Sintered Mesh Filter Elements for
Self-Cleaning & Backwash Systems
The high-end element for the most demanding self-cleaning service — polymer melt back-flush, HT flue gas pulse-jet, FCC regenerator dedusting, candle filters and severe-corrosion chemical service. Retrofit-ready for Pall, Mott, Bekaert, Bopp, Gneuss, Maag and other OEM platforms.
Why Sintered Mesh Wins Here
Three Service Domains Where Only Sintered Mesh Survives
Wedge wire and woven mesh self-cleaning elements dominate liquid water service. But when conditions get extreme — high temperature gas, polymer melt or severe chemical service — sintered mesh is the only element that holds permanent micron rating across years of cyclic backwash.
High-Temperature Gas (> 200 °C)
FCC regenerator dedusting, biomass gasification gas filters, HT flue gas pulse-jet, blast furnace gas filtration. Wedge wire deforms, polymer media fail — sintered mesh stays stable up to 800 °C (310S).
Polymer Melt Back-Flush
PET, PP, PE, BOPP, BOPET — 220–310 °C, 100–400 bar continuous cycling. 7-layer sintered mesh is the field-proven media for Gneuss, Maag, Kreyenborg, BKG and Coperion automatic screen-changers.
Severe-Corrosion Chemical
Strong acid streams, halogen-bearing chemistry, sour gas. Hastelloy C-276 sintered mesh delivers permanent micron rating in service where 316L fails within months.
Element Design Characteristics
Why OEMs & End Users Choose SINFT Sintered Mesh Elements
The element determines what the self-cleaning system can do. Six engineering priorities matter to OEM integrators and end users — and SINFT optimizes for all of them.
Up to 800 °C
316L to 600 °C, 310S to 800 °C — only metal media survive sustained high-temp pulse-jet cycling.
5-Layer Reinforced
Protection & reinforcement layers carry the pulse load; precision layer holds the micron rating.
Permanent Micron Rating
Diffusion-bonded structure does not drift with backwash cycling — verified across 3–5+ years field service.
Zero Media Migration
No fiber shedding — critical for polymer melt, food, pharma and semiconductor service.
Material Versatility
304 / 316L / 904L / Duplex 2205 / Super Duplex 2507 / 310S / Hastelloy C-276 / Electropolished.
OEM Drawing-to-Order
Custom-built for any housing — Pall, Mott, Bekaert, Bopp, Gneuss, Maag, Kreyenborg, BKG.

Customer Concerns
Top 5 Questions from OEM & End Users
1. Why is sintered mesh the preferred media for high-temperature self-cleaning filters?
add
Above 200 °C, wedge wire deforms, woven mesh distorts, and pleated polymer or paper media fail outright. Diffusion-bonded sintered mesh retains permanent micron rating and mechanical strength up to 600 °C (316L) or 800 °C (310S). That’s why FCC regenerator dedusting, biomass gasification gas filters and HT flue gas systems specify sintered mesh as the only viable self-cleaning element.
2. What pressure differential can sintered mesh elements survive during pulse-jet cleaning?
add
5-layer sintered mesh elements survive backwash pulse differential of 5–30 bar without permanent deformation or rating drift. The reinforcement layers carry the load while the precision layer holds the micron cut. 7-layer construction is rated for severe cycling on polymer melt back-flush filters (300+ bar).
3. Can SINFT supply retrofit sintered mesh elements for existing self-cleaning filter OEM platforms?
add
Yes. SINFT custom-manufactures retrofit elements for all major sintered mesh OEM platforms — Pall PMM, Mott HyPulse, Bekaert Bekipor, Bopp HiCo, Filtrec, Eaton DCF, Hydac and others. Drawing-to-order with documentation, materials traceability and integrity test. Typical cost savings vs OEM original part: 30–60%.
4. Which material for polymer melt back-flush service?
add
Polymer melt back-flush at 220–310 °C, 100–400 bar demands 7-layer 316L sintered mesh — the only construction that survives sustained melt-pump pressure and continuous cycling. Standard on Gneuss, Maag, Erema, Kreyenborg, BKG and Coperion automatic screen-changers.
5. What’s the material guide for typical self-cleaning service?
add
304 for general industrial water (cost-effective). 316L for industrial recirculating water. Duplex 2205 / Super Duplex 2507 for seawater and high-chloride wastewater. Hastelloy C-276 for severe acidic chemical service. 310S for HT flue gas above 600 °C. Electropolished 316L for pharma cGMP and food-grade applications.
