	Woven Fabrics for Pneumatic Conveying (Airslide® Fabrics)
	Download PDF version (84KB)

Solid woven fabrics are used as a porous media on pneumatic conveyors and silos to handle powdered or granular materials such as cement, flour, fly ash etc. They are also used to assist the discharge of silos and road/rail trucks used to transport such materials.
There are two main fabrics used in this application for normal conditions, Cotton or Polyester. Both types are of solid woven construction and are porosity tested during manufacture to ensure conformance to the permeability required. Traditional Cotton fabrics have been used for many years in the cement industry, and are still available in a limited number of widths with woven selvedges. Polyester fabrics are not affected by moisture as are the Cotton belts, and are available cut to width with heat sealed edges. Two anti-static grades are also available. For special applications such as high temperature other materials are manufactured using modern hi tech fibres such as Nomex® and Kevlar®. All of our Airslide fabrics are available in open rolls, cut to size pads or fabricated shapes such as cones.

	Spen-Tex Woven Aeration Hose
	Download PDF version (63KB)

Bensons Spen-Tex Aeration Hose is designed to aid the discharge of bulk powders from storage silos, from road and rail tankers and from powder transport barges.
The hose is tubular woven using 100% synthetic yarns and is coated with yellow polyurethane on one side to give additional abrasion resistance and to restrict air flow through the coated side, ensuring that the air passes mainly through the uncoated surface. Careful positioning of the hose will therefore control where aeration occurs.
The hose is lightweight and flexible, easy to store, transport and install and is resistant to ageing and weathering.
Standard Roll lengths:     30m, 50m, 100m
Sizes Available:
Standard Size Shaded Yellow Made to Order Sizes Shaded Grey     Internal Dia. Flat Width 58 92 71 113 75 120
Permeability: Nominal results
Inlet Pressure Ltr./Sq.M./Sec 0.01 bar 4.0 0.02 bar 5.5 0.03 bar 6.0
Temperature Range*
-30°C to +80°C (Constant)
-30°C to +150°C (intermittent)
* The PU coating will soften and gradually degrade above 80°C and aeration will start to occur through the PU after a period of time.
