Overview
The AIRTECH SJAT Series Automatic-Door Air Shower is an engineered personnel decontamination system designed for controlled environments including ISO Class 5–8 cleanrooms, pharmaceutical manufacturing suites, semiconductor fabrication facilities, and biotechnology laboratories. It operates on the principle of high-velocity laminar airflow—generated by integrated centrifugal blowers—to remove particulate contamination from personnel garments and surfaces before entry into critical zones. The system employs a dual-stage filtration architecture: a pre-filter (G4 class) captures coarse particles, followed by a terminal HEPA filter (H14 grade per EN 1822) with certified efficiency ≥99.99% at 0.3 µm—the industry-standard challenge particle size for cleanroom air shower validation. The automatic sliding door mechanism, actuated via infrared or motion-sensing interlock, ensures seamless integration with facility access control systems while maintaining pressure differentials across cleanroom boundaries.
Key Features
- Ultra-slim cabinet design with recessed blower modules maximizes floor space utilization without compromising airflow integrity or structural rigidity.
- 16 independently adjustable, 360° rotatable stainless-steel nozzles enable precise directional targeting of high-velocity air (≥25 m/s) across shoulders, torso, and lower limbs—optimized for human ergonomics and particle dislodgement efficacy.
- Multi-programmable logic controller (PLC) supports configurable cycle parameters: blow time (5–99 s), delay intervals, door sequencing, and interlocked lighting/alarms—enabling alignment with site-specific SOPs and regulatory workflows.
- Intuitive 7-inch color HMI touchscreen provides real-time visualization of operational status—including filter differential pressure, door position, blower RPM, and fault diagnostics—with bilingual (English/Chinese) interface support.
- Modular construction using standardized flanged panels and plug-and-play electrical harnesses reduces on-site commissioning time by up to 40% and simplifies component-level maintenance under ISO 14644-3 compliance protocols.
Sample Compatibility & Compliance
The SJAT Series accommodates standard operator profiles (height range: 1.5–2.0 m; shoulder width ≤600 mm) and integrates seamlessly with cleanroom gowning protocols requiring full-body coverage (e.g., bunny suits, hoods, boot covers). All materials in contact with airflow—including nozzles, inner lining, and door seals—meet USP <88> Class VI biocompatibility requirements and are non-shedding per ISO 14644-1 Annex B. The unit complies with IEC 60335-1 (safety of electrical appliances), EN 61000-6-3 (EMC emissions), and EN 61000-6-2 (immunity). Optional validation packages include IQ/OQ documentation aligned with EU GMP Annex 1 and FDA 21 CFR Part 11 data integrity expectations.
Software & Data Management
Embedded firmware supports audit-trail-enabled operation logging (timestamped events: door open/close, cycle start/end, alarm triggers, filter replacement alerts) stored locally for ≥12 months. Optional Ethernet/IP or Modbus TCP connectivity enables integration with centralized MES or SCADA platforms for remote monitoring and automated reporting. Data export formats include CSV and PDF; all logs retain cryptographic hash integrity verification to satisfy GLP/GMP record retention mandates.
Applications
- Pharmaceutical aseptic processing areas requiring personnel ingress control prior to Grade A/B zones.
- Medical device assembly cleanrooms governed by ISO 13485 and FDA QSR 21 CFR Part 820.
- Microelectronics wafer handling environments where sub-micron particle exclusion is critical to yield assurance.
- Vaccine and cell therapy manufacturing suites operating under cGMP conditions with strict environmental monitoring requirements.
- Research institutions conducting nanomaterial handling or sterile tissue culture work requiring validated particulate mitigation.
FAQ
What filter certification standards does the HEPA module meet?
The terminal filter is tested and certified to EN 1822-1:2019 (H14 class), with independent test reports available upon request verifying ≥99.99% efficiency at 0.3 µm MPPS.
Can the air shower be integrated with existing cleanroom access control systems?
Yes—dry-contact relay outputs and optional RS-485/Modbus RTU support interoperability with third-party door controllers, badge readers, and BMS platforms.
Is validation support provided for GMP-compliant installations?
AIRTECH offers optional IQ/OQ protocol templates, traceable calibration certificates for airflow sensors, and on-site commissioning assistance by qualified field engineers.
What is the expected service life of the HEPA filter under typical usage?
Filter lifetime depends on ambient particle load and usage frequency; average replacement interval is 12–18 months when monitored via differential pressure sensors and logged in the HMI.
Does the unit comply with energy efficiency regulations for industrial equipment?
Yes—the blower motors meet IE3 efficiency class per IEC 60034-30-1, and the control system implements adaptive fan speed modulation to reduce power consumption during standby mode.
