The AirSep N2WAVE™ Modular Series is a scalable range of Pressure Swing Adsorption (PSA) nitrogen gas generators designed to produce nitrogen on site from compressed air.
Using Carbon Molecular Sieve (CMS) technology, the N2WAVE Modular Series separates oxygen from compressed air, allowing nitrogen to pass through as the product gas. The modular design provides a flexible solution for businesses that need reliable nitrogen generation today, while retaining the ability to increase production capacity as their requirements grow.
With nitrogen flows from approximately 1.8 CFM to 117.8 CFM at 95% purity, and from 0.2 CFM to 12 CFM at 99.999% purity, the N2WAVE Modular Series can be configured for a wide range of industrial and commercial applications. Product outlet pressures can reach up to 124 PSIG, depending on system configuration.
The compact footprint and modular construction make these PSA nitrogen generators particularly suitable where installation space is limited or future expansion is important.
The N2WAVE Modular Series combines PSA nitrogen generation technology with a compact, expandable design.
One of the main advantages of the N2WAVE Modular Series is its ability to grow with your nitrogen requirements.
If your nitrogen demand increases, additional modular units can be added to increase overall production capacity. This avoids the need to replace an entire generator simply because your business has expanded.
The modular construction provides a small footprint compared with many conventional nitrogen generation systems.
This makes the N2WAVE Modular Series suitable for installations where available floor space is limited.
The N2WAVE Modular Series can produce nitrogen across a range of purity levels, from 95% through to 99.999%, depending on the selected configuration and required flow rate.
Produce nitrogen directly at the point of use from compressed air, reducing dependence on delivered nitrogen cylinders or bulk gas supplies.
The modular design is intended to simplify installation and provide flexibility when integrating the generator into an existing compressed-air and nitrogen distribution system.
Additional modules can be installed as nitrogen requirements increase, providing a practical way to expand production capacity.
On-site nitrogen generation can help reduce costs associated with delivered nitrogen, including cylinder rental, delivery charges and environmental surcharges.
The N2WAVE Modular Series is designed for straightforward operation and automated nitrogen production.
The AirSep N2WAVE Modular Series uses Pressure Swing Adsorption to separate nitrogen from compressed air.
The system uses columns containing Carbon Molecular Sieve (CMS). CMS selectively adsorbs oxygen molecules when compressed air passes through the adsorption column.
Clean, compressed air is supplied to the nitrogen generator and directed into an adsorption column containing Carbon Molecular Sieve.
Under pressure, the CMS preferentially adsorbs oxygen molecules from the compressed air.
Nitrogen is less strongly adsorbed and passes through the CMS column as the product gas.
The resulting nitrogen is collected and supplied to the application.
Before the CMS becomes saturated with oxygen, the compressed-air flow switches to the next adsorption column.
The first column is depressurised to atmospheric pressure, causing the adsorbed oxygen to be released.
A nitrogen purge assists the regeneration process.
The adsorption and regeneration process continues automatically.
By alternating between adsorption and regeneration, the N2WAVE Modular Series can provide a continuous supply of nitrogen.
Under normal operating conditions and with appropriate system maintenance, the CMS is designed to be regenerative.
Traditional nitrogen generator installations can require careful planning around future capacity requirements.
The N2WAVE Modular Series provides a different approach.
Instead of selecting one large generator based solely on predicted future demand, the modular system allows additional capacity to be added as nitrogen consumption increases.
For example, a business may initially require a relatively low nitrogen flow rate. As production increases and nitrogen demand grows, additional modules can be installed to provide additional capacity.
This makes the N2WAVE Modular Series particularly useful for growing businesses, production facilities and applications where future nitrogen demand is difficult to predict.
The AirSep N2WAVE Modular Series is available across a range of nitrogen flow rates and purity levels.

Actual nitrogen flow depends on the selected configuration, nitrogen purity and operating conditions.
As a general principle, higher nitrogen purity requires a greater amount of compressed air and therefore results in a lower available product flow for a given generator configuration.
For accurate system sizing, the required nitrogen purity, flow rate, pressure and operating pattern should be considered together.
Different applications require different nitrogen purity levels.
The N2WAVE Modular Series can be configured to produce nitrogen at purity levels ranging from approximately 95% to 99.999%, allowing the system to be selected according to the requirements of the application.
Typical purity requirements may include:
Suitable for applications where a lower nitrogen concentration is sufficient and high gas flow is important.
Suitable for a broad range of industrial processes where increased nitrogen concentration is required.
Suitable for applications requiring a higher level of oxygen removal and a more inert nitrogen atmosphere.
Used for applications where very high nitrogen purity is required.
Suitable for demanding applications requiring ultra-high-purity nitrogen.
The correct nitrogen purity should always be determined from the requirements of the specific process.
The N2WAVE Modular Series can be configured around the requirements of the application and installation.
Potential system considerations include:
A nitrogen receiver can provide buffer storage between the generator and point of use, helping accommodate variations in demand.
Where nitrogen purity is critical, oxygen analysis and monitoring can be incorporated into the system configuration.
Where a specific nitrogen pressure is required at the point of use, pressure regulation can be considered as part of the installation.
Dew point monitoring can be specified where monitoring the moisture content of the gas supply is important to the process.
The modular design allows additional generator units to be added when nitrogen requirements increase.
The exact options and configuration should be determined according to the application, nitrogen specification and installation requirements.
Selecting an industrial nitrogen generator based solely on maximum flow can result in an incorrectly sized system.
The correct N2WAVE configuration should take into account:

The most cost-effective solution depends on nitrogen consumption, purity requirements, operating hours, compressed-air costs and the existing gas-supply arrangement.
Choosing the correct nitrogen generator requires several key parameters to be established.
Determine the minimum nitrogen purity required by your process.
Higher-purity applications generally require greater generator capacity and compressed-air consumption for a given nitrogen flow.
Calculate your average and peak nitrogen consumption.
It is important to consider both continuous and intermittent demand when sizing the system.
Determine the required nitrogen pressure at the point of use.
The N2WAVE Modular Series can provide product outlet pressures up to 124 PSIG, subject to configuration and operating conditions.
The nitrogen generator requires a suitable supply of compressed air.
The compressor system should be assessed for:
Consider whether nitrogen consumption is likely to increase.
This is where the modular design of the N2WAVE can provide a significant advantage, allowing additional modules to be added as demand grows.
The compact footprint of the N2WAVE Modular Series makes it suitable for installations where space is limited.
The AirSep N2WAVE Modular Series is a range of PSA nitrogen gas generators designed to produce nitrogen from compressed air. Its modular construction allows production capacity to be increased by adding additional modules as nitrogen requirements grow.
The N2WAVE uses Pressure Swing Adsorption technology and Carbon Molecular Sieve to separate nitrogen from compressed air. The CMS adsorbs oxygen while allowing nitrogen to pass through as the product gas. The adsorber is then regenerated through depressurisation and nitrogen purging before the cycle repeats.
The N2WAVE Modular Series can produce nitrogen from approximately 95% to 99.999% purity, depending on the configuration and required flow rate.
The N2WAVE Modular Series provides flows from approximately 1.8 CFM to 117.8 CFM at 95% purity, and approximately 0.2 CFM to 12 CFM at 99.999% purity.
The N2WAVE Modular Series can provide product outlet pressures up to 124 PSIG, depending on the configuration and operating conditions.
Yes. Scalability is one of the main advantages of the Modular Series. Additional modular units can be added as nitrogen demand increases, allowing production capacity to grow with the application.
Yes. PSA nitrogen generators use compressed air as their feed gas. A suitable compressor and air-treatment system are required to provide the necessary air flow, pressure and quality.
For suitable applications, an appropriately sized N2WAVE generator can provide an alternative to delivered nitrogen cylinders. The suitability depends on nitrogen consumption, purity, pressure and operating requirements.
Yes. Nitrogen is commonly used as an assist gas in laser cutting, and an appropriately specified N2WAVE system can provide on-site nitrogen for this application.
Modular nitrogen generators can be used across industries including food and beverage, manufacturing, laser cutting, electronics, pharmaceutical, chemical processing, oil and gas, metal processing and plastics manufacturing.
Carbon Molecular Sieve, or CMS, is the adsorbent material used in the PSA process. It selectively adsorbs oxygen molecules from compressed air under pressure while allowing nitrogen to pass through as product gas.
Yes. The CMS is regenerated as part of the normal PSA cycle. When an adsorption column approaches saturation, the compressed-air flow switches to another column and the first column is depressurised. A nitrogen purge assists the removal of adsorbed oxygen.
The main advantage is scalability. Instead of installing a large system based on predicted future demand, businesses can start with the capacity they need and add additional modules as nitrogen consumption increases.
A nitrogen receiver can be incorporated into a nitrogen generation installation to provide buffer storage and help manage variations in demand. The required receiver size depends on the application and consumption profile.
How do I select the correct N2WAVE model?
The correct configuration depends on your required nitrogen purity, flow rate, operating pressure, compressed-air supply and application. Future demand should also be considered because the modular system can be expanded.
It can be, particularly for businesses with consistent or high nitrogen consumption. On-site generation can reduce costs associated with cylinder rental, deliveries and other gas-supply charges. The actual financial benefit depends on nitrogen consumption, electricity and compressed-air costs, operating hours and the existing supply arrangement.
