HJ Y09-010 Ultra-Pure Water-Based Aerosol Generator

Overview

The HJ Y09-010 Ultra-Pure Water-Based Aerosol Generator is an engineered solution for non-intrusive, residue-free airflow visualization in controlled environments. Unlike glycol- or oil-based foggers, this device utilizes precisely controlled resistive heating of deionized or low-conductivity water to generate a stable, monodisperse-like aerosol plume composed exclusively of condensed water droplets. Its operating principle relies on thermally induced phase transition—water is heated to saturation under regulated pressure and flow conditions, then rapidly expanded into ambient air to induce nucleation and condensation. The resulting aerosol exhibits high optical contrast against typical cleanroom lighting while leaving no chemical residue, particulate deposit, or volatile organic compound (VOC) trace—critical for ISO 14644-3 compliant airflow pattern qualification and GMP Annex 1 validation protocols.

Key Features

• Residue-free operation: Generates aerosol solely from purified water—no surfactants, propellants, or carrier solvents; fully compatible with ISO 14644-1 Class 1–10,000 cleanrooms and USP <797>/<800> pharmaceutical compounding suites.
• Sustained output capability: Delivers continuous, stable aerosol generation for ≥50 minutes per fill cycle under optimal water level (28 mm) and conductivity (0.15–1.00 mS/cm) conditions.
• Controlled droplet sizing: Engineered nozzle and thermal regulation ensure ≥80% mass distribution within the 1–10 µm aerodynamic diameter range—ideal for visualizing laminar and transitional flow regimes without gravitational settling artifacts.
• Flexible deployment: Integrated port supports optional 2-meter flexible smoke tube for linear or curtain-style plume delivery—enabling directional testing of HEPA filter integrity, transfer hatches, and pass-through interlocks.
• Low acoustic signature: Acoustic emission ≤52 dB(A) at 1 meter distance—minimizes interference during real-time particle imaging and video capture in noise-sensitive QA/QC labs.
• Robust industrial architecture: Stainless-steel and PTFE-wetted components; IP20-rated enclosure; DC 45 V isolated heater circuitry for electrical safety in humid environments.

Sample Compatibility & Compliance

The Y09-010 is validated for use with water having conductivity between 0.15 and 1.00 mS/cm—ensuring compatibility with standard laboratory-grade deionized water systems (e.g., Milli-Q®, ELGA Purelab). It does not require compressed air, nitrogen, or external gas supply, eliminating cross-contamination risks associated with zero-air generators. The device meets mechanical and electrical safety requirements per GB 4793.1–2019 (equivalent to IEC 61010-1) and is routinely deployed in facilities undergoing FDA pre-approval inspections, EU GMP Annex 1 audits, and ISO 14644-3 certification. Its residue-free output satisfies stringent residue limits defined in ISO 14644-8 (Chemical Contamination) and supports GLP-compliant documentation of airflow behavior.

Software & Data Management

The Y09-010 operates as a standalone hardware instrument with no embedded microcontroller or digital interface. All operational parameters—including fill volume, water conductivity, ambient temperature, and run duration—are manually recorded per SOP-defined log sheets. For integration into electronic quality management systems (eQMS), users may pair the generator with time-synchronized high-speed cameras (e.g., Phantom v2512) and third-party particle tracking software (e.g., DaVis, MATLAB PIVToolbox) for quantitative velocity vector mapping. While the unit itself does not support FDA 21 CFR Part 11-compliant audit trails, its deterministic physical output enables full traceability when used within documented test protocols referencing ISO/TR 14644-12 and IEST-RP-CC006.3.

Applications

• ISO 14644-3 Annex B.3 airflow pattern verification in unidirectional and non-unidirectional cleanrooms.
• GMP Annex 1 Section 4.38–4.42 evaluation of air change rates, recovery times, and containment performance.
• HEPA/ULPA filter leak testing via downstream scanning with light-scatter detection.
• Pressure differential validation across anterooms, airlocks, and isolators.
• Exhaust duct and fume hood face velocity uniformity assessment per ANSI/ASHRAE 110.
• Personnel gowning procedure efficacy testing through dynamic airflow disruption analysis.

FAQ

What water quality specifications are required for reliable operation?
Deionized water with conductivity between 0.15 and 1.00 mS/cm is mandatory. Conductivity outside this range may cause inconsistent雾化, premature scaling, or heater element degradation.
Can the Y09-010 be used in sterile manufacturing areas without compromising classification?
Yes—provided water is sourced from a validated, endotoxin-free DI system and the generator is surface-decontaminated prior to entry per facility SOP. No viable microorganisms or pyrogens are introduced during雾化.
Is calibration or periodic verification required?
No formal calibration is specified; however, daily functional verification using a calibrated conductivity meter and timed volumetric output check (≥5500 mL/h) is recommended per ISO/IEC 17025-aligned internal procedures.
Does the unit comply with explosion-proof or hazardous location standards?
No—it is rated for general-purpose indoor use only (IEC 60529 IP20) and must not be operated in flammable vapor or dust-laden atmospheres.
How is maintenance performed?
Monthly descaling with 5% citric acid solution is advised. Heater cartridge replacement interval is 12 months under continuous daily use, or after 500 operational hours—whichever occurs first.
