HLA-2000II & HLA-5000II Air Generators by Hailong

Overview

The HLA-2000II and HLA-5000II Air Generators are engineered for continuous, on-demand supply of high-purity compressed air in analytical laboratories and quality control environments. Unlike conventional oil-lubricated compressors or bottled gas systems, these units integrate a proprietary HL-A catalytic adsorption module to selectively remove hydrocarbons—including aliphatic and aromatic hydrocarbons, esters, and trace oil vapors—from ambient intake air. The purification process operates without consumable cartridges or scheduled regeneration cycles, enabling maintenance-free operation over extended service intervals. Air is drawn through an inlet particulate filter, compressed via a domestically manufactured oil-free scroll compressor, stored in a passivated stainless-steel reservoir with automatic condensate drainage, and delivered through electropolished, ultrasonically cleaned stainless-steel tubing. This architecture ensures consistent output stability, low noise emission (<55 dB(A)), and immunity to rust contamination—critical for GC carrier gas, FTIR purge lines, particle counters, and other instrumentation requiring inert, low-hydrocarbon airflow.

Key Features

• HL-A integrated catalytic adsorption system: Removes C1–C12 hydrocarbons, esters, and volatile organic compounds to <0.1 ppm (v/v), eliminating need for periodic filter replacement or manual regeneration.
• Passivated 316L stainless-steel air reservoir with fully automated electronic condensate ejection—prevents iron oxide carryover and ensures long-term corrosion resistance.
• Entire gas path constructed from electropolished, ultrasonically cleaned stainless-steel tubing (ISO 8502-3 compliant surface finish), minimizing particulate shedding and adsorptive memory effects.
• Oil-free scroll compressor with soft-start circuitry: Reduces mechanical stress during startup, extending operational lifespan beyond 15,000 hours under typical lab duty cycles.
• Compact benchtop footprint (460 × 290 × 380 mm) and acoustic enclosure design optimized for shared laboratory spaces; meets ISO 7779 noise emission standards.
• Dual-stage filtration and precision two-stage pressure regulation: Delivers stable output pressure (±0.01 MPa repeatability) across full flow range; includes thermal overload protection, pressure relief valve, and low-oil-level interlock (for compressor cooling).

Sample Compatibility & Compliance

These generators are validated for use with gas chromatography (GC) systems requiring ultra-low hydrocarbon carrier or makeup gas, including FID, ECD, and TCD detectors per ASTM D6299 and ISO 8573-1 Class 1.1.1 requirements. The <0.1 ppm hydrocarbon specification satisfies USP criteria for compressed air used in pharmaceutical environmental monitoring and complies with ISO 8573-1:2010 Class 1 (solid particles), Class 2 (water), and Class 1 (oil aerosol). Units operate within ambient conditions defined by IEC 61000-4-2 (ESD immunity) and meet CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61010-1). No external calibration gases or third-party certification is required for routine operation; however, optional traceable calibration reports per ISO/IEC 17025 are available upon request.

Software & Data Management

The HLA-II series operates as a standalone hardware platform without embedded firmware or network connectivity. All operational parameters—including real-time pressure, flow rate (via calibrated rotameter), compressor temperature, and accumulated runtime—are displayed on a front-panel LED interface. For integration into GLP/GMP workflows, analog 4–20 mA outputs are provided for remote pressure and flow monitoring, compatible with SCADA or LIMS data acquisition systems. Audit trails are maintained externally via facility logbooks or electronic batch records; the unit supports 21 CFR Part 11 compliance when paired with validated data capture software and user access controls implemented at the enterprise level.

Applications

• Carrier and auxiliary gas source for gas chromatographs (GC), especially flame ionization (FID) and electron capture (ECD) detectors where hydrocarbon background must be minimized.
• Purge gas for Fourier-transform infrared (FTIR) spectrometers and cavity ring-down spectroscopy (CRDS) systems requiring dry, hydrocarbon-free air.
• Supply air for cleanroom particle counters (ISO 14644-1 Class 5–8), laser diffraction particle analyzers, and mass spectrometer sample introduction systems.
• Instrument air for pneumatic actuators, valve manifolds, and automated sample handling platforms in regulated QC labs.
• Replacement for high-pressure cylinder banks in multi-instrument labs seeking reduced logistical overhead, elimination of gas cylinder changeovers, and improved safety profile.

FAQ

What is the maximum allowable inlet hydrocarbon concentration?
The system is rated for inlet air containing up to 100 ppm (v/v) total hydrocarbons. Exceeding this limit may reduce adsorption efficiency and require evaluation of upstream ventilation or pre-filtration.
Is dew point actively controlled or passively stabilized?
Dew point is managed passively via refrigerated air drying and stainless-steel reservoir thermal mass; output dew point ranges from 0 to 40 °C depending on ambient humidity and flow rate—consistent with ISO 8573-1 Class 2 specifications.
Can the unit be mounted vertically or installed in enclosed cabinets?
No. Units must be operated in upright position on a level, ventilated surface with ≥10 cm clearance on all sides to ensure adequate heat dissipation and compressor airflow.
Does the HL-A module require periodic replacement or regeneration?
No. The HL-A adsorbent is thermally and chemically stabilized for the lifetime of the unit under specified operating conditions; no scheduled servicing is required.
Are spare parts and technical documentation available internationally?
Yes. Hailong provides English-language operation manuals, schematic diagrams, and certified spare compressor modules with 12-month warranty; lead time for international shipment is 4–6 weeks.
