BOHNCKE filter bags: When no particles are allowed to pass through
BOHNCKE filter bags ensure clear media and clean end products, even with aggressive chemicals. Whether acid, alkali, or oil-containing liquids: Our filter bags are tight, durable, and customizable. For electroplating, chemical plant engineers, and anyone who cannot afford mistakes.
Filtration without compromises
BOHNCKE filter bags remove what doesn’t belong from process fluids. Residues, particles, and impurities stay in our bag. Because where clean results count, no contamination can slip through. Our filter solutions combine finely tuned materials with tightly welded processing, creating the foundation for smooth processes, consistent product quality, and minimal downtime.
Standard filter bags
Robust all-rounders for classic applications – economical and versatile.

Advantages: Cleanly resolved, noticeable in everyday life
Our filter bags do more than just particle retention. They improve the entire process, reduce downtime, and ensure consistent quality, even with chemically aggressive media.
- No bypasses: Laser-cut and welded design prevents leaks and fiber release.
- Compatible with all systems: Selectable ring types and sizes – suitable for your existing filtration technology.
- Less maintenance: Longer service life due to high dirt absorption capacity.
- Better results: Finely defined retention rates ensure consistent quality – without rework.
- Process reliable with aggressive media: Resistant to pH 0–14 – for pickling, electroplating, degreasing & more.
