Oxygen Free Nitrogen (OFN) is a high-purity, inert gas widely used across the industrial, refrigeration, and manufacturing sectors. Its clean, dry, and non-reactive properties make it ideal for applications that require a stable, contaminant-free atmosphere.
In the refrigeration and air-conditioning industry, OFN is used for pressure testing, purging, and leak detection, ensuring systems are clean, dry, and free from oxygen and moisture before charging with refrigerant. Its inert nature prevents oxidation and helps maintain system integrity, making it an essential part of safe and efficient installation and maintenance practices.
In manufacturing and laser cutting, OFN serves as an assist gas, creating an oxygen-free environment that produces cleaner, more precise cuts with reduced oxidation and improved edge quality – particularly when cutting stainless steel and other metals requiring a polished finish.
Gas Link Group supplies industrial-grade OFN in a range of cylinder sizes to suit workshops, field engineers, and production facilities. For larger users, micro-bulk and bulk supply options are also available, providing a reliable, cost-effective, and continuous source of gas for high-demand operations.
All OFN supplied by Gas Link Group is produced, filled, and tested to strict purity and safety standards, ensuring consistent performance and compliance across every industrial application.
