The use and maintenance of the Nitrogen tire filling system does not include environmental dangers. Most parts are made of
metal and can be disposed in the regular way. The packaging of the Nitrogen tire filling system is 100% recyclable.
• Make sure that instructions concerning health, safety and environment are compliant with the local legislation and
regulations.
The Nitrogen tire filling system separates compressed air into nitrogen and an oxygen enriched air stream. The separation
system is based on membranes. The compressed air comes from a central system or from a dedicated compressor.
Fully Packaged models, designated by the "FP" letters after the model number, utilize a nitrogen storage vessel to store the
compressed nitrogen. Non-Fully Packaged models can be connected directly to the application or to a separate nitrogen
storage vessel. External storage devices must meet all applicable regulations and standards (local, state, country, federal, etc.)
pertaining to pressure vessels.

Ambient air contains nitrogen (78.1%), oxygen (20.9%), argon (1%), carbon dioxide, water vapor and traces of other inert
gasses. Pressurized air (A) is led through hollow fiber membranes (B). The various air components diffuse through the porous
wall of the membranes.
The diffusion rate differs for the various gasses:
• Oxygen and water vapor have a high diffusion rate and diffuse rapidly through the membrane wall.
• Nitrogen has a low diffusion rate and diffuses slowly through the membrane wall.
At the end of the membranes (C), pressurized nitrogen enriched air is released. This air can be lead to the application or to a
nitrogen storage vessel.
