Choosing the right cleanroom requires a clear understanding of your business’s operational needs and the applicable standards and regulations in order to accurately define the required quality standards. This makes careful planning essential, taking into account all intended uses and requirements, as well as local conditions. The aim is to ensure that the controlled environment is successfully adapted to the specific operational needs of the business.
With this in mind, here are six key factors to consider when choosing the right cleanroom.
Analyse Your Business Needs
The design and implementation of an appropriate cleanroom should be based on a thorough assessment covering the following aspects:
- Industry and application.
- Business operating environment.
- Applicable regulations and standards.
- Investment and operating costs.
- Number of personnel involved.
- Available space and dimensions.
This makes it possible to align the technical requirements of the controlled environment with the specific needs of the business, while ensuring regulatory compliance and taking costs and resources into consideration.
Define the Cleanroom Requirements
Depending on the cleanroom application and the needs of the business, the specific requirements of the controlled environment must be clearly defined. Applicable standards should be taken into account, such as DIN EN ISO 14644-1, which establishes the classification of air cleanliness by particle concentration.
This classification is based on the concentration of airborne particles and considers particle sizes within a defined range, depending on the intended use and type of business. In other words, the requirements will depend on the processes carried out and the permitted particle concentration within the manufacturing area. In the pharmaceutical industry, GMP guidelines must also be considered, including criteria relating to particle concentrations and maximum permitted microbial contamination levels.
Select the Right Ventilation System
The selection of an appropriate ventilation system is closely linked to the required air cleanliness classification. Regardless of the application, airflow should be designed to prevent particles from settling in critical areas.
Air-conditioning systems should also incorporate the necessary equipment to control temperature and humidity. This enables environmental parameters to be monitored while ensuring compliance with the applicable standards.
Choose the Right Cleanroom Materials and Access Systems
Ceilings, walls and floors must be made from materials suitable for use in cleanroom environments.
These materials should be easy to clean and resistant to the chemicals contained in cleaning and disinfection products.
The type of access to the cleanroom must also be determined in accordance with the applicable regulatory requirements. In general, these controlled environments use airlocks between areas with different cleanliness classifications, depending on the industry and intended application.
Assess Furniture and Personnel Protective Clothing
As a basic requirement, seating surfaces used within a cleanroom should be abrasion-resistant. Tables and other furniture should be made from suitable materials such as stainless steel, melamine-coated surfaces or appropriate plastics.
Selecting the correct protective clothing for personnel is also essential, as people are one of the main sources of contamination within a cleanroom. Garment requirements will depend on the room’s particle cleanliness classification.
Establish Cleanroom Cleaning and Maintenance Protocols
The effective operation of a cleanroom is closely linked to hygiene standards and appropriate measures to preserve its condition.
Regular cleaning and maintenance cycles should therefore be planned according to the processes carried out and the required air cleanliness classification. The objective is to ensure that contamination within the controlled environment remains within the limits established by the applicable standards.
These measures also help keep the facility in good condition, prevent deterioration and maintain the original design criteria over time. Choosing the right cleanroom requires technical expertise and specialised solutions to ensure that the facility is fully adapted to the operational environment and the specific needs of the business.
