AVX-0801
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
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
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
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.
AVX-0805
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
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.

- Filter elements
- Reactor internals (screens & supports)
