MAHLE Service SolutionsThe MAHLE NitroPRO NTF-515B is the most versatile nitrogen tire-filling machine available in the market today! MAHLE's new NitroPRO NTF-515B is the professional's choice for nitrogen tire inflation with more nitrogen tire fill capability and variable nitrogen purity level flexibility. The NTF-515B offers your shop additional selling features of better fuel economy, longer tire life, and increased safety to motorists.

Nitrogen tire filling: Improves fuel mileage and increases tire performance for your customers.
Increases your bottom lineEasy, Convenient & Profitable

NitroPRO nitrogen production and delivery systems generate on-demand nitrogen using shop air and feature an on board storage reservoir, triple filtration system for system purity and membrane longevity and automatic shutoff for less air compressor on-time.

Fast Service Speed
All NitroPRO nitrogen generation stations feature a unique single tire inflation/deflation process to quickly exhaust air and moisture from the tire and fill with nitrogen. Multi-tire NitroPRO generators utilize an exclusive algorithm for the tire deflation/inflation process.

Easy N2 Service Validation
Every NitroPRO unit comes standard with a NitroPRO hand-held nitrogen purity tester to provide a quick and accurate nitrogen purity assessment for tires or reservoir. It is very convenient to use, very accurate and is highly reliable.

NitroPRO Membrane Technology
RTl's NitroPRO membrane performs consistently over a wide temperature range and will not deteriorate in cool garage environments. All NitroPRO polymer membranes are fully aged and stabilized before factory shipment to maximize and maintain NitroPRO's high nitrogen purity and generation performance for many years to come. NitroPRO is a large-bore membrane. That means the membrane fiber is less susceptible to contamination.

How Nitrogen Works:

Nitrogen is a Larger Molecule than Oxygen

  • Nitrogen cannot escape as easily through porous (rubber) material resulting in tires that maintain good tire pressure longer

Nitrogen is Safe and Stable

  • Nitrogen filled tires are safer and last longer
  • Nitrogen-inflated tires improve vehicle handling through proper inflation and consistently maintained pressure
  • Nitrogen is an inert, non-combustible and non-flammable gas; adversely, Oxygen is flammable and would fuel an automobile fire if one were to occur

Nitrogen is Cost Effective

  • Nitrogen maintains more constant pressure with temperature fluctuations which decreases rolling resistance and increases fuel economy
  • Nitrogen is a dry gas with no corrosive properties as found in compressed air
  • Nitrogen reduces premature aging of tires due to moisture
