Overview
The Anyan AYAN-30LG is a compact, integrated membrane-based nitrogen generator engineered specifically for continuous, on-site nitrogen supply in food packaging, modified atmosphere packaging (MAP), and laboratory inerting applications. It employs polymeric hollow-fiber membrane technology—originally developed for industrial gas separation—to selectively permeate oxygen, water vapor, and carbon dioxide from compressed air, while retaining nitrogen with high selectivity. Unlike pressure swing adsorption (PSA) systems, the AYAN-30LG operates without molecular sieves, valves, or cycling mechanisms, delivering stable nitrogen output within ≤3 minutes of startup. Its design prioritizes operational reliability, low maintenance burden, and compliance-ready performance in environments where consistent gas quality and minimal downtime are critical—such as ISO 22000-certified food processing facilities or GLP-aligned analytical labs requiring inert purge gas.
Key Features
- Imported Korean polymeric membrane modules with proven long-term stability and >15,000-hour service life under nominal operating conditions
- Integrated oil-free scroll air compressor with suspended acoustic isolation housing, achieving noise levels ≤62 dB(A) at 1 m distance
- Three-stage pre-filtration system: coalescing filter (0.01 µm particulate retention), activated carbon adsorber (oil vapor removal), and desiccant-based water separator (dew point ≤ −40 °C)
- Digital nitrogen purity monitor with real-time LED display (0–100% N₂, resolution ±0.1%), calibrated per ISO 8573-1 Class 2:2:2 for compressed air quality verification
- Dual independent pressure regulation: upstream (compressor discharge) and downstream (nitrogen outlet), enabling precise control across variable demand profiles
- No consumables required beyond periodic filter element replacement (recommended every 6,000 operating hours or annually, whichever occurs first)
Sample Compatibility & Compliance
The AYAN-30LG is validated for use with food-grade packaging lines compliant with FDA 21 CFR Part 110 and EC No. 1935/2004. Its nitrogen output meets ISO 8573-1:2010 Class 2 (solid particles), Class 2 (water), and Class 2 (oil) specifications when operated within specified inlet air quality limits (ISO 8573-1 Class 4 or better). The unit carries CE marking per Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. All wetted materials—including stainless steel manifolds, fluoropolymer-coated membranes, and food-grade elastomers—are certified to FDA 21 CFR §177.2600 and EU Regulation (EC) No. 1935/2004 for indirect food contact.
Software & Data Management
While the AYAN-30LG operates as a standalone analog-controlled unit, it supports optional RS-485 Modbus RTU interface for integration into facility SCADA or MES platforms. Digital outputs include real-time purity (%N₂), outlet pressure (MPa), and cumulative runtime (hours)—all accessible via external PLC or HMI. Audit trail functionality is enabled when connected to a compliant data acquisition system meeting FDA 21 CFR Part 11 requirements for electronic records and signatures. Internal logging (via optional SD card module) captures timestamped purity and pressure events at user-defined intervals (1 min to 24 h), supporting routine QA review and preventive maintenance scheduling.
Applications
- Modified Atmosphere Packaging (MAP) of fresh produce, baked goods, snacks, and dairy products
- Inert blanketing of storage tanks, mixing vessels, and filling heads in food & beverage production
- Carrier and purge gas for GC-TCD/FID analysis, headspace sampling, and solvent evaporation systems
- Blanket gas for pharmaceutical lyophilization and API handling under GMP Annex 1 conditions
- Lab-scale nitrogen supply for glove boxes, anaerobic chambers, and electron microscopy sample preparation
FAQ
What is the expected lifetime of the membrane module under continuous operation?
Typical service life exceeds 15,000 hours when inlet air meets ISO 8573-1 Class 4 specifications and pre-filters are replaced per schedule.
Does the unit require external cooling or ventilation?
Yes—minimum ambient airflow of 200 m³/h is recommended; installation in enclosed cabinets requires forced-air exhaust ducting.
Can output purity be adjusted to lower levels (e.g., 95% N₂) for cost-sensitive applications?
No—purity is fixed by membrane selectivity and operating pressure; however, flow rate can be throttled to extend membrane life in partial-load scenarios.
Is validation documentation (IQ/OQ/PQ protocols) available?
Standard factory test reports (including flow, purity, and pressure verification) are provided; customized IQ/OQ packages are available upon request.
What maintenance intervals are recommended for the three-stage filtration system?
Coalescing and activated carbon filters: replace every 6,000 operating hours or annually; desiccant cartridge: replace every 12 months or after 8,000 hours, whichever occurs first.
