Molecular filters for reliable protection in sensitive areas

The intention of Gas Phase Filtration (also called molecular or chemical filtration) is removing gaseous contaminants from the air that could harmfully affect the occupants, contents or environment of a given space.

Industries that rely on our solutions

Pulp and paper industry

To make paper from wood and pulp, the raw materials must be treated chemically in a number of complex process stages. This results in gases that can cause corrosion in the surrounding machines and equipment.

Petrochemical industry

Petroleum is an important raw material that is used to produce numerous intermediate and end products by means of complex processes. Undesirable components such as sulphur, nitrogen and oxygen must also be removed.

Data centers

Dangers that can result in data loss lurk everywhere. Data centers, which are operated at higher air temperatures than before, are especially at risk. Even a temperature increase of 10 °C doubles the corrosion rate.

Wastewater treatment

Wastewater treatment often produces contaminant gases that cause unpleasant odors and can even damage sensitive electronics. Reliably protect your employees and processes from the consequences with customized filtration concepts.


The odor of kerosine and fuel is often present at airports. This smell is unpleasant and can even trigger physical reactions. The situation can be improved with reliable gas phase filtration of the air supply to your building.

Fertilizer production

Chemicals such as sulphuric acid and ammonia are used in the production of fertilizers. The processing of these chemicals produces contaminant gases that cause corrosion and must therefore be reliably removed from the process air.

Individual protection for your processes

Prevent corrosion damage and unpleasant odors with multi-stage filtration systems

Corrosion damage to electronic components increases plant costs over the long term. Unpleasant odors reduce the comfort level of workers. Protect your processes and employees from aggressive contaminant gases with a customized gas phase filtration system and a broad selection of Viledon ChemControl pellets.

The right filtration concept must be selected based on the maximum permissible contaminant gas concentration or odor intensity. The filter modules and multi-stage solutions are therefore tailored precisely to your needs and operate with the highest efficiency. We would be happy to advise you on selecting a solution and work with you to determine the right filtration solution for your process.
