Reliable Protection From Gases in Sensitive Areas

Comprehensive gas phase filtration solutions

Individual protection for your processes

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

Contaminant gases can cause corrosion to high dollar equipment, as well as unpleasant odors to facility occupants. The consequences? Health impairments, expensive repairs, and unplanned downtimes. Our solutions of gas phase filtration products and services protect people and processes by reliably remove contaminant gases from the air.

We help you select the right filtration systems and products based on the maximum permissible contaminant gas concentration or odor intensity. The filter modules and multi-stage solutions are tailored precisely to your needs and operate with the highest efficiency.

Pulp and paper industry

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

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

Data centers

The loss of data can affect millions. Data centers, where systems typically operate at higher temperatures, special filtration is required. Even a temperature increase of 10°C doubles the corrosion rate.
Wastewater treatment

Wastewater treatment

Wastewater treatment often produce 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.


Considering the aerodynamics and accompanying fuel it requires to transport passengers by air, keeping fumes and odors at bay is an unnoticed convenience that's necessary. This is when reliable gas phase filtration of the air supply is an imperative component in the process.
Fertilizer production

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.
