KHNA-500 Nitrogen-Air Generator

Brand : HK
Product origin : China
Delivery time : within 30 days after recieving full TT payment
Supply capacity : 100set/month

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.
