Next check the status indicators/ gauges on the front control panel to ensure the unit is functioning properly. Check for any leaks as well as the inlet air quality. Once this has been done shut the unit down according to the manufacturer’s shutdown procedure.

Many nitrogen generator manufacturers use a combination of both coalescing and carbon filtration. Simply follow the instruction in the manual to change the filter elements.

Next, if you have a PSA (Pressure Swing Adsorption) nitrogen generator system, you will need to replace the muffler. Discard of the filter elements and muffler according to your company’s waste disposal process.

Valve replacement and oxygen sensor replacement will take place every three years typically, depending on hours of operation for the nitrogen generator. It is usually recommended that a factory trained service technician performs this procedure.

Once the maintenance items have been changed, restart the equipment based on the manufacturer recommended start-up procedure.

Nitrogen generator maintenance is required every six months and by simply following these easy maintenance steps your nitrogen generator should provide you with a continuous supply of clean nitrogen gas for many years to come.
