NA-300C Nitrogen and Air Generator

Product Introduction
The NA-300C Nitrogen and Air Generator is a laboratory gas supply system designed to provide nitrogen and air for gas chromatography (GC) instruments. It integrates gas generation, pressure control, filtration, and automatic drainage in one compact unit, offering a convenient alternative to conventional gas cylinders for compatible laboratory applications.
With nitrogen purity of up to 99.999%, automatic output-flow adjustment, stainless steel gas paths, and three-stage oil-free filtration, the NA-300C supports stable gas supply for routine analytical testing. Its digital LED display, built-in protection functions, and easy-maintenance design make it suitable for continuous laboratory operation.

Performance Features
• High-Purity Nitrogen: Nitrogen purity up to 99.999%, with oxygen content below 3 ppm and a dew point of −56°C, as specified.
• Combined Nitrogen and Air Supply: Provides nitrogen output up to 300 mL/min and air output up to 2000 mL/min.
• Automatic Flow Adjustment: Output flow adjusts according to gas consumption.
• LED Digital Display: Displays operating information for convenient monitoring.
• Stainless Steel Gas Paths: High-quality stainless steel gas circuits support corrosion resistance and stable gas delivery.
• Three-Stage Oil-Free Filtration: Helps remove contaminants from the output gas.
• Automatic Drainage: The stainless steel storage tank features automatic drainage.
• Built-In Protection: Includes overpressure, overheating, and liquid carryover protection.
• Stable Pressure and Low Noise: Designed for steady gas supply and low-noise operation.
• Easy Maintenance: Alkali is added initially; routine maintenance mainly requires replenishing distilled or deionized water as needed.
• Continuous Operation: Designed for 24-hour continuous use.
• Broad GC Compatibility: Suitable for connection to compatible gas chromatographs from different manufacturers, subject to their gas-flow, pressure, and purity requirements.

Working Principle
The NA-300C generates nitrogen and air through its internal gas-generation and purification systems. Generated gas passes through the internal gas paths and filtration stages before being delivered to the connected analytical instrument.
The nitrogen system uses a water-based electrolyte arrangement, with the required alkaline solution added initially and water replenished during routine maintenance. Internal pressure and protection controls help maintain safe operation, while the air-generation and purification system supplies filtered air. Flow output adjusts according to demand, and the automatic drainage system helps remove accumulated liquid from the storage tank.
