THE LEADING MATERIAL
Needle felt filter bags
The needle felt filter bags are mostly made of synthetic fibers. The requirements that can be placed on the hose depend primarily on the type of filter fiber. Specially developed materials can withstand high operating temperatures and are also resistant to very aggressive chemicals. The properties and durability of a filter bag are largely determined by the composition, structure, surface treatment and thickness of the material (weight).
From many years of practical experience in filter technology, FAVORIT draws on its know-how to select the right material combination for your needs from the wide range of fibers available.
