1. Waterproof and antistatic polyester filter media has strong impact resistance and absorption capacity, the best in low temperature environment filter media.
2. The waterproof polyester filter media chemical stability is very high, and waterproof antistatic polyester filter media can resist all kinds of high corrosion and organic solvent erosion in a certain range of temperature and concentration.
3. Light weight, easy to install for polyester filter media

Waterproof and Antistatic Polyester Filter media suitable for mine, limestone, cement, iron and steel industries, alumina delivery, electrolytic aluminum, non-ferrous metal production, wood processing, food processing and pharmacy industry.
Tianyu developed in house needling technology since 1997.
We follow all process steps (preparation, carding, cross-lapping, in-line needling) with online quality checks.
We produce special polyester filter media for a wide range of markets and needs.
1.Micro polyester filter media
- Use of microfiber (up to 0,9 dtex) on the dust side;
- Alternatively use of multilobal sectioned shape fibers on the dust side;
Controlled low emissions
Increased bag lifetime
2. Meta-aramid/ Acrylic compound needle punched felt
Meta-aramid fibers blended with special acrylic fiber
- Needled on meta-aramid scrim
- Also available with different scrims such as PTFE
Good resistance to hydrolysis and oxidizing agents
Idea for acid environment
3. Anti static needle punched felt
- Use of epitropic fibers blended with standard ones in the batt to improve conductivity of the finished felt
- For better performances use of stainless steel fibres in the scrim
