Hailong HLA-2000II Air Generator

Overview

The Hailong HLA-2000II Air Generator is an engineered solution for laboratories requiring continuous, high-purity compressed air—specifically tailored for analytical instrumentation including gas chromatographs (GC), GC-MS systems, nitrogen generators, and flame-based detectors (e.g., FID, NPD). Unlike conventional oil-lubricated compressors or bottled air sources, this generator employs a multi-stage purification architecture grounded in catalytic hydrocarbon removal and precision pressure stabilization. Ambient air is drawn through an integrated HL-A adsorption module containing proprietary activated carbon and metal oxide catalysts, which selectively oxidize and retain volatile organic compounds—including aliphatic and aromatic hydrocarbons, esters, and trace oils—to sub-ppm levels (<0.1 ppm total hydrocarbons). The purified air is then stored in an electropolished stainless-steel reservoir equipped with automatic condensate drainage, eliminating rust contamination and ensuring long-term system integrity. Designed for zero-maintenance operation under standard lab conditions (0–40 °C, <85% RH), the unit delivers stable output across its full flow range (0–2000 mL/min) and pressure envelope (0–0.5 MPa), with factory calibration set at 0.4 MPa to match typical detector inlet requirements.

Key Features

• Electropolished stainless-steel fluid path throughout—ultrasonically cleaned per ISO 10993-compliant protocols to prevent particulate shedding and surface corrosion
• Dual-stage filtration system: pre-filter + catalytic HL-A adsorption module ensures consistent hydrocarbon removal even with variable inlet air quality (max input: <100 ppm HC)
• Two-stage pressure regulation with mechanical feedback loop—maintains ±0.01 MPa pressure stability under dynamic flow demand
• Low-voltage soft-start compressor control—reduces inrush current and extends service life of rotary vane compression elements
• Integrated auto-drain stainless-steel storage tank (3.2 L capacity)—prevents moisture accumulation and eliminates manual draining or yellow rust contamination
• Compact footprint (450 × 260 × 365 mm) and acoustic enclosure design—operates at <52 dB(A), suitable for benchtop placement in shared analytical labs

Sample Compatibility & Compliance

The HLA-2000II is compatible with all major GC and GC-MS platforms requiring clean, dry, oil-free air as a carrier, make-up, or combustion gas. Its certified output purity meets ASTM D6216 Class I specifications for instrumental air and aligns with ISO 8573-1:2010 Class 1.2.1 (solid particles, water, oil aerosol). While not intrinsically rated for hazardous locations, it complies with IEC 61010-1 safety standards for laboratory electrical equipment. All internal wetted materials are non-reactive and non-outgassing—validated for use in GLP and GMP environments where auditability of gas source qualification is required. No regulatory certification (e.g., FDA 21 CFR Part 11) applies directly to air generators; however, the unit supports compliant workflows when paired with validated instrument software and documented operational procedures.

Software & Data Management

The HLA-2000II operates as a standalone analog-controlled device with no embedded firmware or digital interface. Status indicators include LED-lit pressure gauge, flow meter, and power-on lamp. For integration into networked lab infrastructure, optional analog-to-digital signal adapters (0–10 V or 4–20 mA) can be installed to feed real-time pressure and flow data into SCADA or LIMS platforms. All operational parameters—including runtime hours, maintenance intervals, and pressure deviation logs—are intended to be recorded manually per internal SOPs. The absence of onboard memory or user-accessible configuration menus ensures deterministic behavior and simplifies IQ/OQ validation protocols.

Applications

• Flame Ionization Detector (FID) and Flame Photometric Detector (FPD) air supply in gas chromatography
• Make-up gas for electron capture detectors (ECD) and thermal conductivity detectors (TCD)
• Carrier gas auxiliary stream in multidimensional GC systems
• Air source for nitrogen generator feed-air pre-treatment
• Controlled atmosphere generation in environmental simulation chambers
• Calibration gas blending systems requiring ultra-low-hydrocarbon background air

FAQ

What is the expected service life of the HL-A adsorption module?
Under typical lab conditions (20–25 °C, <60% RH, ambient hydrocarbon load <10 ppm), the HL-A module maintains performance for ≥12 months before replacement. Lifetime decreases proportionally with elevated inlet hydrocarbon concentration or humidity.
Can the output pressure be adjusted beyond the factory setting of 0.4 MPa?
Yes—the second-stage regulator is manually adjustable up to 0.5 MPa. However, sustained operation above 0.4 MPa may reduce long-term filter efficiency and is not recommended unless validated for specific instrument requirements.
Is the unit suitable for cleanroom environments (ISO Class 5 or better)?
While the output air meets ISO 8573-1:2010 Class 1.2.1, the generator itself is not ISO 14644-certified for particle emission. It must be located outside the cleanroom, with purified air delivered via stainless-steel tubing and point-of-use filtration.
Does the auto-drain function require periodic maintenance?
No—the float-actuated solenoid valve is self-cleaning and requires no scheduled servicing. Condensate discharge occurs only when liquid level exceeds threshold, minimizing compressed air loss.
What certifications does the HLA-2000II hold?
It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to RoHS 2011/65/EU. No UL, CSA, or ATEX certification is provided.
