Molecules of oxygen, water vapor and carbon dioxide are small in size, which can quickly pass through the membrane wall and be discharged. Nitrogen molecules are larger and cannot penetrate the membrane, thus being enriched and delivered.

Product output: Nitrogen with a concentration of 95%–98%, extremely dry (dew point ≤-40℃), which can be directly used for tire inflation.

Comparison with PSA nitrogen generation technology: The nitrogen purity of membrane nitrogen generation is slightly lower (PSA can reach over 99.5%), yet it features a more compact structure, no moving parts, lower power consumption, lower operating noise and extremely simple maintenance.

II. Core Advantages of Nitrogen Tire Inflation (Exclusive to Membrane Nitrogen Generation)

Stable Tire Pressure and Anti-Tire-Burst Performance

Nitrogen is inert with low thermal expansion. Its tire pressure fluctuation is only ±0.1bar at high speeds and high temperatures, compared with ±0.5bar for ordinary air. Membrane-produced nitrogen is extremely dry and oxygen-free, which prevents rubber aging and wheel hub corrosion.

Long Pressure Retention and Less Inflation Maintenance

Nitrogen molecules are large and permeate slowly, achieving a tire pressure retention rate of about 92% versus around 78% for ordinary air. Free of water vapor, membrane nitrogen prevents long-term air leakage, and no supplementary inflation is needed for 3 to 6 months.

Fuel Saving, Lower Noise and Extended Tire Service Life

Stable tire pressure reduces rolling resistance, cutting fuel consumption by 0.1–0.3L per 100 kilometers. Nitrogen has poor sound transmission, lowering tire noise by 2–3 decibels. Its oxygen-free property inhibits oxidation and prolongs tire service life by 15%–20%.

III.Equipment Advantages (Exclusive to Membrane Nitrogen Generation)

✅ Compact and portable: Available in trolley-mounted and wall-mounted styles, plug-and-play with 220V power supply, ideal for small shops and mobile services.

✅ Instant nitrogen output: No preheating waiting, qualified nitrogen can be produced within 30 seconds after startup.

✅ No moving parts: Almost fault-free with extremely low maintenance costs, only regular filter element replacement is required.

✅ Low noise and low power consumption: Operating noise ≤60dB, power consumption is approximately 0.1kWh per vehicle.

VI.Membrane Nitrogen Generation vs PSA: How to Choose for Tire Applications

Membrane Nitrogen Generation: Nitrogen purity ranges from 95% to 98%. It features compact size, portability, instant startup, low noise, minimal maintenance and low cost. Ideal for small shops, mobile operations and scenarios serving fewer than 10 vehicles daily.

PSA Nitrogen Generation: Nitrogen purity ranges from 98% to 99.9%. It is bulky, equipped with moving parts, produces loud noise, requires relatively complicated maintenance and comes at a higher price. Suitable for vehicle fleets, logistics parks, scenarios serving more than 20 vehicles daily, as well as heavy-load and high-temperature working conditions.

Conclusion: Nitrogen with a purity of 95% to 98% fully meets the requirements for tire inflation, making membrane nitrogen generation the most cost-effective option.
