Bulk powder handling is a critical aspect of various industries, ranging from cement production to food processing. In this context, both air slide fabric and fluidizing cloth play crucial roles in facilitating the movement and conveyance of powdered materials.

While these two materials might seem similar, they have distinct characteristics that make them suitable for specific applications.

Air Slide Fabric Overview

Air slide fabric, also known as air permeable fabric or aeration pad, is a specialized textile material designed to enable the controlled flow of powdered materials. It consists of multiple layers of woven or non-woven fabric with interconnected channels.

These channels allow air to flow through the fabric, creating a fluidizing effect that helps materials flow smoothly. Air slide fabric is widely used in industries such as cement, chemical, and agriculture for applications like silo discharge, pneumatic conveying, and blending.

Fluidizing Cloth Overview

Fluidizing cloth, on the other hand, is a porous material that is often installed at the base of a container or hopper to aid in the flow of powdered materials. It is typically made from materials like woven polyester or synthetic fibers.

The primary purpose of fluidizing cloth is to introduce air or gas into the powdered material, reducing friction and promoting uniform flow. This technology is commonly employed in applications where consistent flow and discharge are essential.

Key Differences of Air slide fabric vs fluidizing cloth

Composition and Structure

  • Airslide fabric consists of multiple layers of interconnected channels, enabling the passage of both air and material particles.
  • Fluidizing cloth is characterized by its porous nature, allowing air to be introduced into the powdered material for easier flow.

Airflow Mechanism

  • Air slide fabric utilizes the principle of fluidization, where air evenly distributes through the fabric to create a cushioning effect that lifts and fluidizes the powdered material.
  • Fluidizing cloth relies on air introduced from below to aerate the material, reducing interparticle friction and facilitating flow.


  • Air slide fabric is commonly used in applications such as silo discharge, bulk material conveying, and blending due to its ability to maintain consistent material flow.
  • Fluidizing cloth finds its application in hopper discharge, material transport, and other scenarios where ensuring continuous and uniform flow is essential.

Material Compatibility

  • Air slide fabric is versatile and compatible with various powdered materials, including fine and cohesive ones.
  • Fluidizing cloth is effective for materials prone to arching, bridging, or rat-holing, ensuring smooth flow without clogs.


In the realm of bulk powder handling, both air slide fabric and fluidizing cloth play integral roles in ensuring the smooth and efficient movement of materials. While air slide fabric relies on the principle of fluidization through interconnected channels, fluidizing cloth introduces air from beneath the material to promote flow.

The choice between these materials depends on the specific requirements of each application, including material properties, flow consistency, and the prevention of flow issues. By understanding the unique characteristics of air slide fabric and fluidizing cloth, industries can make informed decisions to optimize their bulk powder handling processes.
