2. Maximum width:2.3meters.
3. both filter cloth rolls and filter bags are available from YUANCHEN Filters.

Application for Cement Plant Filter Bags for dust collection system:

* Asphalt Durable construction required for abrasive, high temp environments. Hotmix or batch plants, whether natural gas, waste oil, fuel oil, etc.
* Cement Filters for all areas of plant: kilns bag houses, silo bin vents, nuisance dust collection, etc. Our filters exceed all EPA emissions standards (NESHAP, CMAT, MACT for portland cement, PM2.5, etc.).
* Chemical Filter fabrics for acidic or alkali compounds, corrosive or abrasive elements, etc. (lime, calc, fertilizer, plastics, etc.) Special treatments and fabrics available. We can advise on the best combination for performance and cost.
* Food Processing Food-grade fabrics construction available for dust collectors used in food production, transportation and packaging such as dust collectors on milling equipment, blenders, mixers, granulators, grain elevators, storage silos and more.
* Foundry and Metal Products Filters for units used on arc/induction furnaces, casting operations, and precious metal reclamation. Fabrics and coatings for use in high temperature environments with need for high efficiency fume and smoke.* Power Generation and Industrial Boilers Our filters exceed new EPA emissions regulations for boilers and power generation (Mercury and Air Toxics, Boiler MACT, NESHAPs, etc.). We have much experience working with biomass and coal power production facilities to overcome technical challenges to meet new EPA regulations. Filter fabrics and treatments include PPS, P84, PTFE/Teflon (fabric), fiberglass, and ePTFE membrane.
