BMT
Broad Mesh Twilled Dutch Weave.
BMT-ZZ
Broad Mesh Twilled Dutch Weave, Zig-Zag.
The weft wires in BMT are not arranged to give a light-tight cloth, but have a pre-set spacing between each other.
Thus the weft mesh count and the retention varies somewhat over periodic intervals.
BMT ZZ, woven as BMT although with a special sequence, guarantees the highest possible accuracy and regularity of spacing.

Notes on Table:
The following indications are based on approximate values. The actual permeability performance depends on the working conditions. For single applications it might be necessary to carry out a technical feasibility test.
Column 5: The equation for filter performance is in the form DP = Y . V + M . V2 [V = airflow in cm/sec, DP = differential pressure in mbar . 10-3 determined with air at 20C, 1013 mbar.
Column 6: Tensile strength in Newton (N) of wire weave section 10 mm wide, 100 mm long.
Column 8: Weight kg/m2, stainless steel 1.4301
