NitroFill E-135 Frequently Asked Questions

Is nitrogen really better than air in tires?

Yes, measurably -- nitrogen molecules are larger and drier than compressed air, so nitrogen-filled tires hold pressure longer, run cooler, and avoid the moisture that corrodes wheels and TPMS sensors from the inside. Air is already 78% nitrogen; the difference is getting to 95-99.9% purity, which is what a nitrogen generator for tires like the E-135 delivers.

What makes the E-135 the entry point of the line?

It's the all-in-one starter: a 3 CFM nitrogen generator with the automatic inflator built in -- self-calibrating, self-diagnostic, accurate to ±0.5 PSI. One compact unit converts and tops off tires with no extra equipment, at the lowest price in the NitroFill line.

What do I need to run the E-135?

A standard 110V outlet and shop air at 87-123 PSI delivering at least 5 CFM (filtered to 0.01 ppm). If your shop has a working compressor, you're most of the way there.

Which NitroFill nitrogen generator is right for my shop?

This E-135 fits lube shops, small tire stores, and dealers adding nitrogen tire inflation as a service. Doing sets of four regularly? The E-160 doubles output and converts four tires at once. High-volume tire store? The E-170 is the 13.5 CFM, 6-tire benchmark.

Can nitrogen service actually make my shop money?

That's the point of starting with the E-135 -- nitrogen tire fill is a chargeable service with per-tire conversion fees and top-off programs, and the machine's cost of goods is your existing shop air. Many shops recoup the unit within months of adding the service.

Is the NitroFill E-135 worth it?

The cheapest way into the largest nitrogen-service brand in the industry, with up to 99.9% purity and a 5-year warranty. See the Reviews tab above for buyer feedback.
