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