Discover our Gas Phase Filtration solutions
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.
Corrosion Control
Corrosion protection with electronics by effectively filtering contaminant gases from the outdoor air.
VOC Control
Removing VOCs from the ambient air to protect people with our reliable filtration solutions.
Odor Control
The presence of odor-intensive gasses must be controlled to prevent negative effects on the environment and health of workers.

Comprehensive portfolio for your processes
Every industry faces different challenges in regard to occupational and process safety with their specific raw materials or manufacturing processes. Some of these disruptive factors can be traced to the development or presence of undesirable gases. Therefore, individual requirements need to be identified in order to design the most effective Gas Phase Filtration solution. Our current focus is on corrosion control with electronics as well as odor and VOC control.
Industries that rely on our solutions
![Pulp and paper industry](/media/_processed_/2/6/csm_gasphasenfiltration-papier-und-zellstoffindustrie_20ba9a1ea9.png)
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](/media/_processed_/5/4/csm_gasphasenfiltration-petrochemische-industrie_e35a3225d5.jpg)
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](/media/_processed_/5/a/csm_gasphasenfiltration-korrosionsschutz-rechenzentren_f04a141aaa.jpg)
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](/media/_processed_/d/c/csm_gasphasenfiltration-VOC-abwasseraufbereitung_e8b39ace2c.jpg)
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.
![Airports](/media/_processed_/0/d/csm_gasphasenfiltration-VOC-kontrolle-flughaefen_2ec8d6132b.jpg)
Airports
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](/media/_processed_/6/9/csm_industrie-chemische-industrie-duengemittel-header_e4065ca1a1.jpg)
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.
