Nitrogen & Oxygen: The Difference Between These Two Types of Generators

Nitrogen & Oxygen: The Difference Between These Two Types of Generators

Compresstech is a leader in the compressed air systems technology in the Philippines. We take pride in being a trusted provider of state-of-the-art solutions in various sectors and industries. We offer a range of nitrogen and oxygen generators to ensure our customers have access to a continuous supply of industrial gases at the lowest costs.

If you are interested to learn more about these options, this article will guide you through everything you need to know about these two types of generators. And to ensure that you’ll understand the importance of investing in one, we’ll first take a look into how these generation solutions can benefit you.

The Benefits of On-Site Nitrogen & Gas Generators

Industrial gases prove to be a diverse solution as they provide a wide range of uses for an extensive scale of industries – from food packaging to mining. It is for this reason why the demand for on-site generators, which is considered a part of the compressed air system, is steadily growing. This solution opens up opportunities for energy-efficiency and cost-saving for manufacturers and consumers alike.

On-Site Nitrogen Generator

As the name suggests, a nitrogen generator is used to produce nitrogen gas. It has the ability to provide a consistent supply of nitrogen for manufacturers who depend heavily on this gas for their business.

How it Works

It functions by separating N2 molecules from the atmospheric air (composed of 20.9% oxygen and 78% nitrogen) either through a membrane or Pressure Swing Adsorption (PSA) technology. When separated, these molecules are then stored and supplied using high-pressure nitrogen cylinders typically in the form of gas or liquid.


Nitrogen can serve a wide variety of applications among of which include, but not limited to:

  • Food Preservation –nitrogen is used for preserving the freshness of foods by delaying oxidative damages such as rancidity.
  • Pharmaceutical Uses – it is also present in all major drugs including antibiotics and used to preserve biological specimens.
  • Electronic Uses – it is used in heat suppression systems for computer and technology equipment such as computer CPUs.

On top of these, nitrogen also plays a role in the production of light bulbs, fertilizers, stainless steel, integrated circuits, and diodes.

On-Site Oxygen Generator

Similar to nitrogen, oxygen is also a necessity to a wide range of commercial and industrial applications. Having your own oxygen generator allows you to produce your own in the most efficient manner.

How it Works

Oxygen generators work in the same manner as nitrogen generators only they generate oxygen by separating it from the nitrogen in the ambient air. As the oxygen molecules are extracted, the nitrogen molecules are vented to the atmosphere. The cycle is then repeated in another vessel to provide a continuous flow of oxygen.


A lot of industries benefit from the many applications oxygen generators offer. Among these include:

  • Aquaculture
  • Hospitals
  • Jewelry manufacturing
  • Mining
  • Pharmaceutical
  • Welding

In the advent of on-site generators, the method of purchasing nitrogen and oxygen gases in bulk is already a thing of the past. These technological advancements have paved the way for businesses to save on energy and costs allowing for increased revenues.
