Polyester air slide fabric is a high-performance heavy-duty industrial fabric woven from high-quality polyester fibers (filaments or staple fibers). It plays a crucial role in the fluidization process of dry powdery materials, ensuring efficient and stable pneumatic conveying of these materials even under harsh continuous operating conditions, guaranteeing smooth, efficient, and low-friction transport.
- The max. length per roll: 50 M.
- Max Width: 2.6 M.
- Thickness: 4~10 MM.
- Heat-resistant: ≤150℃.
Description
Filmedia® air slide fabrics are manufactured from premium synthetic fibers using advanced integral weaving technology to provide reliable performance under demanding industrial conditions.
Woven tightly with consistent pore distribution, ensuring balanced airflow across the entire surface and eliminating dead zones.
Resistant to high impact, stretching, and deformation, guaranteeing high structural stability under heavy loads.
Low friction coefficient and low wear rate, significantly extending the service life.
Non-hygroscopic material that prevents caking, rotting, decomposition, and bacterial growth.
Facilitates complete unloading, leaving no material residue in the chute.
Demonstrates minimal shrinkage and maintains excellent performance even in high-temperature, high-humidity, and mildly corrosive environments.
Smooth surface, clear texture, no delamination, and no dust leakage (anti-dust return).
How Does It Work?
Air slide fabric is installed between the upper and lower channels of air slides to separate two cavities. High-pressure air fills the lower channel and penetrates evenly through the polyester air slide fabric into the upper channel. The dry powdery materials on top of the fabric are fluidized by uniform airflow, then flow smoothly relying on gravity to realize continuous pneumatic conveying.

Types of Airslide Fabric
We offer two different types of polyester air permeable fabrics to meet the needs of various industrial environments.
Filament Polyester Airslide Canvas
Provides excellent filtration, wear resistance, and high-temperature tolerance. It prevents moisture absorption, ensuring long-term operational stability.
Spun Polyester Airslide Canvas
Delivers superior tensile strength and structural integrity, ensuring the fabric remains dimensionally stable under high pressure and corrosive environments without stretching or deforming.
