NitroFill

Yes. Pitstop Pro is an authorized NitroFill dealer carrying the complete 7-machine NitroFill lineup. Authorized dealer status means factory-current units, real manufacturer warranty (we handle claims directly), authorized return processing, and access to NitroFill technical support.

NitroFill parts and warranty service through unauthorized resellers can void coverage. Always buy authorized.

Match the machine to your daily tire volume and use case:

NitroFill NF-123 ($2,250): Portable filler for mobile service trucks, fleet yards, roadside service. Runs off bottled or shop nitrogen, no built-in PSA generator. Best for off-site work.

NitroFill E-135 ($2,900): 3 CFM PSA generator with auto inflator. Entry-tier pick for small shops doing 15-25 fills per day.

NitroFill E-160 ($5,750): 6 CFM PSA with 4-tire conversion manifold. Mid-volume pick for dealership service lanes and mid-size shops doing 30-60 fills per day.

NitroFill E-170H ($6,850): 13.5 CFM PSA, manual controls. High-output for shops that prefer operator-driven cycles.

NitroFill E-170 ($8,100): 13.5 CFM PSA, programmable controls, 6-tire conversion manifold. The volume pick for dedicated tire shops doing 80+ fills per day.

NitroFill E-174 ($9,450): 13.5 CFM PSA, individual per-port PSI control. Best for shops servicing mixed vehicle types on the same job.

NitroFill E-175 ($13,500): 26 CFM PSA flagship. Built for commercial truck tires and fleet conversions.

For most independent tire shops, the E-160 is the smart starting point. For dedicated tire shops or dealership tire bays, jump to the E-170 or E-174.

PSA stands for pressure swing adsorption. Atmospheric air (78% N2, 21% O2, 1% other) flows into a vessel packed with carbon molecular sieve material. At elevated pressure, the sieve adsorbs oxygen and lets nitrogen pass through. The system swings between two vessels, with one producing nitrogen while the other regenerates by venting the captured oxygen to atmosphere.

End result: pure shop air goes in, 95-99% nitrogen comes out the other side, no consumables required beyond compressor air and electricity. The carbon sieve material lasts the life of the generator under normal use.

NitroFill PSA generators run 95-99% nitrogen purity depending on the model and flow rate. Industry standard for tire inflation is 95% N2 minimum. Premium tire programs target 99% purity.

Higher purity comes at lower flow rate (the same generator hardware can run higher purity at lower CFM, or lower purity at higher CFM). Most NitroFill models are tuned to deliver 95% at full rated CFM and can be slowed for higher purity if a fleet program requires it.

Depends on the model and the conversion technique:

E-135 (3 CFM): Roughly 15-20 minutes for a 4-tire conversion using the single-tire auto-fill cycle.

E-160 (6 CFM, 4-tire manifold): Roughly 8-12 minutes for a 4-tire car (all four tires simultaneously).

E-170 (13.5 CFM, 6-tire manifold): Roughly 5-8 minutes for a 4-tire car.

The 4-tire and 6-tire manifolds work by purging atmospheric air from the tire (usually 2-3 purge cycles) then filling to spec PSI with nitrogen. More purge cycles equals higher final N2 purity but longer conversion time.

Match the compressor to the generator CFM:

E-135 (3 CFM): Roughly 8-10 CFM input compressor (small 60-gallon vertical typically works).

E-160 (6 CFM): Roughly 15-18 CFM input compressor (5 HP, 80-gallon).

E-170, E-170H, E-174 (13.5 CFM): Roughly 30-35 CFM input compressor (7.5-10 HP, 80-120 gallon).

E-175 (26 CFM): Roughly 60-70 CFM input compressor (15+ HP rotary screw typically required).

PSA generators have an input-to-output ratio of roughly 2.5x to 3x. Undersized compressors will short-cycle and reduce N2 purity, so size up if you are between two compressors.

Most in-stock NitroFill machines ship within 2-5 business days from our Georgia warehouses with free U.S. shipping included. Freight transit time depends on distance, usually 3-7 business days to the contiguous US. Total order-to-doorstep is typically 1-2 weeks.

NitroFill machines ship via freight (LTL) since they are larger than parcel-shippable. Tracking and delivery confirmation included on every order.

Nitrogen tire inflation typically sells for $5-10 per tire at retail. The cost-of-goods on a PSA-generated fill is near zero (just compressor electricity). The equipment is the only meaningful cost.

A modest 20 tires per day at $7 per tire is $140/day, or roughly $36,400 per year. That pays back an E-160 ($5,750) in roughly 5-6 weeks of operating revenue, and an E-170 ($8,100) in roughly 8-10 weeks. Higher-volume tire shops doing 50+ tires per day see even faster payback.

NitroFill is typically a profit center, not a cost center, after the first few months.

Routine maintenance is minimal:

Every 500 hours: Drain compressor moisture filter, inspect intake filter. Annually: Replace coalescing filter element ($30-60), verify N2 purity at the output port using a nitrogen analyzer.

The carbon molecular sieve inside the PSA tank is rated for the life of the generator under normal clean-air-input operation. The main consumable is the inlet air filter, which catches compressor oil and moisture before it reaches the carbon sieve.

NitroFill carries a manufacturer parts warranty on the PSA generator, tank, and electronic controls. Specific coverage terms vary by model and are listed on each product page. Extended warranty options are available at order time.

All warranties are direct from the manufacturer. Pitstop Pro handles warranty claims as the authorized dealer, so you do not need to contact NitroFill support directly if something needs service.

Yes. Pitstop Pro offers 0% APR financing through Affirm and Klarna on most NitroFill purchases. Approval is decided in seconds at checkout. Terms typically run 12-24 months with no prepayment penalty.

For commercial buyers, leasing is available through Crest Capital, which can be useful if you would rather expense the equipment than capitalize it. See financing details or call (470) 208-2754 for a quote.

NitroFill is one of the most established names in nitrogen tire inflation because the brand combines equipment with the consumer-facing nitrogen tire program that runs through dealerships and tire shops. Other PSA generator brands (Parker, On Site Gas, Atlas Copco) build excellent equipment, often for industrial applications outside tire inflation. Generic Chinese-made PSA generators are also available at lower price points but typically without the dealer network or warranty support.

For tire shops, dealerships, and fleet programs that want a recognized US brand with established tire-shop pedigree, NitroFill is the safe pick. For pure-industrial nitrogen applications, the Parker/Atlas Copco class of equipment may be a better fit. Pitstop Pro carries NitroFill exclusively for the tire-inflation category.
