Compressed air composes of other gases

Untreated compressed air always contains contaminants because of the nature of the gas and how it is produced. The need for air treatment basically results from 3 characteristics of compressed air.

Contaminants

Oxygen: contaminant if oxidation is unwanted
Nitrogen: contaminant if oxidation is wanted

How are the contaminants formed?

Dry air is mainly composed of nitrogen (78%) and oxygen (21%). Air will keep the same nitrogen/oxygen ratio after compression, so additional treatment is needed to change this gas mix.

What problems can the contaminants cause?

Oxygen causes oxidation, leading to explosions or fire of flammables (fast oxidation) or to rotting processes and corrosion of metals (slow oxidation).
Nitrogen is an inert gas that can prevent oxidation to happen.

Pneumatech Gas Generators

Pneumatech designs and manufactures both standard and engineered on-site gas generator products. Nitrogen and oxygen generators are available with Pressure Swing Adsorption (PSA) technology, while also membrane technology is offered for lower nitrogen purity levels.

PPNG skid

PPOG Series - PSA Oxygen Gas Generators

Pneumatech offers a full line of Pressure Swing Adsorption Oxygen Generators for purities up to 95%.

PMNG Series - Membrane Nitrogen Generators

Membrane generators are an excellent choice in low (90%) to medium (99,5%) purity applications such as tire inflation, fire prevention, tank blanketing and pipeline drying.

PPNG Series - PSA Nitrogen Generators

Pneumatech offers a full line of Pressure Swing Adsorption Nitrogen Generators for purities up to 99.999%.

5 Benefits of an On-Site Nitrogen Generator

Nitrogen is a necessity for many businesses, but having someone deliver nitrogen to your site is often expensive and unsafe.

Are gas cylinders my only option for nitrogen?

Are Gas Cylinders my only option to get Nitrogen into my shop? - The simplest and satisfying answer is Yes! However realsitic answer is a big NO.

How can the purity of my Nitrogen Generator be affected?

How can the purity on the Nitrogen Generator changes when it is sized to deliver constant Nitrogen flow at required purity? Find the answer of the Pneumatech Experts here!

How can I verify the purity of gas from my nitrogen generator?

The purity levels in each of these applications varies and every product range has to be tested to determine its' purity levels and performance resulting in documented purity certificates.

Why is on-site gas generation a better alternative to nitrogen delivery?

Both gas nitrogen and liquid nitrogen are used in various applications for preservation, packaging, freezing and more. Most facilities are using on-site gas generation over outsourcing liquid nitrogen, but why? Find out here...
