Anyan AYAN-30L High-Flow Membrane Nitrogen Generator for Injection Molding & Packaging

Overview

The Anyan AYAN-30L High-Flow Membrane Nitrogen Generator is an engineered solution for continuous, on-site nitrogen supply in industrial packaging, injection molding, and laboratory inerting applications. It employs polymeric membrane separation technology—based on selective permeability differences between oxygen, water vapor, carbon dioxide, and nitrogen in compressed air—to produce nitrogen at a stable purity of 99% (v/v) with a nominal output flow of 30 L/min at pressures up to 0.6 MPa. Unlike pressure swing adsorption (PSA) systems, the AYAN-30L operates without cycling valves or consumable adsorbents, delivering immediate start-up (<3 minutes), minimal maintenance intervals, and long-term operational stability. Its integrated oil-free scroll compressor eliminates external air source dependency, while the suspended acoustic isolation system ensures ambient noise remains below 62 dB(A)—critical for integration into cleanrooms, packaging lines, or shared lab environments.

Key Features

• Imported Korean high-selectivity hollow-fiber membrane modules, offering >15,000 hours of service life under rated operating conditions and no periodic replacement of separation media
• Integrated three-stage pre-filtration system: coalescing filter (removes liquid water and oil aerosols), activated carbon adsorber (eliminates hydrocarbons and odors), and ultrafine particulate filter (<0.01 µm retention, ≤0.003 mg/m³ oil carryover)
• Digital nitrogen purity monitor with real-time LED display calibrated to ISO 8573-7 traceable standards, enabling verification of 99% N₂ output during operation
• Dual independent pressure regulation: one for membrane feed pressure control, another for user-side outlet pressure adjustment—ensuring consistent delivery across variable demand profiles
• Self-contained architecture with built-in air compression, cooling, drying, and filtration—no external dryer or aftercooler required
• Robust stainless-steel and powder-coated steel frame with IP20-rated electrical enclosure, suitable for indoor industrial environments with ambient temperatures from 5–40 °C and relative humidity ≤80% non-condensing

Sample Compatibility & Compliance

The AYAN-30L is designed for compatibility with nitrogen-requiring processes where 99% purity meets functional specifications—including food-grade modified atmosphere packaging (MAP), thermoplastic resin purging in injection molding machines, blanketing of solvent-based coatings, and inert gas overlay in analytical sample storage. It conforms to ISO 8573-1:2010 Class 2:2:2 for compressed air quality upstream of the membrane module, and its final nitrogen stream meets ISO 8573-7:2003 Class 2 for dew point (–40 °C) and particulate/oil content. While not certified to FDA 21 CFR Part 11 or GMP Annex 1 out-of-the-box, the unit supports audit-ready documentation packages (including IQ/OQ templates, calibration records, and maintenance logs) for regulated environments upon request. Optional upgrades include 4–20 mA analog output for purity/pressure telemetry and RS485 Modbus RTU interface for SCADA integration.

Software & Data Management

The AYAN-30L operates via a dedicated embedded microcontroller with local HMI interface—no PC software dependency. All operational parameters (feed pressure, outlet pressure, purity reading, runtime hours, filter service alerts) are logged internally with timestamped storage for ≥12 months. Data export is supported via USB port (CSV format) for offline analysis. For enterprise-level deployment, optional firmware enables remote monitoring through SNMP or MQTT protocols, allowing integration into centralized facility management systems. Audit trails comply with GLP-aligned record-keeping practices: all parameter changes, alarm events, and manual overrides are time-stamped and non-erasable.

Applications

• Food & beverage packaging: MAP gas blending for snack, dairy, and ready-meal lines requiring consistent 99% N₂ flow at 20–30 L/min
• Plastics processing: Purge gas for injection molding machines to prevent oxidation of heat-sensitive polymers (e.g., POM, PBT, PC)
• Electronics manufacturing: Inert atmosphere during solder paste reflow and component handling
• Laboratory use: Carrier gas for GC-TCD, blanketing for hygroscopic reagent storage, and inerting of gloveboxes
• Pharmaceutical secondary packaging: Nitrogen flushing of blister packs and vial stoppering lines

FAQ

What is the expected service life of the membrane module?
Under continuous operation at ≤0.6 MPa feed pressure and inlet air dew point ≤–20 °C, the Korean-sourced membrane has a rated service life of ≥15,000 operating hours before performance decay exceeds 10% of initial N₂ recovery rate.
Can this generator supply nitrogen directly to an injection molding machine’s purge system?
Yes—the AYAN-30L delivers stable 30 L/min at 0.4–0.6 MPa, matching typical OEM purge manifold requirements; a pressure regulator and particulate filter (ISO 8573-1 Class 2) are recommended upstream of the mold clamping unit.
Is external drying required before feeding air into the unit?
No—the integrated refrigerated dryer and coalescing filters maintain inlet air dew point ≤3 °C, satisfying membrane manufacturer specifications; however, ambient intake air must be free of liquid water and oil mist.
Does the unit support regulatory validation for pharmaceutical use?
While the base model is not pre-validated, Anyan provides full IQ/OQ documentation support, calibration certificates traceable to NIST standards, and change control logs—enabling qualification per ASTM E2500 and EU GMP Annex 15 guidelines.
How often do the pre-filters require replacement?
Under typical industrial conditions (ISO 8573-1 Class 4 intake air), the three-stage filter set requires replacement every 2,000–3,000 operating hours or annually—whichever occurs first—as indicated by differential pressure alarms on the HMI.
