Manufacturing of sensitive material or environmentally sensitive production processes, scientific research and laboratory work all require environments free of contamination for peak performance and output. Modular cleanrooms are a secure way to create the required clean space necessary for sensitive equipment or materials.
Modular Cleanroom Applications

Packaging Rooms

Modular Isolation Rooms

Controlled Environmental Rooms
ISO Certifications
Prefabricated cleanrooms are typically certified with ISO standards that establish the level of cleanliness that must be maintained inside. These ISO standards require a comprehensive design by an industry expert that takes into account:
- The existing environment.
- Application requirements.
- Mechanical system design.
- Materials used to create the prefabricated cleanroom.
Create a Clean Environment for Sensitive Materials
Porta-King’s modular prefabricated cleanrooms perform just as good as conventionally built cleanrooms with several advantages:
- Precut components for much cleaner initial set up. No need to put up barriers to contain dust and debris common with conventional construction.
- Faster initial set up to start cleanroom operation.
- Flexibility to change as space or application requirements change.
We offer a wide range of construction options to facilitate the design of your cleanroom:
- Different framing and connection methods for panel assembly. This includes aluminum framed systems or tongue and groove side panel connection methods
- A wide array of wall surface finishes like Painted Steel, HPL, PVC and other durable, non-shedding surfaces.
- Custom wall compositions to address thermal ratings and sound attenuation requirements.
Panel thickness ranging from 1 ¾” to 8” to address a range of cleanroom applications. Wall thickness is a factor for a range of design criteria including roof loads, wall height, insulation and sound control.
Based upon these and other design considerations, Porta-King’s experienced team of outside sales support, engineers and customer service are ready to assist you with your next cleanroom project. Our services include:
- System design for space planning
- Mechanical system integration
- Site condition analysis
- Installation
Modular Construction for Clean & Budget Friendly Installation
Manufacturing operations require clean environments to ensure quality and optimize production output, and laboratories rely on clean space to improve output for their experiments and research. Hospitals need to remain clean for health and safety reasons, and manufacturing operations require clean environments to ensure quality and optimize production output. Laboratories rely on clean space to improve output for their experiments and research. Using modular construction helps to achieve all of these goals by providing easy to construct affordable prefabricated cleanrooms.

Frequently Asked Questions
What is a cleanroom used for?
Cleanrooms are used to create a controlled environment, filtering out pollutants such as airborne microbes, dust and aerosol particles, and other debris from manufacturing or otherwise. A cleanroom can be classified by considering the amount of particles allowed per cubic meter. This can be further broken down by their ISO Certification. Cleanrooms can also be utilized to monitor and control variables such as temperature and humidity.Several industries that require regular use of cleanrooms include:
- Manufacturing Companies
- Research Facilities
- Pharmaceutical Companies
- Medical Laboratories
- Electronics Production
- Aerospace Industry
- Nanotechnology
- Optics and Lens Manufacturing
- Military Applications
What do cleanroom classifications mean?
Cleanroom classifications are determined by the quantity and size of particulates that can be measured in a cubic meter of space. These measurements are used to establish the classification and requirements for the cleanroom. Filters are used to control the amounts of particulates; the number and type of filters will vary depending on the classification level requirements.Do all cleanrooms need to be certified?
No, not all cleanrooms need to be certified. Certification is used to confirm a level of cleanliness to meet compliance for certain manufacturing processes, OEM specifications, and regulatory standards or to ensure optimal equipment performance. In some cases, the term cleanroom simply means the creation of a cleaner environment than what currently exists inside a facility. In these applications, certification is typically not required.What construction features are critical to a cleanroom’s performance?
