Polyester Air Slide Fabric for Pneumatic Conveying
Air slide conveyors use low-pressure air forced through a permeable fabric membrane to fluidize dry bulk powders, allowing them to flow by gravity along a slightly inclined trough. This gentle, energy-efficient method moves hundreds of tons per hour with minimal wear, no moving parts, and very little maintenance.
We carry two categories of air slide fabric: Polyveyor® needled polyester (which doesn't require stretching before installation and won't unravel when cut) and solid woven polyester in three permeability grades. Both are found in air gravity conveyors, silos, rail cars, barges, ships, and tank trailers designed for the storage and transport of dry bulk powders.
Polyveyor® Needled Polyester Air Slide Fabric
Needled polyester air permeable fabric designed specifically for air gravity conveyors. No stretching required prior to installation. Won't unravel when cut or punched.
Solid Woven Polyester Air Permeable Fabric
100% woven polyester air permeable fabrics in three permeability grades for pneumatic conveyors, silos, rail cars, barges, ships, and tank trailers.
How Air Slide Conveyors Work
Air slide systems use a simple, reliable principle to transport dry bulk powders with minimal energy and virtually no moving parts.
💨
Fluidization
Low-pressure air is forced upward through the permeable fabric membrane, suspending dry powder particles and creating a fluid-like state that allows the material to flow freely.
⚡
Energy Efficient
With no belts, chains, or motors to power, air slides consume significantly less energy than mechanical conveyors. Only a low-pressure blower is needed to move hundreds of tons per hour.
🔧
Low Maintenance
No moving parts in the conveying section means minimal wear and virtually zero maintenance. The fabric is the only consumable component and installs quickly without stretching (needled polyester).
🏭
Common Applications
Cement plants, mining operations, chemical processing, agriculture (grain/flour), bulk terminal unloading, silo discharge, rail car unloading, barge/ship unloading, and tank trailer discharge.
Needled vs. Woven Polyester — Which Is Right?
NP
Needled Polyester (Polyveyor®)
No pre-stretching required before installation. Won't unravel when cut or punched. Available in 0.5 CFM and 1.5 CFM permeability, plus Kevlar high-temp (500°F continuous). Provides several advantages over traditional woven air permeable fabrics.
WP
Solid Woven Polyester (WP Series)
100% woven polyester construction in three permeability grades: WPLP (Low), WPMP (Medium), WPHP (High). Traditional construction with excellent strength and durability. Max continuous temperature 225°F / intermittent 275°F.
