Extraction and Filtering Unit with Active Coal

The extraction and filtering unit with activate coal filters is an air-cleaning technology through which an airflow containing pollutants passes through a filtering media containing active coal substance, before being expelled into the atmosphere. The coal filter media – thanks to its porosity – is capable of absorbing – filtering – the organic particles in the airflow.

By using the extraction and filtering unit with active coal, the airflow containing pollutants is carried through the filter(s) by mean of one or more industrial fans, which before them have installed  several cells or pocket multistage filters. These preserve the active coal efficacy by filtering and holding back dust pollutant particles.

The polluted airflow passing through the active coal layer loses its organic pollutant particles and it is directly expelled – cleaned – into the atmosphere. After a certain period, based on the amount of pollutants filtered, the exhaust active coal needs to be replaced.

The extraction and filtering unit with active coal filter is used in specific fields such as chemical and manufacturing industries with solvent emissions (industries using paints, printing industry, industrial dry-cleaner, degreasing processes, mechanical industry, fiber, rubber and artificial leather industries), as well as other chemical processes in which organic substances oxidation reactions in airflow occurs. Another application field of the filter media is food and its connected industries.

The extraction and filtering unit with active coal filter may be of two types: with cartridges (used for low pollutants concentration) or bed shaped (used for medium to high concentrations). The bed shaped filter type, treating higher airflow rates, is equipped with a fast loading/unloading mechanism to replace the activated carbon media.
