Atmospheric Plasma

Plasma is state of matter just as a solid, liquid or gas. Add enough energy to a gas and it partially ionizes into the fourth state of matter - plasma. Although found in virtually every home and business, gas plasma is not well known. In fact, plasma is quite common - it is estimated that 99% of the visible universe consists of plasma. Earthbound plasmas can be found in lightning strikes, fluorescent lighting, arc welders, and computer displays.


Atmospheric plasma is generated under atmospheric pressure conditions. PVA TePla’s atmospheric plasma is used to clean and modify the surface properties of a material in the absence of any electrical charge. PVA TePla’s design allows compressed air to be the standard treatment gas for most applications and provides for a very low cost of ownership.  Other gasses can be utilized depending on the specific application
