Modular Cleanroom Sizes Revealed: Custom Flexibility for Labs to 1000m² Factories

One of the core advantages of modular cleanrooms is their “flexible and adjustable dimensions.” There is no absolute fixed standard size; instead, they are customized based on site conditions, industry requirements, and cleanliness levels. They routinely cover everything from small laboratories of a few square meters to large production workshops of over a thousand square meters, adapting to diverse cleanroom needs globally.

Boben Modular Cleanroom Manufacturers, with 14 years of deep industry experience and modular prefabrication technology at its core, provides full-process services from dimension planning to final delivery, ensuring cleanroom dimensions perfectly fit the customer’s actual usage requirements.

I. Core Standard Size References

1.Small-Scale Modular Cleanrooms (Suitable for Labs/Sample Production)

• Standard Dimensions: Length 3–8m × Width 2–5m × Height 2.4–2.7m
• Typical Applications: Biological sample testing labs, small electronic component assembly areas, vaccine R&D pilot workshops.
• Features: Can be used as a standalone single cabin or spliced into multiple cabins. Does not require large surface areas; flexible installation suitable for space-constrained scenarios.

2.Medium-Scale Modular Cleanrooms (Suitable for Batch Production/Medium Workshops)

• Standard Dimensions: Length 8–20m × Width 5–15m × Height 2.6–3.0m
• Typical Applications: Medical device batch production workshops, food aseptic filling areas, electronic device packaging workshops.
• Features: Supports zoned design (e.g., Clean Area, Buffer Zone, Gowning Area), reserves space for equipment installation and personnel flow, balancing efficiency with compliance.

3.Large-Scale Modular Cleanrooms (Suitable for Mass Production/Multi-Process Workshops)

• Standard Dimensions: Length 20–50m × Width 15–30m × Height 2.8–4.5m
• Typical Applications: Chip manufacturing workshops, large pharmaceutical production lines, aerospace precision component processing areas.
• Features: Uses multi-module splicing design to divide multiple cleanliness class areas. Supports complex equipment layouts and assembly line operations; height can be increased as needed to accommodate ceiling-mounted purification equipment.

4.Other Component Dimensions The dimensional design of modular cleanrooms follows international standards. Core components include:

Ceiling Grid & FFU (Fan Filter Units)

• Ceiling Standard Size:1185mm (length) × 902mm (width).Uses high-strength aluminum alloy frames coated with anti-static finish to ensure uniform airflow distribution.
• FFU Size:1175 mm (L) × 875 mm (W) × 325 mm (H).Built-in high-efficiency filters (HEPA/ULPA) with filtration efficiency over 99.99%. The ceiling grid is slightly larger than the FFU to reserve installation frame space and ensure sealing.

Enclosure Wall Panels & Glass

• Wall Panel Standard Width:1182 mm. Features a double-layer steel plate sandwich structure filled with fireproof rock wool; sound insulation exceeds 50 dB.
• Glass Standard Width:903 mm, thickness 8 mm. Tempered treatment increases impact resistance by 5 times; transparency reaches over 90%.

Air Shower Dimensions

• Single-Person Air Shower:External: 1200 mm (W) × 1000 mm (D) × 2100 mm (H). Internal: 800 mm (W) × 800 mm (D) × 2000 mm (H). Suitable for rapid single-person passage.
• Double-Person Air Shower:External: 1400 mm (W) × 1500 mm (D) × 2100 mm (H). Internal: 1000 mm (W) × 1000 mm (D) × 2000 mm (H). Supports simultaneous purification for two people.

II. Dimension Customization Logic: No Fixed Limits, Adapted on Demand

The core of modular cleanroom dimensions is “Customization.” Boben Modular Cleanroom Manufacturers follows these principles to ensure precise dimensional adaptation:

III. Key Factors Influencing Dimensions

• Cleanliness Class: High cleanliness rooms (ISO 1–5) require larger spaces to install unidirectional flow purification systems and HEPA filters. Dimensions are slightly larger than ISO 6–9 rooms for the same function.
• Equipment Layout: Large production equipment (e.g., bioreactors, precision detectors) occupies more space and requires reserved channels for moving and maintenance.
• Personnel & Material Flow: Multi-person operations require sufficient operating space (1.5–2.0 m² per person). Cross-zone transfers necessitate buffer zones, which impact overall dimensions.
• Auxiliary System Configuration: The inclusion of gowning rooms, air showers, and pass boxes affects dimensions. Auxiliary areas typically account for 20%–30% of the clean area.

IV. Typical Application Case Studies (Boben Project References)

1. Electronics Industry (ISO Class 6, 120m²): 15m (L) × 8m (W) × 2.8m (H). Includes clean production area, material buffer zone, and gowning area. Adapted for 3 electronic component assembly lines.

2.Pharmaceutical Industry (ISO Class 7, 80,000 sq ft): 10 m (L) × 8 m (W) × 2.7 m (H). Includes sterile production area, sampling room, and air shower. Meets GMP compliance requirements.

3.Research Laboratory (ISO Class 5, 30m²): 6m (L) × 5m (W) × 2.6m (H). Single-cabin design equipped with ultra-high efficiency filtration systems. Adapted for biological sample sequencing experiments.

4.Food Industry (ISO Class 8, 200 m²): 20 m (L) × 10 m (W) × 2.9 m (H). Includes raw material pre-treatment area, filling area, and finished product temporary storage. Reserves space for automated conveyor lines.

V. Boben Modular Cleanroom Dimensional Advantages

Leveraging modular technology, Boben Modular Cleanroom Manufacturers showcases three core highlights in dimensional adaptation:

• No Space Limits: Customizable from a few square meters to thousands of square meters. Whether for local indoor renovation or independent outdoor construction, we match it precisely.
• Rapid Site Adaptation: Prefabricated components are produced precisely to site dimensions. On-site assembly requires no alteration to the original building structure, saving construction time.
• Flexible Expansion: The modular structure allows for the addition or removal of cabins at any time. Expansion does not require work stoppages, ensuring existing production and research schedules are unaffected.

VI. Customer Guarantee & Customization Process

• Free Site Survey: Boben’s professional team visits on-site or evaluates via blueprints to assess site conditions, producing a preliminary dimension planning scheme based on client needs.
• Precise Solution Design: Detailed L×W×H dimensions and internal partitioning are finalized based on cleanliness levels, equipment layout, and personnel needs, provided with 3D renderings and detailed dimension lists.
• Global Delivery Adaptation: Supports site dimension standards for different global regions (Metric/Imperial). Equipment and installation comply with local building codes.
• Full-Process Service: From dimension planning and manufacturing to installation and commissioning, a professional team follows up throughout the process to ensure dimensions perfectly match actual requirements.
