Overview
The AIRTECH Sujing Antai Dual-Door Air Shower is an engineered personnel decontamination system designed for controlled environments requiring strict particulate control—such as ISO Class 5–8 cleanrooms, pharmaceutical manufacturing suites, microelectronics fabrication areas, and biotechnology laboratories. Operating on the principle of high-velocity laminar air impingement, the unit removes loose particulates from personnel garments and surfaces via precisely directed airflow from 16 adjustable stainless-steel nozzles. Each nozzle delivers ≥25 m/s air velocity, generated by a compact, high-efficiency centrifugal blower housed within an ultra-slim cabinet. The dual-door interlocked configuration ensures continuous environmental separation: one door must remain closed before the other can open, preventing cross-contamination between non-classified and classified zones. This architecture complies with fundamental cleanroom zoning requirements defined in ISO 14644-1 and supports facility validation under GMP Annex 1 and FDA Guidance for Industry: Sterile Drug Products.
Key Features
- Ultra-slim cabinet and blower assembly—optimized footprint without compromising airflow performance or structural rigidity.
- 16 rotatable, recessed stainless-steel nozzles enabling full-body coverage and adaptable spray angle alignment to suit operator height and gowning protocols.
- Multi-programmable logic controller (PLC) with embedded operational sequences—including timed blow cycles (adjustable 0–99 s), automatic door interlock verification, and fault diagnostics.
- Intuitive human-machine interface (HMI) with real-time status display: door position, filter differential pressure, cycle completion, and system alarms.
- Modular construction using standardized panels and pre-wired components—enabling rapid on-site assembly, minimal civil works, and simplified component-level maintenance.
- Configurable functionality: optional integration with building management systems (BMS) via dry-contact or Modbus RTU; support for RFID badge authentication and audit trail logging (when paired with compatible access controllers).
Sample Compatibility & Compliance
The AIRTECH Dual-Door Air Shower does not process samples or materials directly but serves as a critical engineering control at personnel entry/exit points. It is compatible with standard cleanroom garments (e.g., bouffant caps, coveralls, boot covers) and validated for use with ISO 14644-3:2019 particle counting methodologies. Filter assemblies meet EN 1822-1:2019 classification for H14 HEPA filters (≥99.995% efficiency @ 0.3 µm MPPS). Unit installation follows ISO 14644-4:2022 guidelines for cleanroom equipment placement and airflow integration. Documentation packages include Factory Acceptance Test (FAT) reports, filter integrity test records (DOP/PAO scan), and electrical safety certification per GB/T 14048.1 and IEC 60204-1.
Software & Data Management
The onboard PLC supports event-driven data logging of all operational parameters—including door actuation timestamps, cycle duration, total runtime hours, and filter pressure drop trends. Data export is available via USB port in CSV format for offline analysis. When integrated into a compliant infrastructure, the system supports electronic record retention aligned with 21 CFR Part 11 requirements—provided external validation of user access controls, audit trails, and electronic signatures is implemented at the facility level. Firmware updates are performed locally via secure USB upload; version history and change logs are retained in non-volatile memory.
Applications
- Personnel airlocks in sterile pharmaceutical filling lines (e.g., aseptic processing suites per EU GMP Annex 1).
- Entrance vestibules for semiconductor photolithography cleanrooms (Class 100 / ISO 5).
- Access control points in cell and gene therapy manufacturing facilities operating under CGMP conditions.
- Research laboratory anterooms supporting nanomaterial handling or high-sensitivity analytical instrumentation.
- Medical device packaging cleanrooms requiring ISO 13485-aligned environmental controls.
FAQ
What is the recommended filter replacement interval?
Filter service life depends on ambient particulate load and usage frequency; typical replacement is scheduled every 6–12 months, verified by differential pressure monitoring and upstream particle challenge testing.
Can this unit be installed in an existing wall opening?
Yes—the modular design allows retrofitting into standard wall cavities; dimensional allowances (W₁+400, D₁+100, H₁+90) ensure clearance for ductwork, wiring, and service access.
Is the unit certified for explosion-proof environments?
Standard configuration is not ATEX or IECEx certified; however, custom variants with intrinsically safe components and non-sparking materials can be supplied upon request and subject to site-specific hazard analysis.
Does it support remote monitoring via Ethernet or Wi-Fi?
Native Ethernet or Wi-Fi connectivity is not included; however, optional gateway modules enable Modbus TCP or BACnet/IP communication for centralized facility monitoring systems.
What documentation is provided for regulatory submissions?
Standard delivery includes Installation Qualification (IQ) templates, Operation Qualification (OQ) test protocols, filter certification reports, electrical schematics, and compliance statements referencing ISO, GB, and IEC standards applicable to cleanroom equipment.
