What is a cleanroom?

A cleanroom as defined by ISO standards 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”. Here in the blog, we are discussing about some Cleanroom Requirements.

Cleanrooms are an essential part of any manufacturing process where particulate contamination can affect the quality of goods produced. Specific clean room classifications and ISO class code descriptions provide the required protective guidelines and secure environments through controlled air filtration.

In addition to the air filtration the clean room classifications require that positive pressure is continuously maintained while the cleanroom is in use. This prevents any contaminated air from flowing back within the clean air environment.

Cleanroom ISO Class Code Descriptions

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.

Defining the correct cleanroom standards for your new product or business requires consideration of many aspects. These can include process requirements, cost, design, performance and construction. Our team work with you to understand your needs and all applicable cleanroom requirements in industry.

ISO Class 1 – The “cleanest” cleanroom is ISO 1, used in industries such as life sciences and electronics that require nanotechnology or ultra-fine particulate processing. The recommended air changes per hour for an ISO class 1 clean room is 500-750, and the ceiling coverage should be 80–100%.

ISO Class 2 – 500-750 air changes per hour, with a ceiling coverage of 80-100%.
ISO Class 3 – 500-750 air changes per hour, with a ceiling coverage of 60-100%.
ISO Class 4 – 400-750 air changes per hour, with a ceiling coverage of 50-90%.
ISO Class 5 – 240-600 air changes per hour, with a ceiling coverage of 35-70%.
ISO Class 6 – 150-240 air changes per hour, with a ceiling coverage of 25-40%.
ISO Class 7 – 60-150 air changes per hour, with a ceiling coverage of 15-25%.
ISO Class 8 – 5-60 air changes per hour, with a ceiling coverage of 5-15%.

Our team can design and install your cleanroom on site with minimal disruption.
