Cleanroom Planning

This is an area where an exceptionally high level of cleanliness is maintained. It does not refer to standard visible cleanliness from waste and dirt, but rather to a level measured by the number of airborne particles per cubic meter. In a cleanroom, the focus is on the concentration of 0.5-micron particles per cubic meter of air.

The cleanroom is used by various industries that require strict control of dust particles during the production process. A properly functioning cleanroom must maintain a maximum level of cleanliness, even from the tiniest particles invisible to the naked eye. Each industry has a mandatory standard that the cleanroom must comply with, defined according to its production purpose.

The sterile space defined as a cleanroom is not a conventional environment. It requires the use of specialized equipment and protocols for anyone entering. The appropriate gear enables maintaining professional workflows and high levels of cleanliness. The cleanroom is constantly monitored using instruments that ensure real-time verification of its cleanliness level.

To assess the level of cleanliness in the cleanroom, several critical parameters are tested — including pressure relative to atmospheric pressure, particle count, temperature, and humidity.

Before constructing a cleanroom, several questions must be asked in order to properly define its requirements:
What is its purpose? What processes will take place inside? What components and infrastructure are necessary for its proper operation? What regulations apply to the intended activity?

Each industry has its own specific standards and requirements. In the pharmaceutical industry, for example, there is a strict emphasis on cleanliness to prevent conditions that allow bacterial growth. In the electronics industry, the focus is on the number of airborne particles and humidity levels. All of these factors require precise infrastructure planning.

Cleanroom planning involves multiple stages and is carried out with the involvement of various professionals — from the initial layout and design to final completion. During ongoing operations, it is essential to maintain the environmental conditions required for the cleanroom to function properly, such as particle count, temperature, noise levels, lighting, and more.

The cleanroom is built inside a production facility, in an area where a high level of cleanliness is required. Employees entering the cleanroom wear specialized garments that do not release particles. They also wear face masks that filter the air they exhale into the room. All tools used inside the cleanroom undergo quality control and are approved for sterile environments.

In addition, employees must follow strict work procedures that define behavior before entering the cleanroom, while inside, when using equipment, when exiting, and during emergencies. Workers undergo comprehensive training and periodic refresher courses on the protocols.

A factory seeking to establish a cleanroom wants peace of mind — knowing that the process is carried out professionally by top-tier experts, ensuring that sensitive products and processes can be handled efficiently under controlled environmental conditions. Certified engineers enable the planning process to be conducted in parallel with the architectural design. Every stage of planning must incorporate the requirements of both the Israeli and U.S. Ministries of Health.

In addition, the client’s unique needs must be considered — the required conditions must be clearly defined, and the cleanroom should be planned accordingly.

Therefore, when choosing a cleanroom design company, experience is the most critical factor. It is essential to review past projects, read client testimonials, and evaluate the range of services offered. A comprehensive service package typically includes in-depth consulting and full project support from the planning stage.

The construction phase usually includes building the structure, offices, laboratories, and final finishing works. At the end of the process, the facility undergoes performance testing and certification. The entire project is coordinated between all involved service providers to ensure seamless execution.
