8 Key Points That Affect Air Slide Fabrics
The weight of air slide fabrics and the type of materials have great impacts on the tensile strength, elongation, abrasion resistance, air permeability, Dimensional stability, and thickness. Nevertheless, the needle’s penetration depth has little impact on the same properties.
- Increasing the fabric weight leads to an increase the tensile strength, abrasion resistance, Dimensional stability, and thickness.
- Increasing the air slide fabric for cement weight leads to a decrease the air permeability and elongation.
- Increasing the needless penetration depth leads to an increase the tensile strength, abrasion resistance, and dimensional stability.
- Increasing the needle’s penetration depth decreases the elongation, air permeability, and thickness.
- The fabrics made of polyester and Nomex have higher tensile strength abrasion resistance air permeability dimensional stability and thickness than the Fabrics made of 100% polyester.
- The fabrics made of polyester have a higher elongation at break than the fabrics made of polyester and Nomex. Whenever the elongation at break of air slide fabrics decreased the more it is suitable for usage.
- The fabrics in the length direction recorded higher tensile strength and elongation than the fabrics in the width direction.
- The fabrics made of (85%polyester+15%nomex) are better in the required properties as the air slide fabrics than the fabrics made of 100% polyester.

The concept of fluidization
Fluidizing solid materials is the method of introducing pressurized air into the material, which causes the particles to separate and move. Once the particles are separated by these small gaps of air, the amount of friction between them is greatly reduced, and this allows the solid material to flow
as if it were a fluid.
material characteristics
Most powdered and small grain materials can be fluidized and moved using an air slide conveyor. The basic requirements are that the material is dry and consistent, meaning no lumps or large particles. The particle size must be similar to table salt (500 microns) or smaller. Particles larger than that will have trouble being fluidized.
fluidizing fabric
The air slide fabric we typically use for air slide conveyors is woven polyester, 6mm thick. This material works well for all common conveyor environments and situations.
Should your conveyor need to run through harsh environments
(namely high temperature) will determine if a different fabric will need to be used
Top 6 keys for air slide conveyor design
- Air slide conveyors can be used in a single straight run, but are equally as effective when used in large systems. Through the
- use of turn boxes, conveyors can easily change directions, merge, or split without the need for powered conveyors or diverters.
- Manual or powered shut-off gates can be integrated into any point of the system to control flow.
- The maximum range of the conveyors is limited only by the height of the
- source. Conveyors require a minimum of a 5-degree drop angle to function properly. A 10-degree angle is recommended for most applications.
- For every 20 ft of horizontal run, a 10-degree conveyor will drop 3 and a half feet.
