Coral Activated Carbon What It Is What It's For

What are activated carbon

Activated carbons are porous materials obtained by carbonizing carbon-rich raw materials, such as wood, coconut shells or coal. The activation process, which may involve water vapor or other oxidizing agents, makes the charcoal structure highly porous and capable of adsorbing a wide range of chemicals.

What activated carbon is used for

Activated carbons are widely used in industrial air filtration systems to improve air quality by removing harmful gaseous pollutants and vapors. Their adsorptive capacity makes them effective tools in air purification, contributing to the protection of human health and the achievement of safer working environments.

Advantages and disadvantages of using activated carbon in air filtration systems

Advantages:

  1. Adsorption efficiency: Activated carbon has an exceptional ability to adsorb harmful chemicals in the air, ensuring effective purification.
  2. Versatility: They are suitable for the removal of a wide range of pollutants, including volatile organic compounds (VOCs), unpleasant odors, and toxic gases.
  3. Sustainability: The main source of activated charcoal is of natural origin, such as wood and coconut shells, making it a more sustainable choice than some chemical alternatives.

Disadvantages:

  1. Saturation: After a certain period of use, activated carbons reach saturation and lose their ability to adsorb additional substances, requiring replacement or regeneration.

For what pollutants are activated carbon filters useful?

Activated carbon filters are particularly effective in removing substances such as:

  1. Volatile Organic Compounds (VOCs): Includes substances such as solvents, hydrocarbons and other organic compounds that can be emitted from industrial processes.
  2. Unpleasant odors: Activated carbon can neutralize unwanted odors from industrial processes, waste or other activities.
  3. Toxic gases: Can adsorb harmful gases such as sulfur dioxide, ammonia and mercury vapor.

Coral's production range includes numerous filter units that make use of activated carbon for industrial air purification.

The Eurodry line of spray booths, which is particularly suitable for dry painting of parts of any size, allows the integration of activated carbon for the elimination of numerous toxic substances, while the Kubo high-performance filter unit for centralized systems is specifically designed and built for environments with high concentrations of VOCs.

In other cases, where the use of activated carbon is accessory, integrations are available for other types of systems: examples include the Karb filter unit, often used in symbiosis with paint booths and particularly suitable for removing solvent residues, and the Carbo module, perfect for deodorization, which can be used as a prefilter. Coral has also thought of simpler and cheaper but no less performing applications, such as the Olismoke table-top filter unit, perfect for tin soldering, equipped with an activated carbon filter cartridge.  

The activated carbon used by Coral for its systems is of high quality and high retention to ensure maximum efficiency and long life.
