Modular Clean Rooms


Through expert in-house knowledge and a number of dedicated partners, who allow us to guarantee a low level of internal pollutants, we provide a modular cleanroom design that can be sited externally but linked to your facility.

This gives an alternative option to the current cleanroom market offering of within an existing building taking up valuable internal space and sited where space is created not necessarily where it needs to be.

With 30 years’ experience in modular design we understand how to address your challenges. Perfect for when the requirement is for a limited timespan a single module can be upgraded or added to quickly and with one of our recent installations a pharmaceutical client is saving $1M per annum by being a process in-house with a modular cleanroom complex.

Used in the medical, biotech, pharmaceutical, manufacturing, technological and food and drink industries clean rooms are also instrumental in selected process manufacturing in the aerospace, military and other engineering.


Cleanrooms are controlled environments that prevent contamination from dust and airborne microbes. All our cleanrooms are supplied with the latest air filtration systems to ensure air is highly filtered and continually circulated to exclude pollutants and delivered to site ready-to-use and with complete installation. This includes full certification, electrics, heating, plumbing, and air conditioning, as well as temperature and humidity control. Our rooms can achieve temperatures between 60°C and +85°C, with humidity levels between 5% and 95% RH. Data logging equipment also comes as standard, providing traceability.

We offer cleanrooms with ISO classifications 5-8. Classifications are determined by the number of air changes required per hour in accordance with BS EN ISO 14644.

Classification Air Changes Per Hour
ISO Class 8 (Class 100,000) 5 – 48
ISO Class 7 (Class 10,000) 60 – 90
ISO Class 6 (Class 1,000) 150 – 240
ISO Class 5 (Class 100) 240 – 480


Cleanroom Solution Walkthrough 2019 | Dawsongroup temperature control solutions

Typically used in manufacturing or scientific research, Cleanrooms are controlled environments that prevent a process from contamination. This is in the form of dust and airborne microbes. The level of cleanliness is determined by the number of airborne particles larger than 0.5um, that are present per cubic metre of air. As well as this, the​ total number of complete air changes are needed per hour.
