KHNA-500 Nitrogen-Air Generator

Overview

The KHNA-500 Nitrogen-Air Generator integrates two functions (nitrogen generation and air generation) into one unit. It features a compact design and simple operation, with built-in anti-liquid-overflow components, a water shortage reminder device, an automatic air drainage system, and impact-resistant, aging-resistant filters—ensuring safe and reliable operation.

It produces gas with high purity, stable pressure, and automatic flow rate tracking and display. Fully compatible with gas chromatographs produced by any domestic or international manufacturer, it is an ideal laboratory instrument to replace traditional gas cylinders.

It is widely used in sectors including petroleum, chemical engineering, pesticides, fertilizers, electric power, tobacco, pharmaceutical testing, wine making, water quality testing, environmental monitoring, indoor air monitoring, CDC (Centers for Disease Control and Prevention), colleges and universities, and research institutes.

Features

1. Gas generation starts with a switch; safe and reliable, equipped with overpressure and overheating protection devices.
2. Output flow rate can be automatically adjusted according to usage demand.
3. Equipped with overpressure protection and anti-liquid-overflow devices.
4. LED digital display.
5. Impact-resistant and aging-resistant filters.
6. High purity of generated gas, with no purity attenuation.
7. All gas paths adopt high-quality stainless steel.
8. One-time alkali addition; daily maintenance only requires refilling with distilled water.
9. Automatic drainage for the stainless steel gas storage tank system; all gas paths use high-quality stainless steel.
10. Good pressure stability, low noise, and strong purification capability.
11. Three-stage filtration system (oil-free).
12. Long service life, easy maintenance, and capable of 24/7 continuous operation.
13. Compatible with gas chromatographs of any model from any domestic or international manufacturer.
