A full range of fiberglass functional felts—crafted with meticulous care, backed by uncompromising quality.
Filter felt
Filter felt is manufactured from high‑quality alkali‑free or medium‑alkali glass fibers, formed via a wet‑process and finished with a surface coating. It offers exceptional filtration accuracy, excellent air permeability, superior corrosion resistance, and high dust‑holding capacity. The material features a uniform texture, fine and evenly distributed pores, and is free of fiber shedding or particle loss. It effectively filters particulates and impurities from gases and liquids, making it suitable for a wide range of applications, including industrial filtration and environmental treatment. With high filtration efficiency and a long service life, it can be custom‑designed to meet specific media and precision requirements.

1. Product Description
Filter felt is manufactured from high‑quality alkali‑free or medium‑alkali glass fibers, formed via a wet‑process and finished with a surface coating. It offers exceptional filtration accuracy, excellent air permeability, superior corrosion resistance, and high dust‑holding capacity. The material features a uniform texture, fine and evenly distributed pores, and is free of fiber shedding or particle loss. It effectively filters particulates and impurities from gases and liquids, making it suitable for a wide range of applications, including industrial filtration and environmental treatment. With high filtration efficiency and a long service life, it can be custom‑designed to meet specific media and precision requirements.
2. Core Explanation
• High filtration accuracy, with fine and uniform pores, effectively capturing dust and impurities ranging from 0.1 to 10 μm; filtration efficiency exceeds 99.9%, suitable for diverse filtration requirements.
• Excellent breathability, high dust-holding capacity, low filtration resistance, and no obstruction to fluid flow; it also rapidly adsorbs impurities, facilitating easy cleaning and regeneration.
• Excellent corrosion and temperature resistance, suitable for demanding filtration conditions such as acidic or alkaline environments and high temperatures; resistant to aging and damage, with a long service life.
• Uniform texture, no fiber shedding or flaking, and does not contaminate the filtration medium; filtration precision, dimensions, and shapes can be customized as needed, with excellent compatibility.
