ACTIVATED CARBONS
The activated carbon filter is the main ally for combating (bad) odors of natural and chemical origin in an aeraulic system. The activated carbon in the filter is in fact capable of adsorbing pollutants and odors
How activated carbon filters work
The structure of the activated carbon filter is geometrically identical to that of the other types of filters, but uses a different filter material. For this reason in the FCR catalog there are cartridge filters, pocket and polyhedron filters, flat cells, and loose activated carbon granules (useful in specific applications such as activated carbon beds).
The chemical-physical action of adsorption of organic substances is the main mechanism for eliminating bad odors.
Applications and limits of use of an activated carbon filter
Given the origin of the filter medium, an activated carbon filter fears relative humidity and high temperatures, more than one made of metal or glass microfibre: typically, in fact, the maximum operating temperature must not exceed 40-50 ° C and humidity rel. must remain below 70%.
Unlike many other types of filters, activated carbon filters can be regenerated at specialized companies.
Depending on the type of coal used, the following can be filtered, by way of example:
- organic odors
- acid gases
- radioactive isotopes (radioiodes)
- ammonia, amines and phosphines
- formaldehyde
for civil and industrial sectors such as airports, refineries, museums, laboratories, hospitals.
