FUXIA FLB-1A Single-Person Dual-Side Air Shower

Overview

The FUXIA FLB-1A Single-Person Dual-Side Air Shower is an engineered entry-level personnel air shower system designed for controlled environment facilities requiring reliable particle removal at the interface between non-classified and classified zones. It operates on the principle of high-velocity laminar airflow generated by a centrifugal blower, directing filtered air through adjustable stainless-steel nozzles positioned on both left and right sides of the chamber. This dual-side configuration ensures comprehensive surface decontamination of operators’ garments, headgear, and footwear—critical for maintaining ISO Class 5–8 cleanroom integrity. The unit integrates a two-stage filtration architecture: a pre-filter captures coarse particulates (e.g., lint, hair), while dual HEPA filters (600 × 600 × 120 mm each, rated at ≥99.99% efficiency for ≥0.5 µm particles per sodium flame test) deliver certified clean air. Its structural design complies with fundamental cleanroom interface requirements defined in ISO 14644-1 and supports GMP-aligned facility workflows where personnel ingress must be validated and repeatable.

Key Features

• Dual-side nozzle array (12 total, Φ30 mm stainless steel) enables symmetrical, high-velocity (20–28 m/s) air impingement across the full frontal and lateral surface area of a standing operator.
• Programmable air shower cycle (0–99 seconds) with real-time digital display and audible end-of-cycle signal for operator awareness and process standardization.
• Photoelectric sensor-controlled interlocked door system prevents simultaneous opening of entry and exit doors, eliminating unfiltered air bypass and ensuring strict airlock functionality.
• Modular construction using electrogalvanized steel frame with powder-coated finish; compatible with standard cleanroom wall interfaces and ceiling grid systems.
• Energy-optimized 550 W motor assembly with thermal overload protection and low-noise operation (<65 dB[A] at 1 m), supporting continuous-duty deployment in 24/7 production environments.
• Front-accessible filter housing allows routine HEPA and pre-filter replacement without tools or chamber disassembly—reducing maintenance downtime and technician training burden.

Sample Compatibility & Compliance

The FLB-1A is intended exclusively for personnel decontamination—not material or equipment pass-through—and is validated for use with standard cleanroom garments (e.g., bouffant caps, coveralls, shoe covers) compliant with IEST-RP-CC003.3. It meets mechanical safety requirements per EN 60335-1 and electrical safety per GB 4706.1 (China National Standard equivalent to IEC 60335-1). While not intrinsically certified for hazardous locations, its non-sparking motor and grounded chassis support installation in general-purpose pharmaceutical, biotech, and medical device manufacturing cleanrooms operating under ISO 13485 and FDA 21 CFR Part 820 quality systems. Documentation includes factory-verified airflow velocity reports, filter certification data sheets, and door interlock functional test records—all retained as part of facility qualification (IQ/OQ) packages.

Software & Data Management

The FLB-1A operates via embedded microcontroller logic with no external software dependency. Cycle duration, door status, and fault codes (e.g., filter clogging alert, motor overtemperature) are indicated via LED interface. For regulated environments, optional RS-485 Modbus RTU output enables integration into building management systems (BMS) or MES platforms for audit-trail logging of usage frequency, cycle timestamps, and door event history—supporting 21 CFR Part 11-compliant electronic record retention when paired with validated data acquisition servers. All firmware revisions are version-logged and traceable to manufacturing batch numbers.

Applications

• Pharmaceutical aseptic processing suites (Grade A/B buffer zones)
• Medical device assembly cleanrooms (ISO 13485-certified facilities)
• Biotechnology R&D laboratories handling cell culture or viral vectors
• Microelectronics fabrication front-end areas requiring sub-micron particle control
• Food-grade packaging lines governed by SQF or BRCGS hygiene protocols
• Academic core facilities managing shared cleanroom access for nanomaterial synthesis

FAQ

What is the recommended maintenance schedule for the FLB-1A?

Pre-filters should be inspected weekly and replaced every 3–6 months depending on ambient particulate load; HEPA filters require annual integrity testing (DOP/PAO scan) and replacement every 2–5 years based on upstream pressure differential trends.
Can the FLB-1A be integrated with existing cleanroom monitoring systems?

Yes—via optional RS-485 Modbus RTU interface, enabling real-time status telemetry and event logging compatible with Siemens Desigo, Honeywell Experion, or custom SCADA architectures.
Is the unit suitable for ISO Class 4 (Class 10) environments?

No—the FLB-1A is designed for personnel ingress into ISO Class 5–8 zones; it does not generate unidirectional airflow or meet the ultra-low particle concentration thresholds required downstream of Grade A laminar flow hoods.
Does the dual-side configuration require additional floor space compared to single-side units?

Yes—the external width increases to 1300 mm to accommodate lateral nozzle banks and structural reinforcement, but footprint depth remains unchanged at 760 mm for retrofit compatibility.
Are replacement HEPA filters supplied with test certificates?

All factory-supplied HEPA filters include individual sodium flame test reports, serial-numbered filter media certifications, and leak-test validation documentation per IEST-RP-CC001.3.
