Powder conveying is a critical process in industries such as food, pharmaceuticals, and chemical manufacturing. Among the various methods available, air slide fabric stands out as an efficient and gentle solution.

Air Slide Fabric: A Primer

Understanding Air Slide Fabric

Air slide fabric, also known as air gravity conveyor fabric, is a porous material used for pneumatic conveying of powders and granular materials. It operates on the principle of fluidization, where a controlled flow of air passes through the fabric, suspending and carrying the powder particles along the conveying path.

The Mechanics of Fluidization

Fluidization occurs when air passes through the pores of the fabric, creating an upward airflow that lifts and fluidizes the powder. This phenomenon reduces friction and allows for a more controlled and uniform flow of material.

Advantages of Air Slide Fabric in Powder Conveying

Gentle Conveying

Air slide fabric’s fluidization mechanism ensures that powder particles are transported without physical contact. This gentle conveying minimizes the risk of particle degradation or damage, making it ideal for delicate and friable materials.

Reduced Segregation

One common challenge in powder conveying is particle segregation, where different-sized particles separate during transport. Air slide fabric’s controlled fluidization helps maintain a consistent mixture, reducing the risk of particle segregation.


Air slide fabric is versatile and suitable for a wide range of powdered materials, including fine powders and granules. This adaptability makes it a preferred choice for industries handling diverse powders.
