Overview
The AYAN-ZA10L Zero-Air Generator is an engineered solution for laboratories and industrial facilities requiring continuous, high-purity compressed air with ultra-low hydrocarbon contamination. It operates on a robust oil-free compression principle—eliminating the risk of lubricant carryover—and integrates a dual-stage purification architecture: first, a high-efficiency coalescing filter removes particulates and aerosols; second, a heated catalytic converter and activated carbon adsorption column reduce total hydrocarbons to < 0.1 ppm (as methane-equivalent, verified by flame ionization detection). The system delivers stable output pressure (0–0.5 MPa) and adjustable flow (0–10 L/min), with dew point control spanning −40 °C to +40 °C, achieved via a thermally regulated desiccant drying chamber and precision pressure-regulated exhaust. Designed for uninterrupted operation in ambient environments between 5 °C and 40 °C (RH < 85%, low-dust), it meets baseline operational requirements for GC-FID carrier gas, FTIR purge air, environmental monitoring calibrations, and cleanroom support systems.
Key Features
- Oil-free diaphragm compressor ensures zero lubricant contamination—critical for trace-level analytical applications.
- Dual-stage filtration: 0.01 µm coalescing pre-filter + catalytic oxidation + high-capacity activated carbon bed for consistent < 0.1 ppm THC removal.
- Integrated dew point management: adjustable desiccant dryer with thermal stabilization maintains specified moisture levels across variable ambient conditions.
- Real-time pressure regulation via precision stainless-steel pressure-reducing valve and digital pressure transducer (0.01 MPa resolution).
- Front-panel LED indicators for power status, compressor operation, and system fault alerts (e.g., filter saturation, thermal overload).
- Modular service design: all consumables—including activated carbon cartridges and desiccant media—are user-replaceable without tools; recommended replacement interval: every 1,000 operating hours per ISO 8573-1 Class 1:2:1 compliance protocol.
Sample Compatibility & Compliance
The AYAN-ZA10L is compatible with ambient air intake under ISO 8573-1 Class 4 (particulate) and Class 5 (moisture) conditions. Its purified output satisfies ASTM D6216 (for GC carrier gas), USP (compressed air quality for pharmaceutical manufacturing), and ISO 8573-1:2010 Class 1:2:1 (hydrocarbons, particles, water). While not certified to FDA 21 CFR Part 11 out-of-the-box, its pressure and flow stability support GLP/GMP-compliant audit trails when paired with external data loggers. No internal software or electronic signatures are implemented—consistent with Class II laboratory utility equipment classification per IEC 61010-1.
Software & Data Management
The AYAN-ZA10L operates as a standalone hardware system with no embedded firmware, network interface, or proprietary software. All operational parameters are monitored via analog sensors and displayed through discrete LED indicators. For integration into automated lab environments, optional 4–20 mA analog outputs (pressure, flow) and dry-contact relay signals (compressor status, thermal fault) are available upon request—enabling connection to SCADA, LIMS, or PLC-based facility monitoring systems. No configuration files, firmware updates, or cybersecurity protocols apply, minimizing validation burden in regulated settings.
Applications
- Gas chromatography (GC-FID, GC-ECD): as zero-air source for detector makeup gas and combustion air.
- Environmental air monitoring stations: calibration gas generation for ozone analyzers, NOₓ chemiluminescence detectors, and VOC samplers.
- Power industry maintenance: drying and purging of transformer insulation oil systems and hydrogen-cooled turbine generators.
- Electronics manufacturing: controlled atmosphere for solder paste reflow ovens and conformal coating lines.
- Pharmaceutical packaging: inerting and blanketing of blister packaging lines where residual hydrocarbons must be minimized per ICH Q5C guidelines.
- Research labs: stable air supply for FTIR spectrometers, particle counters, and aerosol generation systems requiring repeatable background composition.
FAQ
What is the recommended maintenance schedule for the AYAN-ZA10L?
Activated carbon cartridges and desiccant media require replacement every 1,000 operating hours (approximately 42 days of continuous use) to maintain hydrocarbon and moisture specifications per ISO 8573-1.
Can the unit operate continuously at maximum flow (10 L/min) and pressure (0.5 MPa)?
Yes—rated for 100% duty cycle at full load when ambient temperature remains ≤35 °C and ventilation clearance ≥10 cm on all sides.
Is the output air suitable for use in medical device testing per ISO 8573-1?
Output meets ISO 8573-1:2010 Class 1:2:1 for hydrocarbons and particles; however, end-user validation per ISO 10993-12 is required for biocompatibility-critical applications.
Does the generator include pressure relief protection?
Yes—a certified 0.8 MPa mechanical pressure relief valve is installed upstream of the final regulator, compliant with PED 2014/68/EU Annex I essential safety requirements.
How is hydrocarbon performance verified post-installation?
Users may validate THC content using a calibrated FID analyzer per EPA Method TO-15 or ASTM D6216; AYAN provides a certificate of conformance with initial factory test data (FID response < 0.05 ppm C₁–C₄ at 5 L/min, 0.3 MPa).
