The control of atmospheric emissions involves both the comfort and the ecological aspect of working environments. Respect for the environment, the EEC directives, and the well-being of the people who work in laboratories are all factors that require the use of systems which hold back acids or solvents present in chemical processing discharges, with a resulting air purification. The FilterBox PVC activated carbon filters are the answer provided by Plastifer to the problem of air filtering. What is Activated Carbon Activated carbon is a microporous granular carbon that can be produced with different raw material such as peat, wood or fossil coal. The activation process, carried out with vapour or chemical agents, produces millions of pores of molecular dimension that make up a great surface area with a ratio probably larger than 2,000 m2 per gram of activated carbon. Due to the Van Der Waals force, the carbon atoms present on the internal surface of the activated carbon attract the neighbouring gas molecules. Theintensity of such phenomenon is related to the molecular structure of the suctioned substances; some molecules are strongly attracted whereas others are not. Due to this mechanism, activated carbon can be used to eliminate one or more components of a mixture.
