The filter cartridges are selected keeping in mind  various parameters, as the required efficiency, the pressure loss allowed and the type of impurities to be separated from the gas.

The cartridges can separate from the gas both liquid and solid impurities.
The cartridges for the separation of liquid particles are the coalescents one, because they agglomerate the particles in the form of mist bigger drops, making them fall to the bottom of the filter.

DB Progetti cooperates with leader companies on joint projects, such as the design and implementation of coalescing elements plates for gas filtration skid of Nuovo Pignone Bari.
Over the years this collaboration has increased, with more and more complex projects and applications.
