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.

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.
Gasphasenfiltration Petrochemische Industrie

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.

Reliable corrosion and odor protection with Viledon filterCair

For improved performance and efficiency of your gas phase filtration system

With customized service contracts or modules that can be individually combined with each other, we offer effective protection against gases in sensitive areas. In addition to unpleasant odors, aggressive harmful gases can also cause corrosion damage to electronic equipment. With the tailor-made Viledon filterCair Services, you can optimize your filtration system and thus protect your processes and employees.

Let us help you to realize an efficient and environmentally friendly system solution for your gas phase filtration to achieve a long-term reduction in your operating costs.

How can you profit from ISO 16890 in gas phase filtration?

Find the right filter solution for your site-specific requirements with ISO 16890

Standardized filter systems are frequently inefficient and do not make full use of their potential for optimization. The more specifically filter systems are customized to the respective ambient conditions and plant requirements, the greater performance and reliability they achieve. 

Our experts work with you to develop the best filter solution for your system based on the testing standard ISO 16890. As part of this filter evaluation, the typical urban and rural particle size distributions are evaluated based on the fine particulate matter fractions PM1, PM2,5 and PM10, and appropriate filtration efficiencies are determined.
