Activated charcoal is a microporous form of charcoal, which can be produced from various raw materials, such as peat, wood, lignite and more. The charcoal atoms located on the inner surface of the activated charcoal exert an attraction on the surrounding gas and liquid molecules. Almost all industries and laboratories have the need to limit or control emissions into the atmosphere, especially if polluting toxic compounds are formed during processing. The treatment of emissions with activated charcoal is one of the simplest and least expensive procedures, provided that the type of contaminant has the right characteristics to be adsorbed by the charcoal. Otherwise, filters produced with synthetic resins cause a reduction in the absorption capacity of up to 50%.
Charcoals are not all the same, in fact there are types that are better suited to certain pollutants, and that provide higher yields. In some applications, the activity of activated charcoals can be enhanced by impregnating the internal sheets with substances having a catalytic effect and which result in chemical absorption.
The absorption capacity of activated charcoal filters varies according to the following parameters:
- Concentration of contaminants in gas or air
- Temperature and humidity
- Pressure
- Contact time between air or gas and activated charcoal
- Dimensions of the charcoal grain
The lifespan of the activated charcoal filter is subject to the same parameters, but is variable. In any case, we recommend replacing the filters every 9 months or at least once a year. To remind the user of this need, all Carbox® filters are supplied with Cunctator®. It consists of an electronic device that will remind the operator when to replace the filter by emitting an acoustic signal (6, 9 and 12 month versions available). The range of Carbox® filters is able to assure the best operating conditions in different applications. Activated charcoal filters are optimal for absorbing acid products (with cells made of PVC and stainless steel), and others more suitable for flammable substances (with PVC and polypropylene cells) are available. 4 or 6-cell filtering units are available depending on the customer’s needs. In addition, the CARBOX-VENT BE4 and CARBOX-VENT BE6, 4 or 6-cell filtering units already equipped with a single-phase motor are also available.
