Cleanrooms are available in a variety of designs. Each design comes with its own unique features and benefits, and the one that best suits your needs will depend on your industry and critical processes. Your industry and critical process will determine the specific materials and level of cleanliness your cleanroom must possess.

What negatively impacts the level of cleanliness of a cleanroom the most is the personnel. The contamination from personnel is generally generated by particulates shed either from skin, hair, or clothing. These particulates are too small to see, but are yet large enough to contaminate the sensitive processes in the cleanroom.

To ensure cleanliness in a cleanroom, it is crucial that source or sources of contaminants are first isolated with proper cleanroom garments. But even when effectively isolated, personnel will still shed particles.

Most of these particles will be too small and light to fall to ground and will instead be circulated in the air. To combat this, laminar airflow will be used to move the air and particles to the ground and prevent it from being suspended in the cleanroom atmosphere. Laminar airflow will be generated from the ceiling. Its effectiveness will be determined by the combination of HEPA-filtered diffusers and an effective HVAC system. The air pushed to the ground will be removed from the cleanroom through the floor’s perforated tiles.

This design of a cleanroom can be for either production or research purposes, but it is better suited for production. A research cleanroom where tools are constantly changed will better benefit from a “bay and chase” cleanroom with clean spaces and return air spaces in alternation. The alternation apparent in a bay and chase cleanrooms is what gives the design its distinctive interlocking “finger” appearance.

Modular Cleanroom Benefits

  • Modular Construction
  • Quick Assembly Time
  • Versatility
  • Reconfiguration
  • Airflow Control
  • Inexpensive Modifications

Clean Room Design Standards

For organisations in certain industries that need to adhere to design standards when it comes to cleanrooms, it is crucial that the cleanroom is built and used in line with the provided cleanliness classifications

The International Organization for Standardization (ISO) is the leading authority for cleanroom classifications. ISO 14644 classifies a cleanroom according to the number and size of airborne particles per cubic meter of air. In order for a cleanroom to achieve desired cleanliness, the cleanroom’s air will be purified using HEPA (High Efficiency Particulate Air) filters which remove from the air particles as small as 0.5 microns.

Single Pass Design

Using this design, ambient air will be filtered into the cleanroom and out into outside building space. This design is typically used in environments that have no need for humidity and temperature control.

Recirculating Air Design

This design conditions the air with the aid of air handling units and extracts it via low wall returns and into the ceiling plenum. Cleanrooms with temperature or humidity control needs typically use this design. It also provides an enabling environment for greater process control.

Modular Cleanroom Designs

Modular cleanroom design to be installed will primarily depend on industry standards and production requirements that govern your company. What components will be installed in the cleanroom, as well as details such as surface finish and materials are all decided in the early stages of design. The modular cleanroom design may be a mono-block system or modular wall system.

  • The Mono-block System: This will typically consist of two metal ceiling sheets or facing walls machined to tight tolerances. These components are treated and powder coated to match the desired cleanroom requirements. Organisations in the pharmaceutical industry typically utilise this type of cleanroom design. But they may also be used for heavy duty construction.

Advantages of mono-block systems include suitability for high-end cleanrooms, insulation features, made of solid structures and features smooth surfaces and flush joints.

  • Modular Wall System: This is a double or single shell framed wall system. These types of cleanroom are typically constructed with aluminium or glassware, or other panel types and are generally best suited for sensitive application such as the manufacturing of semiconductors. The chief benefit of this design is that it is flexible and can be easily adapted to suit changing needs or requirements of a company.

Other advantages of modular systems include low cost of production, and are suitable for high cleanroom classes

Softwall Cleanroom Modular Construction

Maintenance of softwall cleanrooms is relatively straightforward, but thorough cleaning is required to maintain optimum performance. Softwall modular cleanrooms are often used because of the reduced running expense and increased flexibility. Like most modular designs, they are like tents and possess easy to assemble, lightweight components. These components can be installed suspended from the ceiling or as a free-standing structure.

Most softwall cleanrooms are small enough to fit into tight spaces. Their portability makes disassembling and transportation of its components from location to location far easier. The low cost of production and installing a modular cleanroom also makes it suitable for startup businesses or organisations in need of a fast and effective method to expand their cleanroom services. Like Hardwall cleanroom designs, Softwall cleanrooms are available in a variety of design options and can be tailored to suit the unique needs of individual organisations. The design can also be expanded on with necessary components such as gowning rooms, lockers, anterooms, or other necessary features.

Softwall cleanrooms can be easily moved along an existing cleanroom’s perimeter for adaptation or alternation to production processes. If equipped with elective braked casters, the cleanroom can be conveniently transported to a different location within the same premises
