- Precision Air Permeability
- Chemical & Environmental Resistance
- Eco-Efficient Performance
Core Functions
Aramid Air Slide Fabric is a high-performance conveying solution that utilizes aramid fibers (such as Nomex® or Kevlar®) to enable efficient, low-energy powder transport. Its key features include exceptional heat resistance (withstanding continuous temperatures up to 220°C), flame retardancy, and chemical resistance, making it ideal for demanding industries like cement, metals, and chemicals. The fabric’s precision air permeability ensures uniform material flow at low pressure (0.1–0.3 bar), while its anti-static and wear-resistant properties enhance safety and durability. Compared to mechanical conveyors, it reduces energy consumption by 30–50% and prevents material contamination, offering a clean, reliable alternative for powder handling.

Working Principle of Aramid Air Slide Fabric
Aramid air slide fabric operates by introducing low-pressure air (0.1-0.5 bar) through the bottom air chamber, which uniformly penetrates the specially woven aramid permeable fabric to form a stable air cushion layer on the surface. This fluidizes powdered materials into a “gas-solid mixed phase,” allowing them to slide naturally along the 4°-10° inclined chute under gravity. The high-temperature resistance of aramid fibers (220°C continuous/250°C peak) ensures stable operation in high-temperature environments. Compared to mechanical conveying systems, this air cushion conveying method saves 30-50% energy with no moving part wear, making it particularly suitable for high-temperature powder conveying in industries such as cement and metallurgy.
