Cleanroom Classifications

Cleanrooms are classified as a room in which the concentration of airborne particles is controlled. It must be constructed and used in a manner that minimises the introduction, generation, and retention of particles & microbes inside the room and in which other relevant parameters, such as; temperature, humidity, and pressure, for example, are controlled as necessary.

Planning a cleanroom is quite a comprehensive process during which you must pay attention to different things. For example:

How to Choose a Suitable Cleanroom

1. Consider the Cleanroom Requirements

It is essential to define your cleanroom requirements to ensure you’re getting what you need. This will depend on your industry and the number of particles permitted in the area where the product is being manufactured. Keep in mind that even the smallest particles may cause severe issues.

2. Pick Adequate Ventilation System

The right ventilation system depends on the ISO class your cleanroom must comply with. The airflow plays a vital role in the cleanroom’s cleanliness level, and it should be created to prevent particle deposition at any critical points. Consider air conditioning units to regulate temperature and humidity in the cleanroom.

3. Select the Right Material for Ceilings, Floors, and Walls

The materials for cleanroom ceilings, walls, and floors should be easy to clean and resistant to the chemicals cleaning agents contain.

Cleanroom cleaning is another critical thing to consider because it must be performed by specialists. Ensure you’re planning the cleaning and maintenance cycles in advance according to your cleanroom classification and requirements.

4. Pay Attention to the Furniture Inside the Cleanroom

As a general rule of thumb, the surfaces for seating you keep in the cleanroom should be abrasion-resistant and mustn’t be made of fabrics. As for tables, and storage furniture, consider stainless steel, melamine coating, or various types of plastics.

5. Don’t Forget the Right Protective Clothing for Your Staff

People naturally carry a significant amount of contaminants, which is why it’s important to wear protective clothing while in the cleanroom. The exact cleanroom garments the staff will have to wear depends on the cleanroom classifications. For instance, ISO 6 classification requires a face mask, a full-body overall, special shoes and gloves, safety goggles, etc.

Save Costs with a Controlled Environment

Often it is possible to utilise a lower ISO level cleanroom by garmenting people to a higher level, and understanding where contamination is coming from. Where return air grills and filtration are located can achieve cleaner areas within a clean room, and takes the overall cleanroom to a lower ISO level. This will save significant cost from both construction and operational standpoints.
