Antistatic Filtration Solutions

Engineered by inserting antistatic threads/yarns into the fabric structure to control static build-up, improve safety and ensure reliable performance in critical filtration applications.

EN 1149-1 EN 1149-3 ATEX Applications
Antistatic woven filtration fabric with conductive black yarns woven through the white base at regular intervals

How It Works

Antistatic (conductive) threads/yarns are inserted into the fabric at defined intervals and in selected direction(s) to dissipate or decay static charges effectively.

Direction

Antistatic threads can be inserted in weft, warp or both directions depending on application.

Common Spacings

5 mm / 10 mm / 25 mm. Other spacings available on request.

Performance Level

Spacing and orientation determine the level of antistatic performance required.

Antistatic Performance Options

SS Blend (Conductive)

EN 1149-1 · Requires Earthing / Grounding

Stainless steel blend yarns provide a true conductive path for static charge dissipation when the system is properly earthed.

  • Provides conductive performance with earthing
  • Meets EN 1149-1 standard
  • Ideal for processes with earthing facilities

Carbon Blend (Dissipative)

EN 1149-3 · No Earthing Required

Carbon blend yarns provide static charge decay capability without the need for earthing or grounding.

  • Dissipative performance without earthing
  • Meets EN 1149-3 standard
  • Ideal for applications where earthing is not possible

Verified in our own laboratory

Antistatic properties are tested in-house for surface resistivity, decay half time and shielding factor, to EN 1149-1 and EN 1149-3. See our test capabilities.

Application Examples

Antistatic centrifuge filter bag, conductive yarn stripes running around the side wall and cone
25 mm spacing · one direction

Centrifuge Bags (Pharma Industries)

Antistatic yarns at 25 mm spacing in either the warp or weft direction — a common specification for pharmaceutical centrifuge duty where solvent-wet powders are handled.

Antistatic fluid bed dryer bag assembly, conductive yarn grid visible across the bags, with a magnified inset of the weave
10 mm spacing · both directions

Fluid Bed Dryer Bags

A tighter 10 mm grid in both directions for fluid bed drying, where high air velocities over dry powder generate significantly more static charge.
