Fibre & Special Felts

Dust removal frond gases is carried out thanks to the use of textile filter media.

The nature and granulometry of the particulate are among the main components to be evaluated when choosing the optimal filter medium.

Thanks to its long and consolidated experience in the industrial field, Testori offers a wide and distinctive range of special felts, with and without scrim, specifically developed to meet the needs of each customer and application.

The appropriate fibre selection, to be chosen from a wide range available, is strongly linked to the final application and process parameters (the main one is the operating temperature at full capacity).

The specificity of the application conditions may also require the application of special treatments to the filter media, which Testori offers in a wide choice.
