But what is a cleanroom, and why are they so critical in so many sectors?

A cleanroom is defined as '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'. Most controlled environments protect the production of products like electronic devices, pharmaceuticals, and medical equipment, and cleanrooms are classified into different classes depending on the number of particles allowed in the air per cubic metre. They also control variables like temperature, airflow, and humidity.

How do cleanrooms work?

Cleanrooms operate by removing pollutants, particles, and contaminants from external air. This process broadly involves the following steps:

1. Air Filtration: External air passes through a filtration system, typically using HEPA or ULPA filters, which clean and decontaminate the air to specified standards.

2. Air Introduction: The filtered air is then introduced into the cleanroom.


3. Positive Pressure: Inside the cleanroom, positive pressure is maintained to create airflow that flushes out contaminants generated by internal activities.

4. Air Recirculation: The contaminated air is either expelled or recirculated back through the filters, repeating the purification process.

Who needs a cleanroom?

You may need a cleanroom for a wide variety of reasons. As a rule, if you’re manufacturing something that is easily affected by contaminants or particles in the air, you’ll likely need a cleanroom. If you're unsure or are looking for more guidance, be sure to contact our expert team, and we'll be happy to discuss your requirements and objectives.

Here are just some of the common sectors that regularly use cleanrooms:

• Semiconductor and battery production

• Life sciences

• Aerospace

• Pharmaceutical

• Medical & healthcare

• Hydrogen fuel cell production

• Injection moulding

• Medicinal cannabis

• Vertical farming

• Automotive

Why are cleanrooms so important?

Cleanrooms are critical across many industries because they provide a controlled environment that minimises the presence of airborne particles, contaminants, and pollutants. Here are just some of the reasons why cleanrooms are essential:

Ensuring Product Quality and Safety: In industries such as pharmaceuticals, biotechnology, and medical devices, even the smallest contamination can compromise product quality and safety. Cleanrooms maintain stringent cleanliness standards, ensuring that products are free from contaminants and safe for use.

Compliance with Regulatory Standards: Many industries are subject to strict regulatory requirements. Cleanrooms help companies comply with these regulations by providing an environment that meets the necessary cleanliness and contamination control standards.

Enhancing Research and Development: In research and development, especially in fields like nanotechnology and advanced materials, cleanrooms are crucial for preventing contamination that could skew experimental results or hinder the development of new technologies.

Supporting Innovation: Cleanrooms enable the development and production of cutting-edge technologies and innovative products. By providing a controlled environment, they allow for the precise manufacturing conditions needed to create advanced materials and components.

Ensuring Patient Safety in Healthcare: In healthcare settings, such as hospitals and laboratories, cleanrooms play a critical role in preventing infections and ensuring the safety of patients. They are used for sterile compounding, surgical procedures, and the preparation of pharmaceuticals.

Enhancing Competitive Advantage: Companies that utilise cleanrooms can achieve higher standards of quality and safety, which can provide a competitive advantage in the marketplace. This can lead to increased customer trust, better regulatory compliance, and a stronger reputation.

In summary, cleanrooms are critical because they ensure product quality and safety, comply with regulatory standards, protect sensitive processes, enhance research and development, improve reliability and longevity, support innovation, ensure patient safety, facilitate contamination control, and enhance competitive advantage. These controlled environments are indispensable for maintaining the high standards required in various advanced industries.
