particle concentration

Modular Cleanroom Design

A modular cleanroom is a freestanding structure which convert an existing facility into a classified clean environment. It is a fully scalable solution, as it can easily be extended or relocated to adapt to a change in demand. The modular nature of the design means a modular cleanroom can be made to any size - from just a few square meters, to hundreds of square meters. It can also be installed in and around existing machinery. They can withstand the high volume of airflow required to achieve ISO classified, ultra-clean environments.

Cleanroom Standards

The Cleanroom Standard ISO 14644-1:2015 details a range of cleanroom classes. The classes are defined by numbered cleanliness levels, based on airborne particle counts.

The class you require will depend on your process, industry guidelines or legislation.


Cleanroom Air Handling & HVAC

High humidity can affect a cleanroom as it could be a breeding ground for micro-organisms; whereas low humidity can cause static. However, this is in extremes. Typically air conditioning and humidity control are only needed for operator comfort or process control and are not a specific requirement of ISO 14664-1.
