Product overview
Fluidization cloth for stable powder flow
Multi-layer fluidizing fabric for air slides, silo bottoms, tankers, vessels and dry bulk powder discharge systems. Airslide fabric is a dense multi-layer woven porous membrane. Low-pressure air passes through the fabric evenly so dry powder can move by gravity with low energy demand and minimal mechanical wear.
Uniform air permeabilityStable air distribution helps avoid local blockage and uneven discharge.
Smooth slidable surfaceThe woven surface supports steady powder flow in air slides and silo floors.
Custom fabricationRolls, strips, discs, cone pieces and drawing-based shapes are available.
Export-ready supportShort lead times, flexible trade terms and mature supply-chain coordination.
Why Shengquan
Built around stable airflow, custom fit and export replacement work
For air slide fabric, credibility comes from repeatable permeability, the ability to match equipment details and practical support before quotation.
Drawing-based fabrication
Rolls, strips, discs, cones and shaped parts can be matched to samples or equipment drawings.
Export-ready support
Technical discussion, sample matching and packaging are prepared for overseas replacement projects.
Supply forms
Ready for standard installation and drawing-based customization
The same fabric structure can be supplied as roll material or converted parts, so buyers can replace existing cloth, maintain silo systems or develop new equipment.
Roll stock
Standard roll supply for air slide conveyors, silo floors and onsite cutting.
Strips and sheets
Cut-to-size strips or panels with width, thickness and air resistance matched to equipment.
Cone and disc parts
Converted pieces for silo bottoms, tankers, vessels and retrofit projects.
Working principle
1
Air chamber supplies low-pressure air
Air is introduced below the fabric layer.
2
Fabric distributes air evenly
The cloth works as a stable porous membrane.
3
Powder becomes fluidized
Dry bulk material gains flowability with low energy demand.
4
Material flows to discharge point
Gravity and airflow help continuous discharge.
Material options
Four fabric families for different operating conditions
Choose by material handled, temperature, abrasion level and surface requirement. Samples or old fabric pieces help us match the closest structure.
Polyester Spun Yarn
Soft, thick and cost-effective construction for general dry powder conveying.
Polyester Filament
Smooth surface and stronger yarn structure for airslide and silo service.
Aramid/Kevlar
High-temperature option where polyester is not enough.
Basalt
For harsh high-temperature and abrasive applications selected by condition.

ThicknessAffects installation fit, wear life and the support required under the fabric.
WidthDetermines whether the fabric can match air slide troughs, silo sectors or converted pieces without extra seams.
Air resistanceHelps match the blower and powder behavior so fluidization is even instead of weak or excessive.
TemperatureDrives material selection between polyester, aramid/Kevlar and basalt options.

FAQ
Common buying questions
How do I choose between polyester, aramid/Kevlar and basalt?
Polyester is usually suitable for normal dry powder conveying. Aramid/Kevlar and basalt are selected when temperature, abrasion or operating conditions are more demanding.
Can you match an old sample or equipment drawing?
Yes. Photos, old fabric pieces, hand sketches and equipment drawings all help us match the closest weave, thickness, width and converted shape.
Can the fabric be supplied as custom parts instead of rolls?
Yes. Roll stock, strips, sheets, discs, cone parts and drawing-based shapes can be prepared according to the installation position.
What information is most useful before quotation?
Material handled, working temperature, width, thickness, length, installation form, quantity and destination country are the most useful details.
