Nitrogen Generator Paisley
On-Site Nitrogen Generation Paisley
Stop depending on nitrogen deliveries and take control of your gas supply.
A nitrogen generator connects to your compressed air system and produces nitrogen whenever you need it, at the purity you require.


How Nitrogen Generation Operates
Nitrogen makes up 78% of the atmosphere. Generation means separating it from other gases in the air.
Membrane separation
Membrane generators push compressed air through a membrane. Oxygen and water vapour pass through the walls, leaving nitrogen behind. These units produce nitrogen at 95% to 99.5% purity.
Pressure Swing Adsorption
These generators use carbon molecular sieves. Oxygen molecules stick to the sieve under pressure whilst nitrogen passes through.
The system uses two chambers – one produces nitrogen, while the other releases oxygen at a lower pressure. This method produces nitrogen up to 99.999% pure.

Nitrogen Applications
Nitrogen serves many industries across Paisley. Common uses include:
- Food processing and packaging: Nitrogen displaces oxygen and moisture that support bacterial growth. It extends shelf life by flushing packaging without the use of chemical preservatives.
- Chemicals and pharmaceuticals: Nitrogen doesn't react with most compounds, making it useful for powder handling and product packaging.
- Electronics and manufacturing: Soldering in nitrogen reduces oxidation and improves joint quality.
Business Benefits
Nitrogen generators offer practical advantages beyond gas supply.
Convenience
Bottled nitrogen means estimating usage, scheduling deliveries, and storing heavy cylinders. A generator produces nitrogen when you turn it on.
Environmental impact
Delivery lorries carry heavy gas bottles across Paisley and the surrounding areas. On-site generation eliminates these regular trips.
Cost savings
Air is free. With bottled nitrogen, you pay for delivery, cylinder maintenance, and handling. On-site generation can reduce nitrogen costs by up to half. Many businesses recover their equipment costs within twelve months.
