Overview
The SuJing AnTai Air Shower Unit SS-AS-01 and SS-AS-02 are engineered for personnel decontamination at the entry points of cleanrooms classified to ISO Class 5 (Class 100) and higher. These units operate on the principle of high-velocity laminar airflow—generated by integrated centrifugal blowers—to dislodge and remove particulate contamination (≥0.3 µm) from garments, gloves, and footwear before personnel ingress. The system complies with core cleanroom hygiene protocols defined in ISO 14644-1 and supports facility compliance with GMP Annex 1 (EU), FDA 21 CFR Part 211, and ISO 14644-3 validation requirements for air shower performance verification. Unlike conventional tunnel-style air showers, the SS-AS series features an ultra-slim enclosure architecture (depth: 1000 mm), enabling installation in space-constrained anterooms without compromising airflow dynamics or dwell time efficacy.
Key Features
- Ultra-compact structural design (1040 × 1000 × 2000 mm) maximizes floor-space efficiency while maintaining full-height personnel clearance and optimal nozzle-to-body standoff distance.
- Eight strategically positioned, fully rotatable stainless-steel nozzles ensure uniform 360° coverage; each nozzle delivers ≥20 m/s air velocity under nominal operating conditions, exceeding the minimum 18 m/s threshold recommended in IEST-RP-CC003.4 for effective particle removal.
- Integrated HEPA filtration system (≥99.99% @ 0.3 µm) meets ISO 16890:2016 and EN 1822-1:2019 standards; filter housing is sealed per ISO 14644-3 Class 5 leakage limits.
- Intelligent control panel with multi-program logic enables configurable cycle duration (10–99 s), interlocked door sequencing, and real-time status monitoring—including blower operation, filter differential pressure, and door position feedback.
- Modular construction using powder-coated steel, anodized aluminum extrusions, and tempered safety glass facilitates rapid field assembly, tool-free panel access, and simplified HEPA replacement—reducing mean time to repair (MTTR) during routine maintenance.
Sample Compatibility & Compliance
The SS-AS-01/02 is designed exclusively for personnel decontamination—not material or equipment pass-through—and is validated for use with standard cleanroom garments (e.g., Tyvek® coveralls, nitrile gloves, bouffant caps). It supports operational alignment with ISO 14644-7 (cleanroom furnishing), ISO 14644-14 (cleanroom design for contamination control), and EU GMP Annex 1 §4.35–4.38 on air shower qualification. Units undergo factory pre-commissioning including airflow visualization (smoke wire testing), nozzle velocity mapping (ISO 14644-3 Annex B), and interlock logic verification. Documentation packages include IQ/OQ templates compliant with ALCOA+ data integrity principles.
Software & Data Management
The embedded microcontroller supports audit-trail-enabled operation logs (cycle count, start/stop timestamps, fault codes) stored locally for ≥12 months. Optional RS-485 Modbus RTU interface allows integration into facility-wide SCADA or MES platforms for centralized event logging and preventive maintenance scheduling. All firmware updates are digitally signed and traceable per IEC 62443-3-3 security requirements. Data export is available via USB port in CSV format, compatible with statistical process control (SPC) software for long-term trend analysis of filter pressure drop and blower runtime.
Applications
- Pharmaceutical aseptic manufacturing suites (sterile filling lines, isolator support zones)
- Biotechnology R&D laboratories handling viral vectors or monoclonal antibodies
- Semiconductor front-end fabrication cleanrooms requiring Class 10/ISO 4 gowning protocols
- Medical device packaging cleanrooms certified to ISO 13485:2016
- Research institutions operating GLP-compliant analytical labs with controlled access zones
FAQ
What is the recommended maintenance frequency for the HEPA filter?
HEPA filters should be replaced every 12–18 months under continuous operation (24/7), or sooner if differential pressure exceeds 250 Pa—verified via built-in manometer or external gauge calibration.
Can the SS-AS-02 be retrofitted with a rigid door instead of the anti-static curtain?
Yes—custom rigid door kits (stainless steel or polycarbonate) are available as optional accessories, subject to structural reinforcement assessment and interlock revalidation.
Is the unit compliant with UL or CE safety standards?
The SS-AS-01/02 conforms to GB 4706.1-2005 (Chinese national standard equivalent to IEC 60335-1) and carries CCC certification; CE marking is available upon request for EU-market configurations meeting EN 61000-6-2/6-4 EMC and EN 60204-1 safety directives.
Does the control system support 21 CFR Part 11 electronic signature functionality?
The base configuration does not include electronic signatures; however, the optional HMI upgrade module provides role-based user authentication, audit trail export, and electronic approval workflows aligned with Part 11 Annex A requirements.
What is the maximum ambient temperature range for stable operation?
The unit is rated for continuous operation within 15–30 °C ambient temperature and ≤70% RH non-condensing, per IEC 60068-2-1/2 environmental test profiles.
