Frequently Asked Questions

Our nitrogen generator is suitable for various laser welding equipment, including fiber laser welding machines, YAG laser welding machines, semiconductor laser welding machines, etc., covering the full range from low power to high power.

Our standard model nitrogen purity can reach 99.99%, and the high-purity model can reach 99.999%, which can meet the needs of different precision welding processes.

Sure, we offer customized services that can be tailored to your nitrogen production, purity, pressure, usage environment, and other requirements.

Under normal use and regular maintenance, the service life of the nitrogen generator can reach 15 - 20 years, and the service life of the core component adsorption molecular sieve is about 8 - 10 years.

Adopting PSA pressure swing adsorption technology, utilizing the difference in adsorption performance between carbon molecular sieves for oxygen and nitrogen, oxygen is adsorbed under pressurized conditions, desorbed under depressurized conditions, and nitrogen is continuously produced in a cyclic manner.

Require intake pressure 0.7 - 0.8 MPa, intake temperature ≤ 40 ℃, oil content ≤ 0.01 ppm, dust content ≤ 0.01 μ m. It is recommended to use high-quality air compressors and refrigerated dryers in combination.

Our nitrogen generator adopts a silent design, with normal operating noise between 65 - 75 decibels, which meets industrial standards. If lower noise is required, a soundproof cover can be installed.

Energy consumption is related to nitrogen production and purity. Taking 99.99% purity as an example, the energy consumption per cubic meter of nitrogen is about 0.12 - 0.18 kWh, and the specific value depends on the model.

You can use the website contact form WhatsApp、 Contact our sales engineer by phone or email to inform you of your nitrogen requirements, and we will provide a detailed quotation within 24 hours.

The price of a nitrogen generator varies depending on factors such as output, purity, and configuration, ranging from tens of thousands to hundreds of thousands of yuan. For specific prices, please contact sales personnel for accurate quotes.

There is no minimum order quantity, but we also welcome bulk purchases with discounts for larger quantities.

We accept various payment methods such as T/T telegraphic transfer, L/C letter of credit, etc., usually 30% advance payment and 70% full payment before shipment.

Our nitrogen generator adopts a modular design, making installation relatively simple. You only need to prepare the gas source, power supply, and placement site, and we will provide detailed installation instructions and video guidance.

Yes, we provide on-site installation and debugging services, with professional engineers on-site to install, debug, and train operators to ensure the normal operation of the equipment.

Regular maintenance is required, mainly including replacing air filter cartridges, checking solenoid valves, calibrating instruments, etc. It is recommended to perform routine maintenance every 3 - 6 months.

Under normal use, the service life of carbon molecular sieve is about 8 - 10 years, which depends on the intake quality and frequency of use.
