NITROGEN GENERATORS

Nitrogen Generator for Formlabs Fuse X1

The Formlabs Fuse X1 is one of the most capable industrial SLS 3D printers ever brought to market at this price point. With a build volume of 330 × 330 × 565 mm and laser power up to 120 W, it demands a reliable, uninterrupted nitrogen supply – and Formlabs makes that clear in their official specifications.

This page covers the nitrogen requirements for the Fuse X1, the Flairmo generators we recommend, and how to set up a complete nitrogen supply for your installation.

What nitrogen supply does the Formlabs Fuse X1 require?

Formlabs specifies the following nitrogen requirements for the Fuse X1:

Parameter Specification
Minimum purity99.5% N₂
Continuous flow rate0.8 SCFM (22.65 l/min) minimum
Inlet pressure3.45 bar (50 psi)
Gas temperature at inlet18°C or above
Line fitting (printer-side)3/8" NPT

Like the Fuse 1+ 30W, the Fuse X1 requires an external nitrogen supply – meaning the nitrogen is generated or supplied outside the printer itself. What differs is the flow demand: the Fuse X1 requires significantly more nitrogen than the Fuse 1+ 30W, which determines which Flairmo generator is the right fit.

Our nitrogen generators come in two configurations depending on your compressed air situation: with an integrated compressor (internal air supply) or connected to an external compressed air source (external air supply). Both configurations deliver the same nitrogen output – the difference is in how the inlet air is supplied.

Our recommended nitrogen generators for the Formlabs Fuse X1

INTERNAL AIR SUPPLY

N2G-40CS - Integrated compressor

The N2G-40CS has integrated compressor, drying and filtration inside the generator cabinet, making it a standalone, plug-and-play nitrogen solution. No external compressed air required – just power and the printer.

RECOMMENDED IF:

  • You are installing in a lab, workshop, or production environment without central compressed air
  • You need a silent nitrogen generator with noise level below 55 dB(A) / 1m
  • You want a clean, self-contained unit with minimal installation footprint
  • You are looking for a flexible N2 generator solution with mounted wheels

EXTERNAL AIR SUPPLY

N2G-40 - External compressor

The N2G-40 connects to an existing external compressed air supply, delivering nitrogen at the purity, flow, and pressure the Fuse X1 requires. 

RECOMMENDED IF:

  • You have an existing central compressed air system that meets our ISO inlet standards (ISO 8573-1: Class 2.4.1)
  • You are setting up a dedicated printing environment and want to integrate nitrogen into your facility infrastructure
  • You want a simple, self-contained unit with minimal installation footprint
Note: If your facility does not have an existing compressed air supply meeting ISO 8573-1: Class 2.4.1, Flairmo can supply the complete system – oil-free compressor, refrigeration dryer, and 0.01 micron filter – fully compatible with the N2G-40.

FROM OUR CUSTOMERS

Nitrogen generators installed with Formlabs Fuse SLS printers

A selection of real customer installations from around the world.

Already running a Formlabs Fuse 1+ 30W?

We have supplied nitrogen generators to over 100 Fuse 1+ 30W installations worldwide. If you are expanding from a Fuse 1+ 30W setup to the Fuse X1, here is how our recommendations compare.

Printer Recommended generator
Fuse 1+ 30W (230V) N2G-15C
Fuse 1+ 30W (110V) N2G-10C
3× Fuse 1+ 30W (230V / 110V) N2G-40CS
Fuse X1 N2G-40 or N2G-40CS
The Fuse X1 has 7.5× the build volume of the Fuse 1+ 30W. The nitrogen demand reflects this: do not attempt to run the Fuse X1 on a generator sized for the Fuse 1+ 30W.

Why a dedicated nitrogen generator - not cylinders

For continuous SLS production, nitrogen cylinders create unnecessary operational risk: supply interruptions, logistics overhead, and ongoing cost that compounds over time. A Flairmo nitrogen generator produces nitrogen on demand from compressed air, with no deliveries, no cylinder management, and no supply gaps.

At 99.5% purity and a stable inlet pressure of 3.45 bar (50 psi), our generators are sized to meet the Fuse X1’s requirements continuously – not just at peak, but across full production cycles.

There is also a sustainability case. Cylinder-based gas supply means recurring transport, CO₂ emissions, and dependency on external supply chains. On-site generation eliminates all of that – nitrogen is produced where it is used, in the quantity required, with no logistics footprint.

About Flairmo nitrogen generators

FORMLABS FUSE 1+ 30W PRINT METHOD - SLS

The Formlabs 3D printer uses SLS (Selective Laser Sintering) a powder-bed process where a laser fuses thin layers of nylon powder to build parts.

In simple terms, SLS works like this: a thin layer of nylon powder (often PA11 or PA12) is spread across a heated build bed. A laser then “draws” the part’s cross-section, sintering (fusing) the powder where it hits. The bed drops slightly, a new powder layer is spread, and the laser fuses the next slice. Layer by layer, the part grows. The unused powder acts as natural support, so you can nest many parts in one job. When printing finishes, the parts cool, are unpacked from the powder, and then cleaned.

WHY IS NITROGEN ESSENTIAL FOR A FORMLABS FUSE 1+ 30W?

Nitrogen is essential for many 3D-printers for several reasons, including the Formlabs Fuse 1+ 30W. By replacing the oxygen-rich atmosphere in the 3D build chamber with nitrogen, you create a controlled environment with a extremely low oxygen level, which have great benefits for the 3D print. A high purity nitrogen environment helps:

  • Cleaner surface and smoother finish
  • Reduced yellowing over time on the printed part, when using white powders
  • By preventing oxidation, more of the unused SLS powder can be recycled and reused (from 30% to 50%)
  • Oxygen-free environment minimizes defects, resulting in higher-quality printed parts
  • Fewer interruptions and steadier runs over long print jobs
 
 
Practically, nitrogen is used to purge the chamber before a job and to maintain the setpoint throughout the build. Most SLS workflows target high-purity nitrogen 99.5% to achieve consistent results. The benefits above make a strong case for investing in on-site nitrogen for the Formlabs Fuse 1+ 30W.

All nitrogen generators from FLAIRMO can theoretically be used for Formlabs Fuse 1+ 30W, the right choice depends on your setup. Some customers run a single Formlabs printer that needs to be supplied with on-site nitrogen, then a smaller nitrogen generator can be used. If you operate multiple printers, larger nitrogen generators with higher flow rates is needed. Below is a simple guideline showing number of Formlabs Fuse 1+ 30W printers versus the recommended generator:

BOTTLED NITROGEN VS NITROGEN GENERATOR

One of the greatest advantages with nitrogen generators is how quickly you go can go break even with a one-time investment. If you have a 3D printer and rely on bottled nitrogen, you have five different expenses related to this:

  1. The nitrogen bottles
  2. Rental of the bottles
  3. Shipping of the bottles
  4. Handling of the bottles (ADR / Hazmat)
  5. Downtime when changing a nitrogen bottle
 

All these expenses add up rapidly over time, and if you use more than one bottle per week for your prints, your annual expenses is more than €12.000. In that case, you can reach break-even within 3-6 months by switching to a nitrogen generator. Try our ROI calculator to find out your payback time for investing in a nitrogen generator.

Safe & Efficient Grain Storage: The Benefits of a Nitrogen Generator for Grain Silos

When it comes to long-term grain storage, protecting your crops from pests is a top priority. Traditionally, fumigation with chemical gases like CO₂ or phosphine has been the go-to method. However, a safer, cleaner, and more sustainable solution is now available: on-site nitrogen generators. At FLAIRMO, we’ve developed the N2G-40CGS, a compact nitrogen generator specifically designed for gas-tight corn grain silos.

FLAIRMO N2G-40CGS
Nitrogen generator for grain silos - FLAIRMO N2G-40CGS - Nitrogen generator

Why Switch to a Nitrogen Generator in Grain Storage?

The FLAIRMO N2G-40CGS is not just another piece of equipment, it’s a game-changer for grain fumigation. This compact system allows farmers and grain storage operators to generate nitrogen gas on demand, replacing oxygen in sealed silos and creating a pest-free environment without chemicals.

Nitrogen, which makes up 78% of the air we breathe, is inert, non-toxic, and non-reactive. When pumped into a grain silo, nitrogen safely lowers the oxygen level to below 1%, a point at which most insects cannot survive. This method is known as controlled atmosphere fumigation, and it’s rapidly gaining traction in the grain storage industry.

Blog post 1

How the N2G-40CGS Nitrogen Generator Works

The FLAIRMO N2G-40CGS is a compact, all-in-one nitrogen generator for grain silos specifically made for this application. Using advanced Pressure Swing Adsorption (PSA) technology, the system extracts nitrogen from ambient air to create a clean, high-purity gas ideal for fumigation and preservation. The integrated air compressor draws in ambient air, which then passes through a built-in filtration system. Inside the PSA unit, oxygen, moisture, and other gases are removed, isolating nitrogen at purities suitable for pest control. This nitrogen is then delivered directly into the grain silo through a dedicated hose or pipeline. Once inside, the nitrogen displaces oxygen and creates a controlled low-oxygen environment, effectively neutralizing insects and other pests without the use of harmful chemicals. To ensure safe operation, the silo must be sealed gas-tight and equipped with a pressure relief valve to prevent over-pressurization during nitrogen infusion. This efficient setup enables safe, chemical-free grain protection on-site.

The Key Advantages of Onsite Nitrogen Fumigation

Using a nitrogen generator for grain silos offers a smart, sustainable alternative to traditional fumigation. By generating nitrogen on-site, you gain precise control over storage conditions, without relying on chemical treatments or gas deliveries. Nitrogen safely displaces oxygen in sealed silos, creating an environment where pests cannot survive, all while preserving the integrity of your grain and storage equipment.

This clean, inert gas offers long-term advantages for both operational efficiency and food safety:

  • Non-toxic and residue-free: Safe for humans, animals, and the environment.
  • Preserves grain quality: No impact on taste, color, or nutritional value.
  • No degassing required: Grains are ready for market after treatment.
  • No chemical resistance: Pests can’t adapt to oxygen deprivation.
  • No corrosion: Protects silos and equipment from damage.
  • Organic production compliance: Approved for use in certified organic systems.

With on-site nitrogen generation, you’re investing in a safer, cleaner, and more efficient grain storage solution, fully under your control.

What is an oxygen generator? Working principles, applications and how to size the right PSA system

An oxygen generator concentrates oxygen from compressed air to deliver a dependable, on-site supply with controlled purity, flow, and pressure. Most industrial and laboratory systems use the PSA technology with zeolite. On-site O₂ reduces manual handling, stabilizes operating cost, and simplifies compliance by enabling continuous monitoring and documented performance.

Oxygen generator
what is an oxygen generator

Definition and core principle

An PSA oxygen generator is a system that produces high-purity oxygen directly from compressed atmospheric air. While ambient air contains around 21% oxygen and 78% nitrogen, the generator separates and removes the nitrogen, delivering a clean, concentrated flow of oxygen. FLAIRMO oxygen generators are built to provide oxygen with purities ranging from 90% to 95%, on-site. This is made possible through PSA (Pressure Swing Adsorption) technology, which enables consistent, efficient on-site oxygen production.

Zeolite

How a PSA oxygen generator works

Pressure Swing Adsorption (PSA) is the core technology used to separate oxygen from nitrogen in ambient air. Inside the generator, this separation takes place within specialized towers filled with zeolite granular. This granular material acts as a high-tech filter that adsorbs nitrogen molecules while allowing high-purity oxygen to pass through for your application.

To provide a continuous supply of oxygen, the system utilizes a regeneration phase. PSA generators are built with two towers that work in tandem: while one tower is under pressure and actively adsorbing nitrogen, the second tower is “depressurizing.” During this shift, the trapped nitrogen is released from the zeolite and vented out of the system. This cleaning cycle ensures the zeolite is refreshed and ready to start the next adsorption phase. The number and size of these towers are customized based on your required flow rate and purity levels, ensuring the system is perfectly scaled to your needs. By constantly “swinging” between these towers, the generator delivers a steady, cost-effective, and reliable flow of on-site oxygen, with purities ranging from 90-95%.

ROI oxygen generator

One of the most common questions when considering an oxygen generator is: What kind of savings can I expect? The answer depends on your current oxygen supply method. If you’re relying on bottled and have a steady or high consumption, switching to on-site generation can result in significant cost reductions, many businesses see a return on investment within just a few months.

With bottled oxygen, you’re not only paying per unit, but also facing ongoing expenses such as rental fees, ADR (Dangerous Goods) handling, and frequent delivery costs. These recurring charges quickly add up. By comparison, an oxygen generator requires a one-time upfront investment, with low annual operating costs, mainly limited to power usage and basic maintenance.

In simple terms, most users experience a return on their investment (ROI) within 2 to 18 months. The more detailed answer depends on your specific setup, oxygen demand, and operational requirements, but for many, the long-term savings and independence are well worth the switch.

What is a nitrogen generator?

A Nitrogen generators is an on-site system that separates nitrogen from compressed air to provide a continuous, controlled supply of clean N₂ at your specified purity, flow, and pressure. In practice, a complete installation includes upstream air treatment (filters and dryers), then enters separation (PSA or membrane technology), a product buffer vessel, and controls with purity monitoring. Right-sized design delivers stable purity, predictable cost per Nm³, and direct availability at the point of use without cylinders or bulk logistics.

How a PSA nitrogen generator works – see applications

At FLAIRMO, we design our systems around the high-efficiency Pressure Swing Adsorption process. At the heart of every generator are dual carbon towers packed with Carbon Molecular Sieve (CMS). This specialized material acts as a high-tech filter; as compressed air flows through, the CMS “captures” oxygen molecules within its pores, allowing high-purity nitrogen to pass through to your application. The scale of your setup is directly dictated by your specific requirements. We tailor the number and dimensions of these carbon towers based on your required flow rate and nitrogen purity. While one tower is busy adsorbing oxygen under pressure, the other is regenerating by releasing the trapped gas, ensuring a seamless, 24/7 supply of nitrogen for your process

Typical applications include:

Switching to on-site nitrogen provides the consistency and purity that traditional deliveries often miss. For laboratories, a PSA nitrogen generator is vital for the precision of analytical tools like LC-MS, GC, and TOC systems, where stable flow is critical for accurate results. This reliable, inert supply also supports the electronics and manufacturing sectors, ensuring oxidation-free environments for laser cutting, soldering, and 3D printing.

In the food and beverage industry, nitrogen is essential for preserving taste, color, and mouthfeel by displacing oxygen. Furthermore, it serves as a key safeguard for infrastructure – preventing corrosion in dry sprinkler systems and protecting large heating plant accumulation tanks. By utilizing pressure swing adsorption, you secure a high-purity nitrogen source that protects both your equipment and your product quality every day.

How does a flairmo nitrogen generator work?

At FLAIRMO, we offer two primary ways to integrate nitrogen generation into your workflow. The best choice for your facility depends on your available space and whether you already have a compressed air infrastructure in place. Below, we break down our two core product lines – Internal Air Supply and External Air Supply – to help you determine which system fits your operation best.

Nitrogen Generators with Internal Air Supply

For facilities where space is at a premium, our internal air supply models offer a complete, plug-and-play N2 generator in a single cabinet. This compact solution has an oil-free compressor, drying, and precision filtration integrated into the cabinet, eliminating the need for a complex setup.

Despite being one of the smallest solutions available on the market, these systems are highly capable, delivering a flow range from 3 to 40 l/min. This makes them the perfect fit for laboratory environments and small production facilities that require high-purity nitrogen without the footprint of traditional industrial equipment. While the unit is entirely self-contained, we can easily pair it with an external vertical holding tank (such as our 90L model) if your process requires extra storage capacity.

Nitrogen generator for external air supply

Our external air supply line is a modular, high-capacity solution. A complete FLAIRMO solution includes an oil-free compressor, an air dryer, filter, PSA N2 generator and optional holding tank. By keeping these components separate, we can offer higher flow rates – ranging from 15 to 160 l/min – while keeping the footprint of the generator unit remarkably small and easy to place. If your facility already has on-site compressed air, you may not need the full suite of  FLAIRMO equipment. You can connect our nitrogen generator directly to your current air supply, but your existing air supply must meets the ISO standards (ISO 8573-1: Class 2.4.1)  for oil, moisture, and particle content. This allows you to leverage your existing investments while gaining the independence of on-site nitrogen.

The Importance of Air Treatment and Filtration

The longevity and precision of your nitrogen system depend entirely on the quality of the air fed into it. Contaminants like moisture, oil vapor, and fine particulates can “foul” the internal carbon molecular sieve (CMS) or membrane fibers, leading to a drop in gas purity and increased energy consumption. 

To prevent this, we utilize a high-end treatment chain featuring staged filtration and refrigerated drying to reach the precise dew point required. Every FLAIRMO system is engineered to meet ISO 8573-1 air quality standards. This rigorous upstream protection preserves the integrity of the adsorption beds and valves to ensure the hole system stays functional for many years.

ROI nitrogen generator

One of the most common questions when considering a nitrogen generator is: How much can I save? The answer depends on your current nitrogen supply setup. If you rely on bottled nitrogen and have high consumption, the cost savings can be substantial – many businesses reach break-even within just a few months. With bottled nitrogen, you’re not only paying per cylinder, but also recurring costs for rental fees, ADR (Dangerous Goods) handling, and frequent shipping costs. These expenses can add up quickly. In contrast, a nitrogen generator involves a one-time investment and minimal annual operating costs, primarily limited to power consumption. Over time, this results in significant long-term savings and improved operational efficiency. 

The short answer is, that you will notice revenue on your invested nitrogen generator within 2-18 months. The more nuanced answer is that it depends on your current setup and your nitrogen needs. Try our Return On Investment calculator on the link below.
