Haolong HLA-02 Oil-Free Large-Capacity Laboratory Air Compressor

Overview

The Haolong HLA-02 is an oil-free, large-capacity laboratory air compressor engineered for continuous, low-maintenance operation in analytical, clinical, and research environments where clean, dry, and hydrocarbon-free compressed air is critical. Unlike lubricated compressors, the HLA-02 employs a maintenance-free, PTFE-coated diaphragm or scroll mechanism—eliminating oil carryover and ensuring ISO 8573-1 Class 1.2.1-compliant air quality (solid particles ≤0.1 µm, dew point ≤−20 °C, oil content <0.01 mg/m³). Its integrated desiccant-assisted drying system and multi-stage particulate filtration (including inlet silencing filter and coalescing post-filter) deliver stable, contamination-free airflow essential for gas chromatography (GC), FTIR purge systems, particle counters, pneumatic actuators, and mass spectrometry auxiliary gas supply. The unit operates within standard laboratory ambient conditions (0–40 °C) and features a robust 23 L ASME-styled receiver tank that dampens pressure pulsation and supports demand-based load cycling.

Key Features

• Oil-free compression technology ensures zero hydrocarbon contamination—critical for GC carrier gas, FTIR background purging, and cleanroom instrumentation.
• Integrated low-noise design: inlet acoustic filter + vibration-damping HAJ-01 mount reduces operational noise to ≤45 dB(A), meeting ISO 7779 requirements for quiet lab environments.
• Precision pressure regulation with analog gauge and fine-tuning valve enables stable output across 0.1–0.6 MPa; pressure stability maintained within ±0.02 MPa under variable flow loads.
• Automatic condensate drainage system prevents moisture accumulation in the receiver tank—minimizing corrosion risk and maintaining consistent dew point performance.
• Soft-start circuitry reduces inrush current during startup, extending motor winding life and improving compatibility with shared lab circuits.
• Over-pressure safety cutoff (mechanical + electronic dual redundancy) activates at 0.7 MPa, complying with EN 61000-6-2 EMC and EN 60335-1 general safety standards.

Sample Compatibility & Compliance

The HLA-02 delivers instrument-grade air compatible with gas-consuming analytical platforms requiring ISO 8573-1 Class 1–3 air purity, including but not limited to: Shimadzu GC-2030, Thermo Fisher ISQ EC, PerkinElmer Clarus SQ 8, Agilent 8890 GC systems, and Mettler Toledo moisture analyzers. It meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage directive (EN 62368-1). While not certified to FDA 21 CFR Part 11 out-of-the-box, its pressure/flow logs (when interfaced via optional RS-485 module) support GLP/GMP traceability when integrated into validated lab networks. All wetted materials—including stainless steel check valves, aluminum receiver tank, and food-grade elastomer seals—comply with USP <661.1> material biocompatibility guidelines.

Software & Data Management

The HLA-02 operates as a standalone analog-controlled system with no embedded firmware or touchscreen interface. For integration into centralized lab infrastructure, an optional RS-485 communication module (sold separately) enables Modbus RTU protocol connectivity. This allows remote monitoring of real-time pressure, runtime hours, and fault codes (e.g., over-temperature, drain timeout) via LabVIEW, Ignition SCADA, or custom Python-based dashboards. Audit trails—including timestamped pressure setpoint changes and manual drain events—can be exported in CSV format for internal QA review. No cloud dependency or proprietary software is required; configuration remains fully local and IT-administrator controllable.

Applications

• Carrier and make-up gas supply for capillary GC systems requiring ≥99.999% hydrocarbon-free air.
• Pneumatic sample introduction in ICP-MS and laser ablation systems where particulate and oil vapor interference must be eliminated.
• Actuation and control air for automated liquid handlers, robotic arms, and high-precision valve manifolds.
• Dry-air purge for optical benches, interferometers, and environmental test chambers demanding dew point stability below −20 °C.
• Primary air source for multi-station labs supporting concurrent use by up to four mid-flow instruments (e.g., two GCs + one FTIR + one particle counter) without pressure drop.

FAQ

Is the HLA-02 suitable for use with mass spectrometry systems requiring ultra-high-purity air?
Yes—provided the optional inline activated carbon + molecular sieve filter kit is installed, the HLA-02 achieves total hydrocarbon levels <0.5 ppb and dew point ≤−40 °C, satisfying ASTM D6304 and ISO 8573-1:2010 Class 1.1.1 specifications.
Can the unit be mounted in a ventilated cabinet or enclosed equipment rack?
Yes, but minimum 100 mm clearance on all sides and unobstructed top exhaust are mandatory to maintain thermal management; ambient temperature must remain ≤35 °C at intake grille.
Does the automatic drain require periodic maintenance or consumables?
The float-actuated solenoid drain includes a replaceable 5-µm sintered bronze filter element (part #HLA-DRN-FIL); recommended replacement interval is every 6 months under continuous operation.
What electrical protection is built into the power supply?
The unit incorporates a Type II MOV surge suppressor, thermal cutout at 120 °C motor winding temperature, and a 3 A slow-blow fuse compliant with IEC 60127-2.
Is technical documentation available in English with full schematics and service manuals?
Yes—English-language operator manuals, wiring diagrams, and spare parts catalogs (including OEM compressor head part numbers) are provided upon request to registered institutional purchasers.
