Fluitex® Woven Fabrics for Pneumatic Conveying
(Airslide® Fabrics)

 

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 four main fabrics used in this application for normal conditions, Cotton or Polyester, Nomex® and Kevlar®.

Solid woven construction and 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.

Modern Hi-tech fibres like Nomex® and Kevlar® are used for demanding applications where high temperature and/or aggressive chemicals are involved. Such applications are found in power generating plants, and particularly in the expanding Green Energy industry sectors: (EWF) Energy from Waste), CHP (Combined Heat & Power), RDF (Refuse Derived Fuel), ERF (Energy Recovery Facilities), APC (Air Pollution Control residue), and IBA (Incinerator Bottom Ash.

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

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.Spen-Tex Aeration Hose

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.Spen-Tex Aeration Hose

The hose is lightweight and flexible, easy to store, transport and install and is resistant to ageing and weathering.Spen-Tex Aeration Hose

Standard Roll lengths:    30m, 50m, 100m

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.
