Nitrogen Gas Inlet: Flow Capacity 5-200 L/min

Q: What maintenance is required for nitrogen gas inlets?

Regular inspection of seals and filters every 6 months, pressure calibration annually, and complete overhaul every 2-3 years depending on usage intensity

Q: Can nitrogen inlets handle other inert gases?

Yes, most are compatible with argon and other inert gases, but material compatibility and pressure ratings must be verified for specific applications

Q: How to prevent moisture ingress in nitrogen inlets?

Install desiccant filters upstream, maintain positive pressure, and use heated inlets in high-humidity environments

Component Specifications

Definition
