UFusion: 3-layer gradient medium
Three-layer filter medium with a progressive fibre structure: coarse particles are captured in the open layers, fine ones in the dense layers. That increases capacity and extends service life — often with lower paper consumption than a single-layer medium for the same job.
Material and application
Material: Polyester, graded fibre structure (BICO fibre core)
Weights: 40–100 g/m²
Typical processes: grinding, honing, lapping, precision machining
Standard widths 0.39–1.0 m; widths above 1 m are made to order. Rolls are supplied in lengths from 50 to 300 m, and the core diameter is matched to the holder on your system.
Test standards
Weight is measured to DIN EN 29073.1, thickness to DIN EN 29073.2, tensile strength and elongation to DIN EN 29073.3 and air permeability to EN ISO 9237. Pore size is stated as Bubblepoint (BP) and Meanflow (MF).
All values are averages subject to normal production tolerances. The current datasheet (PDF) is always the reference.
