Airslide fabric, also known as fluidization fabric or aeration pad, is a versatile material widely used in industrial applications for pneumatic conveying of powdered and granular materials. Understanding the appropriate temperature range is essential for optimizing efficiency and ensuring the material’s longevity in various industrial processes.

Temperature control plays a vital role in the effective functioning of airslide fabric. The recommended operating temperature is crucial for preventing premature wear and tear, clogging, and potential failure of the fabric. The temperature influences the physical and mechanical properties of the fabric, which directly impact its functionality and efficiency in pneumatic conveying systems.

Top 4 Factors Affecting Airslide Fabric Performance

Before diving into the specific recommended temperature range, let’s explore the factors that affect airslide fabric performance:

  1. Material Composition: Airslide fabrics are typically made from synthetic fibers, such as polyester or polyamide. The choice of materials affects the fabric’s resistance to temperature variations.
  2. Air Permeability: The fabric’s ability to allow air to pass through is vital for maintaining the flow of powdered materials in pneumatic conveying. Temperature changes can influence the fabric’s porosity and permeability.
  3. Mechanical Strength: High temperatures can compromise the mechanical strength of the fabric, leading to potential damage and decreased lifespan.
  4. Material Being Conveyed: The type of material being transported through the airslide fabric also influences the operating temperature requirements. Different materials may have specific temperature constraints that need to be considered.

Recommended Operating Temperature Range

The ideal operating temperature for airslide fabric is typically within the range of 50°C to 70°C (122°F to 158°F). This temperature range ensures optimal performance and longevity. Operating within this range helps maintain the fabric’s structural integrity and prevents issues such as fabric shrinkage, deformation, or melting.

Top 3 Effects of Low Temperatures

Exposing airslide fabric to temperatures below the recommended range can lead to several adverse effects:

  1. Reduced Air Permeability: Low temperatures can cause the fabric to contract, reducing its air permeability. This can lead to material flow disruptions and clogging in the pneumatic conveying system.
  2. Brittleness: At low temperatures, the fabric may become brittle, increasing the risk of cracks and tears, especially during installation or handling.
  3. Inefficient Conveying: Inadequate air permeability results in inefficient conveying, leading to increased energy consumption and reduced productivity.

Top 3 Effects of High Temperatures

Conversely, subjecting the airslide fabric to temperatures above the recommended range can result in the following issues:

  1. Loss of Mechanical Strength: High temperatures can weaken the fabric’s fibers, diminishing its mechanical strength and tensile properties.
  2. Fabric Deformation: Prolonged exposure to high temperatures can cause the fabric to deform, leading to uneven airflow and suboptimal material flow.
  3. Reduced Lifespan: Elevated temperatures accelerate wear and tear, reducing the fabric’s lifespan and increasing maintenance costs.

The Impact of Material Type on Operating Temperature

Different airslide fabrics are designed for various applications and materials. The choice of material depends on factors such as temperature resistance, chemical compatibility, and abrasion resistance. Here are some common materials and their impact on the recommended operating temperature:

  1. Polyester and Polyamide: Polyester and polyamide fabrics are widely used due to their moderate temperature resistance and cost-effectiveness. They are suitable for handling materials within the recommended temperature range.
  2. Polypropylene: Polypropylene fabrics have a lower temperature resistance than polyester and polyamide but are still appropriate for conveying materials at temperatures up to 65°C (149°F).
  3. PTFE-coated: PTFE-coated fabrics offer higher temperature resistance and can handle materials at temperatures between 70°C and 90°C (158°F to 194°F). These fabrics are preferred for applications involving hot materials or extreme operating conditions.

Tips for Maintaining Airslide Fabric

  • Regularly inspect the fabric for signs of wear, tear, or damage.
  • Clean the fabric regularly to prevent material buildup that can affect permeability.
  • Avoid exposure to temperatures outside the recommended range to maintain the fabric’s integrity.
  • Select the appropriate fabric material based on the conveyed material and temperature requirements.
  • Handle the fabric with care during installation and maintenance to prevent accidental damage.


Maintaining the recommended operating temperature range is crucial for maximizing the performance and lifespan of airslide fabric in pneumatic conveying systems. Choosing the right fabric material and implementing proper temperature control measures ensure smooth material flow, reduce downtime, and enhance overall operational efficiency.

By adhering to the suggested guidelines and understanding the impact of temperature on airslide fabric, industries can achieve seamless and reliable material handling processes.
