What are the Dimensions of a Modular Cleanroom? Standard vs. Custom Sizes

The core dimensional design philosophy of modular cleanrooms is “standard base + customized adaptation.” This approach breaks free from the constraints of traditional fixed-structure cleanrooms while precisely matching spatial and functional requirements across diverse scenarios. This flexibility is key to their widespread adoption in precision manufacturing across Europe and America, as well as high-temperature industrial settings in the Middle East. boben Modular Cleanroom Manufacturers has deepened its presence in global markets, optimizing its dimensional systems to suit regional site characteristics while balancing compliance and practicality. This makes it the preferred solution for cross-regional projects.

From a fundamental specification perspective, modular cleanrooms feature clearly defined standardized dimensions suitable for most common applications. Standard widths center around 1.2 meters, 1.5 meters, and 2 meters, while lengths can be extended in 1-meter increments from 2 meters up to 10 meters. Standard heights range from 2.2 meters to 3 meters, aligning with common industrial ceiling heights in Europe, America, and the Middle East while meeting fundamental requirements for HEPA filter installation and airflow circulation. The advantage of these standardized dimensions lies in streamlined transportation—modules can be disassembled into prefabricated units for container shipping, significantly reducing international logistics costs. This makes them particularly suitable for cross-border projects in the Middle East. Refer to the table below for specific dimensional parameters and applicable scenarios:

Type	Width Range	Length Range	Height Range	Core Application Scenarios
Standard model	1.2m/1.5m/2m	2m–10m (1m increments)	2.2–3.0 meters	Industrial applications common in Europe, America, and the Middle East, such as food packaging and general electronics assembly.
Customized Version (Precision Industry)	≤4m	≤20m	≤4m	The semiconductor and medical industries in Europe and the United States require compatibility with vertical laminar flow systems and large-scale equipment.
Customized (Special Venues/Climate)	Starting at 1.2m (allowing for 10% insulation width)	Customized on demand	≥2m	High-temperature environments in the Middle East, renovation of old factory buildings (narrow/low-ceiling scenarios)

Based on the aforementioned standard dimensions, customized solutions can further push boundaries to address various specialized scenarios—a core competency of boben Modular Cleanroom Manufacturers. For the precision requirements of the semiconductor and medical industries in Europe and America, large modules up to 4 meters wide and 20 meters long can be customized, with height increased to 4 meters to accommodate vertical laminar flow systems and large testing equipment installations. For the high-temperature, arid environments of the Middle East, designs incorporate a 10% extra width allowance to accommodate high-density insulation layers and high-efficiency cooling equipment. This approach maintains internal operational space while adapting to extreme climates. Additionally, narrow sites (such as retrofitted older factories) can utilize 1.2-meter narrow modules, while low-ceiling scenarios allow height reduction to 2 meters, maximizing utilization of existing space.

Customized dimensions are central to addressing specialized scenarios and represent one of boben Modular Cleanroom Manufacturers’ core competitive strengths. To meet the precision requirements of the semiconductor and medical industries in Europe and America, large modules up to 4 meters wide and 20 meters long can be customized, with height increased to 4 meters to reserve installation space for vertical laminar flow systems and large-scale testing equipment. For the high-temperature, arid environments of the Middle East, designs incorporate a 10% extra width allowance to accommodate high-density insulation layers and high-efficiency cooling equipment. This approach maintains internal operational space while adapting to extreme climates. Additionally, narrow sites (such as retrofitted older factories) can utilize 1.2-meter narrow modules, while low-ceiling scenarios allow height reduction to 2 meters, maximizing utilization of existing space.

When selecting dimensions, three core factors must be prioritized to avoid blind customization. First, industry compliance requirements: European and American Class 100 cleanrooms require uniform airflow coverage, with a minimum height allowance of 2.5 meters for HEPA filter layout. Middle Eastern food processing cleanrooms, though lower-grade, necessitate sufficient width to accommodate disinfection equipment workflow. Second, site constraints: Column spacing and door/window locations directly dictate module assembly lengths. For some Middle Eastern open-air retrofits, dimensions must also accommodate sunshade structures. Third, future scalability: Modular cleanrooms can be bolted together for expansion. Establish foundational dimensions based on initial needs, then add 1-2 meter modules later for capacity increases without requiring complete reconstruction.

In actual projects, dimensional adaptability directly impacts implementation efficiency. A German semiconductor factory with a ceiling height of only 2.1 meters could not accommodate traditional cleanrooms. Boben Modular Cleanroom Manufacturers customized 2-meter-high modules and optimized filter installation angles, meeting Class 1000 requirements without altering the original factory structure. Assembly and commissioning were completed in 12 days. A vaccine plant in Dubai faced warehouse space constraints, requiring a cleanroom within a 5m × 6m area. Customized modules measuring 1.5m wide and 5m long were installed, incorporating an automated filling equipment passageway while accommodating insulation space for the local high-temperature environment. Post-commissioning, no dimensional adaptation issues arose.

There is no fixed standard for modular cleanroom dimensions; the core principle is “standard configurations control costs, while custom designs solve challenges.” Whether addressing Europe and America’s stringent demands for precision and compliance or the Middle East’s unique climate and site requirements, comprehensive planning tailored to specific scenarios is essential. Its flexible sizing system not only reduces upfront construction costs but also leaves ample room for future capacity upgrades, making it the mainstream choice in the global industrial cleanroom sector.
