Polyester Needle-Punched Dust Filter Bags (Model 729)

2.1.1 Polyester Needle-Punched Dust Filter Bags (Model 729)
The polyester needle-punched filter bag (Model 729) is an industrial filtration material made from polyester fiber through a needle-punching process.
①Temperature Range:Continuous use: ≤130℃; short-term exposure: 150℃.
②Performance Advantages:Abrasion resistance and service life significantly outperform glass fiber fabrics under non-corrosive, medium-temperature conditions.High tensile strength, weak acid/alkali resistance, and filtration efficiency ≥99.5%.
③Applications:Dust control in cement, metallurgy, and food industries (e.g., mineral powder, woodworking dust collection).
④Limitations:Avoid high-temperature (>150℃), high-humidity, or strongly oxidative environments.
