Airslide technology, also known as fluidized conveying, is a widely used method for transporting bulk materials in various industries. Its ability to move powders and granular materials efficiently has made it a popular choice for handling materials in many processes.

However, like any technology, airslide systems have certain limitations that can impact their performance and effectiveness.

Understanding Airslide Technology

Airslide technology utilizes low-pressure air to fluidize and suspend powdered or granular materials on a fabric conveyor system. The process involves passing air through a porous fabric medium, which allows the material to flow like a fluid, eliminating the need for mechanical conveyors.

Advantages of Airslide Technology

Before delving into the limitations, it’s essential to recognize the advantages that have made airslide technology popular:

  1. Efficient Material Handling: Airslide systems offer efficient and continuous material flow, reducing the risk of blockages and material buildup during transportation.
  2. Gentle Handling: The fluid-like movement of materials in airslide conveyors ensures gentle handling, preventing degradation and maintaining material integrity.
  3. Dust Containment: Airslide technology minimizes dust generation during material transfer, creating a cleaner and safer working environment.
  4. Minimal Maintenance: With fewer moving parts, airslide systems require less maintenance compared to traditional mechanical conveyors.

Top 5 Limitations of Airslide Technology

While airslide technology provides several advantages, it also comes with certain limitations that should be considered in specific applications:

  1. Limited Conveying Distance: One significant limitation of airslide technology is its restricted conveying distance. For long-distance material transportation, airslide systems may not be the most practical option due to pressure drop and energy consumption issues.
  2. Material Limitations: Airslide systems are most effective with fine, free-flowing materials. Handling coarse or heavy materials can be challenging, as they may not fluidize or flow as easily.
  3. Sensitivity to Moisture: Moisture in the material can disrupt the fluidization process in airslide conveyors, causing material flow issues and potentially leading to blockages.
  4. Airslide Fabric Wear: The fabric medium used in airslide systems can experience wear and tear over time, which may require regular replacement to maintain efficient operation.
  5. Temperature Sensitivity: Extreme temperature variations can affect the performance of airslide technology, especially in outdoor or high-temperature environments.

Top 5 Strategies to Overcome Limitations

Manufacturers and engineers have developed several strategies to address the limitations of airslide technology, ensuring its effectiveness in diverse applications:

  1. Intermediate Transfer Points: To overcome the limited conveying distance, intermediate transfer points can be introduced along the conveying route, effectively breaking up the journey and reducing pressure drop.
  2. Material Pre-Treatment: For materials with poor fluidization properties, pre-treatment processes such as drying or size reduction can be implemented to enhance flowability and optimize airslide performance.
  3. Moisture Control: Proper moisture control measures, such as drying the material before conveyance or using dehumidifiers in the system, help prevent moisture-related issues during transportation.
  4. Fabric Selection and Maintenance: Utilizing high-quality and durable airslide fabrics and implementing regular maintenance schedules can extend the life of the fabric and ensure smooth operation.
  5. Insulation and Climate Control: Insulating airslide systems and implementing climate control measures can mitigate the impact of temperature fluctuations and maintain consistent performance.


Air slide technology has revolutionized material handling in various industries, providing efficient and dust-free transportation for a wide range of bulk materials. However, it is essential to acknowledge the limitations that come with this technology, such as restricted conveying distance, material limitations, and sensitivity to moisture and temperature.

By employing suitable strategies, such as intermediate transfer points, material pre-treatment, and proper fabric selection and maintenance, these limitations can be effectively overcome, allowing airslide technology to continue as a reliable and valuable tool in bulk material handling applications.

As technology advances and industry demands evolve, engineers and manufacturers will continue to innovate and improve airslide systems, expanding their capabilities and pushing the boundaries of efficient material handling in the future.
