Specifications & Models
Features & Control
The rigid hardwall enclosure delivers high‑level airtight separation between the clean zone and surrounding non‑controlled areas. Fully sealed flush wall and ceiling panels build a robust permanent cleanroom structure, configurable to match room dimensions, equipment layout, personnel flow and material flow for positive pressure operation.
The air filtration system can be configured with H13 HEPA filters, with H14 options available when required by pharmaceutical or medical‑device project specification. FFU or centralized AHU configurations deliver balanced supply air to sustain positive pressure, while filter access supports inspection, maintenance and replacement with minimal disruption to cleanroom operations.
Smooth, flush‑mounted wall and ceiling panels reduce ledges and hard‑to‑clean interfaces where particles may accumulate. Panel materials, surface finishes and sealed joint details can be selected according to cleaning regimes, chemical exposure, fire‑safety requirements and the intended positive‑pressure operating environment.
Airtight cleanroom doors, observation windows and pass‑through boxes integrate into the hardwall system to support controlled personnel and material movement. Door seals, interlocking functions and window configurations are selected based on positive‑pressure relationships, traffic volume and site‑specific operational requirements.
The ventilation and control system maintains stable outward positive‑pressure gradients and required airflow patterns for ISO 5‑8 hardwall cleanrooms. Adjustable fan speed, differential‑pressure monitoring and alarm functions support stable barrier performance, energy management and timely response to abnormal pressure drift.
Monitoring and control options cover room positive differential pressure, temperature, relative humidity, fan status and filter loading condition. The system provides visual status information and configurable alarms, helping operators identify deviations and maintain documented GMP‑aligned operating conditions during routine production.
Cleanroom LED lighting, electrical services and selected process utilities integrate within wall and ceiling layout. Purpose‑built sealing minimises pressure‑driven air leakage and simplifies cleaning, inspection and future maintenance of the positive‑pressure controlled space.
Project documentation includes layout drawings, equipment information, operation and maintenance manuals, filter data and commissioning records. After installation, tests including particle counting, HEPA filter integrity, airflow balance, positive differential pressure, temperature and humidity are completed per project specification and ISO 14644 on‑site validation requirements.
Application Scenarios
Pharmaceutical Manufacturing & Packaging
Challenge: Pharmaceutical production, weighing, packaging and inspection areas require controlled airborne particle levels and protection from contamination entering from adjacent spaces.
Solution: The Positive Pressure Hardwall Cleanroom uses a sealed rigid enclosure, HEPA-filtered air and a controlled pressure cascade to support contamination control in selected pharmaceutical processes. It can be configured for material preparation, dispensing, secondary packaging, visual inspection and controlled storage. The required ISO classification, pressure differential, air-change rate, temperature, humidity and qualification criteria should be established according to the product, process and applicable GMP requirements.
Medical Device Assembly & Packaging
Challenge: Medical device manufacturing areas need to limit airborne contamination while maintaining cleanable surfaces, controlled personnel flow and reliable separation from surrounding production spaces.
Solution: A Positive Pressure Hardwall Cleanroom can be designed for medical device assembly, component cleaning, inspection, packaging and temporary storage. Rigid wall panels, sealed joints, HEPA filtration, cleanroom doors and pass-through systems help create a stable controlled environment. Pressure relationships and room classification should be selected according to product sensitivity, process risk, cleaning procedures and the approved quality-management requirements.
Electronics & Precision Component Manufacturing
Challenge: Dust, uncontrolled airflow and particles from adjacent areas may affect the assembly, testing, inspection and packaging of sensitive electronic and precision components.
Solution: The Positive Pressure Hardwall Cleanroom provides a rigid, sealed working area supplied with HEPA-filtered air. Positive pressure helps reduce the risk of unfiltered air entering the room through normal leakage paths, while smooth hardwall surfaces support routine cleaning. Where electrostatic discharge is a concern, grounding, conductive or dissipative materials, ionization and ESD operating procedures should be incorporated into the complete project design.
Precision Optics & Optical Instrument Assembly
Challenge: Optical lenses, imaging components and precision instruments can be affected by airborne particles during cleaning, assembly, alignment, testing and final inspection.
Solution: A Positive Pressure Hardwall Cleanroom creates a stable, low-particle environment for optical component preparation, precision assembly, inspection and related process activities. The sealed hardwall enclosure supports effective cleaning and controlled personnel and material movement. Lighting quality, vibration control, temperature stability, humidity limits and process-specific cleanliness requirements should be evaluated separately for high-precision optical applications.
Laboratories & Controlled Research Areas
Challenge: Research, testing and product-development facilities may require a dedicated controlled environment that protects sensitive work from surrounding laboratory or production conditions.
Solution: The Positive Pressure Hardwall Cleanroom can support sample preparation, material handling, laboratory testing, equipment integration and controlled research activities where airborne particle control is required. Modular rigid construction allows the room size, service points, observation windows, pass boxes, monitoring devices and access arrangements to be coordinated with the workflow. Future expansion, equipment heat loads and the required qualification program should be considered during the design stage.
Semiconductor, Battery & Advanced Materials Processing
Challenge: Semiconductor, battery and advanced-materials processes may be sensitive to airborne particles, moisture, temperature variation and contamination transferred from personnel or adjacent operations.
Solution: A Positive Pressure Hardwall Cleanroom can be engineered for selected material preparation, component assembly, inspection, testing and packaging operations. HEPA filtration, pressure control, cleanable rigid panels and monitored environmental conditions help support a consistent process area. Depending on the application, the design may also require humidity control, ESD protection, chemical compatibility, fire-safety measures, exhaust systems or additional process containment. These requirements must be confirmed through a documented user-requirements and risk-assessment process.
Application and qualification note: A Positive Pressure Hardwall Cleanroom is not defined by room construction alone. Cleanroom performance depends on the coordinated design of the enclosure, HVAC system, HEPA filtration, pressure cascade, airflow distribution, doors, material-transfer procedures, cleaning program and facility maintenance. The final ISO classification and operating performance should be verified through documented commissioning and qualification testing, which may include airborne particle counting, HEPA filter integrity testing, airflow measurement, pressure-differential testing, temperature and relative-humidity verification, recovery testing and alarm checks according to the approved project requirements.
