Gas Filtration

Even when the contaminants have been removed at the extraction point through effective particle filtration inside the sample gas probe, there is still a risk of finer dust entering the measuring system.
For this reason effective analysis filters are required, but also for use in stationary or portable sample gas conditioners. These can be in-line filters or panel filters with housings made from various material combinations. Equipped with easy to change filter elements with various retention rates and an adequate filter size they can be used for a wide range of applications.
