Nitrogen plays a vital role in industrial processes, from food packaging to electronics manufacturing. While many businesses rely on bottled or liquid nitrogen, this can come with high ongoing costs, logistical challenges, and safety risks. At SIA Compressors & Generators, we offer four advanced Nano nitrogen generator solutions that empower your business to generate nitrogen on-site safely, efficiently, and on demand.
Here’s a breakdown of our nitrogen generator range and how to choose the right system for your application.
How Do Nano Nitrogen Generators Work?
A nitrogen generator produces nitrogen gas on-site by separating it from the surrounding air. Since air is roughly 78% nitrogen and 21% oxygen, the generator’s job is to remove the oxygen (and other trace gases) to leave a high-purity nitrogen stream.
Two main technologies are used: Pressure Swing Adsorption (PSA) and membrane separation.
- PSA systems push clean, dry compressed air through columns filled with a Carbon Molecular Sieve (CMS) media. The CMS traps oxygen molecules while allowing nitrogen to pass through. The system alternates between columns: one producing nitrogen while the other regenerates this ensures a continuous supply. PSA systems can produce N2 gas up to a purity of 99.999%.
- Membrane systems use hollow fibres that allow oxygen, water vapour, and other gases to permeate out faster than nitrogen, leaving a concentrated nitrogen flow. Membrane systems can produce N2 gas up to a purity of 99.7%.
1. Nano GEN2 i4.0 Ultra-High Purity Nano Nitrogen Generators
Purity: 95% to 99.999%
Technology: Pressure Swing Adsorption (PSA)
Flow Rate: Up to 200.3 Nm³/h
Best For: Food packaging, laser cutting, electronics, pharmaceuticals, plastics.
The GEN2 i4.0 is our flagship Nano nitrogen generator, built for high-performance environments where purity and uptime are non-negotiable. Using advanced PSA technology, this system delivers ultra-high purity nitrogen from clean, dry compressed air. It features an intelligent multi-bank design, allowing for scalable capacity and built-in redundancy.
Key Benefits of the GEN2 i4.0:
- Remote monitoring & control via integrated PLC/HMI and Modbus
- Energy-saving PDES mode for optimised air usage
- Quick ROI: typical payback within 6–24 months
- 2-year warranty and full factory testing
- Modular growth: easily expand as demand increases
If your operations depend on continuous, ultra-pure nitrogen supply, the GEN2 i4.0 delivers unmatched performance and long-term value.

2. Nano NMG Nitrogen Generators (Cabinet)
Purity: 95% to 99.7%
Technology: Membrane Separation
Flow Rate: Up to 228 Nm3/h
Best For: Food packaging, chemicals, plastics, pharmaceuticals, blanketing applications
Nano NMG nitrogen generators (cabinet version) use membrane technology to separate nitrogen from compressed air, with no moving parts. An optional oxygen analyser provides a warning alarm should the purity fall below a set level.
Key Benefits of Nano NMG Nitrogen Generators:
- Low maintenance: no moving parts
- Instant gas: no mixing, compressed air in, N2 gas out
- Fast installation: plug-and-play configuration
- Energy efficient: low air consumption, reduced operational costs
- Safe: eliminates need for bottled gas storage or transport
- 2-year warranty and full factory testing
With five cabinet sizes and twelve membrane flow combinations available, the NMG range provides flexibility for industries needing moderate-to-high purity nitrogen without the complexity of PSA systems.
3. Nano GEN2 Mini Nitrogen Gas Generators
Purity: 95% to 99.999% (all except GEN2 060 - 99.95% or 500ppm)
Technology: Pressure Swing Adsorption (PSA)
Flow Rate: 0.3 to 18.8 Nm³/h
Best For: Laboratories, low-volume manufacturing, small-scale packaging, universities, breweries
The Nano GEN2 Mini “bottle killer” offers all the core features of the i4.0 range in a more compact, lower-flow package. Despite the smaller footprint, these generators still deliver high-purity nitrogen with minimal installation and maintenance demands.
Key Benefits of the Nano GEN2 Mini Nitrogen Gas Generator:
- Ultra-compact design: fits small spaces and lab environments
- Eco-mode: reduces energy use during low-demand periods
- 2-year warranty and full factory testing
- Safe and quiet operation with no cylinder handling
This range is ideal for smaller-scale operations that still require consistent nitrogen quality but without the space or budget for a large system.

4. High Purity Membrane Nano Nitrogen Generators
Purity: 95% to 99.7%
Technology: Hollow fibre membrane
Flow Rate: From 0.3 to 228 Nm3/h
Best For: Continuous low-to-mid flow nitrogen users in packaging, pharmaceuticals, and electronics.
This variation of the NMG range focuses on high purity applications, combining durable components with a simple design that requires no electricity. The compact, wall-mountable design makes them ideal for facilities with limited space. The integrated filtration system ensures gas quality and protects the membrane, making it a long-term solution for many industries.
Key Benefits of the High Membrane Nano Nitrogen Generator:
- No moving parts: quiet, dependable operation
- Instant gas: no mixing, compressed air in, N2 gas out
- Built-in filtration: 4-stage system protects quality
- Flexible installation: vertical or horizontal mounting
- Sustainability: lowers carbon footprint and OPEX
With built-in components and fixed purity control, these generators are ideal for facilities wanting a streamlined, cost-effective nitrogen supply with minimal oversight.
