AVX-0801

Why does my filter mesh blind within hours?

Differential pressure climbs far faster than the design curve. Cleaning intervals shrink from weeks to hours, and after each cleaning the recovery gets worse. Throughput drops while the pumps work harder.

  • Woven mesh
  • Sintered mesh
  • Filter elements

AVX-0802

Why do wire fragments appear downstream of my filter?

Fine wires or mesh fragments show up in downstream strainers, product samples or, worst case, in pumps and nozzles. Filtration still seems to work, until the damaged zone lets whole particle loads pass.

  • Sintered mesh
  • Welded & extruded mesh
  • Filter elements

AVX-0803

Why is liquid carrying over past my demister pad?

Droplets reach equipment the demister is supposed to protect: fouled compressor blades, off-spec overhead product, corrosion in downstream lines. The pad looks intact at the last inspection, yet the carry-over continues.

  • Knitted mesh
  • Reactor internals (screens & supports)

AVX-0804

Why does my belt press cake stay too wet?

Dry solids content drifts down over weeks while polymer consumption climbs. Operators compensate with slower belt speed, which cuts throughput; disposal costs rise with every extra percent of water hauled off site.

  • Spiral & filter belts

AVX-0805

Why do my screens crack at the welds or deform under load?

Cracks start at weld points or clamped edges of screen decks, baskets and support screens. Apertures stretch out of tolerance in the loaded zone, product quality drifts, and the same repair returns every few months.

  • Welded & extruded mesh
  • Perforated media
  • Woven mesh

AVX-0806

Why is my 316L mesh pitting in brine or chloride service?

Pinhole perforations and rust-brown spots on stainless mesh or elements, often within months in warm chloride streams. Failures cluster at crevices, clamped edges and welds; the bulk material still looks bright.

  • Woven mesh
  • Filter elements
  • Reactor internals (screens & supports)
