Polyester needle felts are the most commonly used material for the manufacture of filter bags. Low price, high quality and thermal resistance allow the use of this material in many filtration processes.
Polyester is used for dedusting processes where the temperature reaches up to 150°C (Peaks even up to 160°C).
Due to a wide range of applications this filter media can be delivered with a variety of additional properties that will meet the process requirements.
