Withstands temperatures up to 150°C, suitable for garbage incineration and other high-heat applications.
Durable Polyester Fiber
Provides excellent abrasion resistance and dimensional stability, ensuring consistent filtration performance.
Customizable Options
Available in various sizes, shapes, and finishes to meet specific industrial filtration needs.
Features
Our filtration bags are crafted from 100% filament polyester fiber, ensuring high filtration performance. They are needle-felted, singed, heat-set, and rolled to produce durable polyester felt. The bags come in a range of weights (350gsm to 600gsm) and thicknesses (1.8-1.9mm), with excellent air permeability (10-15 m³/m²/min@12.7mmH2O). They feature high breaking strength and elongation, ensuring durability under stress. The bags are also available with functional finishes like anti-static, water and oil repellent, and PTFE membrane for enhanced performance.
Benefits
These filtration bags provide outstanding filtration efficiency, capturing tiny particles to maintain a clean production environment. Their high-temperature stability and chemical resistance make them ideal for use in harsh industrial conditions. The bags’ durability and abrasion resistance reduce the frequency of replacements, lowering maintenance costs. Additionally, their customizable options ensure a perfect fit for various filtration systems, enhancing overall operational efficiency.
Use Cases
Our filtration bags are widely used in industries such as cement, steel, power generation, chemical processing, food and beverage, mining, woodworking, textile, recycling, plastics, and automotive. In the cement industry, they capture particulate matter during production. In steel manufacturing, they control emissions and capture dust. Power plants use them for air pollution control, capturing fly ash and other particulates. Chemical processing facilities rely on them for filtering fine particles and dust. Food-grade applications ensure product quality by filtering airborne particles. Mining operations use them to control dust emissions, while woodworking shops capture wood dust. Textile manufacturing processes benefit from their ability to control lint and other particles. Recycling facilities use them to control dust and airborne particles, and plastic manufacturing operations ensure a clean working environment. Automotive paint booths and other manufacturing processes rely on them to control airborne particles.
