Applications of Filter Bags in Baghouse Dust Collectors
Asphalt
Highly durable; suitable for environments involving high abrasion and high temperatures. Compatible with both hot-mix and batch asphalt plants, regardless of the fuel source (natural gas, waste oil, fuel oil, etc.).
Cement Plants
Suitable for filtration across various plant areas, including kiln baghouses, silo vents, and general dust collection systems.
Chemical Filtration
Filter fabrics designed for acidic or alkaline compounds, as well as corrosive or abrasive substances (such as lime, calcium-based materials, fertilizers, and plastics); specialized treatments and fabric types are available.
Food Processing
FDA-approved, food-grade fabric structures suitable for dust collectors used in food production, transport, and packaging—including applications on grinding equipment, mixers, blenders, granulators, grain elevators, and storage silos.
Foundry and Metalworking
Filters for electric arc furnaces, induction furnaces, casting operations, and precious metal recovery units. Fabrics and coatings designed for high-temperature environments requiring efficient capture of fumes and dust.
Power Generation and Industrial Boilers
Our filters meet the latest emission standards for the boiler and power generation industries (covering mercury, hazardous air pollutants, maximum allowable concentrations, national emission standards, etc.). We possess extensive experience with biomass and coal-fired power facilities and are capable of overcoming complex technical challenges.
