Airslide fabric is a crucial component in pneumatic conveying systems, facilitating the smooth flow of dry bulk materials. Over time, airborne particles, dust, and contaminants can accumulate on the fabric’s surface, hindering its performance. Proper maintenance and regular cleaning are essential to ensure the fabric’s efficiency and longevity.

Factors Affecting Cleaning Frequency

Several factors determine how often airslide fabric should be cleaned. Understanding these factors will enable us to develop an effective cleaning strategy for the fabric’s optimal performance.

  1. Material Type and Characteristics: The nature of the material being conveyed significantly impacts how quickly the airslide fabric becomes contaminated. Fine, dusty materials, such as cement, fly ash, or powdered chemicals, tend to accumulate more rapidly than coarser substances like grains or pellets.
  2. Conveying Volume and Frequency: Pneumatic conveying systems with high material flow rates and frequent operation are more likely to deposit larger quantities of particles onto the fabric, necessitating more frequent cleaning.
  3. Environmental Conditions: The operating environment plays a vital role in determining the rate of fabric contamination. Dusty or humid environments can lead to faster fabric clogging, requiring more regular cleaning.
  4. System Design and Air Velocity: The design of the conveying system, including the air velocity used to transport materials, influences the amount and type of particles that settle on the fabric. Proper system design can help minimize contamination, leading to longer cleaning intervals.

Recommended Cleaning Schedule

Based on the factors mentioned above, it is essential to establish a cleaning schedule that strikes the right balance between maintaining fabric efficiency and avoiding excessive downtime for cleaning. A suggested cleaning schedule is as follows:

  1. Daily Visual Inspection : Perform a daily visual inspection of the airslide fabric to identify any visible signs of clogging or material buildup. Address any minor issues immediately to prevent further accumulation.
  2. Weekly Cleaning : For pneumatic conveying systems operating continuously or frequently, a weekly cleaning routine is recommended. Use compressed air or a low-pressure blower to remove loose particles and dust from the fabric’s surface.
  3. Monthly Deep Cleaning : Conduct a more thorough cleaning once a month. This involves shutting down the system, removing the airslide fabric, and using appropriate cleaning agents to dissolve and remove stubborn deposits.

Three key points for choosing the right cleaning method

Selecting the appropriate cleaning method is vital to prevent damage to the airslide fabric while effectively removing contaminants. There are several cleaning techniques available:

  1. Compressed Air Cleaning : Compressed air is a simple and effective method for regular cleaning. It dislodges loose particles and prevents them from settling on the fabric. However, it may not be sufficient for deep cleaning.
  2. Mechanical Cleaning : Mechanical cleaning methods, such as brush cleaning, can be used to agitate and remove stubborn deposits from the fabric. This method is suitable for localized cleaning but should be used with caution to avoid fabric damage.
  3. Chemical Cleaning : Chemical cleaning agents can be employed for monthly deep cleaning. These agents break down and dissolve material deposits, restoring the fabric’s permeability. It is crucial to use chemicals that are compatible with the fabric material.

Top 3 Importance of Regular Maintenance

Regular maintenance and cleaning of airslide fabric offer several benefits, including:

  1. Optimized System Efficiency: Clean airslide fabric ensures smooth material flow, minimizing the risk of blockages and system downtime. This leads to improved overall system efficiency and reduced operating costs.
  2. Extended Fabric Lifespan: Proper cleaning and maintenance help extend the life of the airslide fabric, reducing the need for frequent replacements and saving on replacement costs.
  3. Reduced Material Contamination: A clean fabric prevents cross-contamination of materials, ensuring the purity and integrity of the conveyed products.

Additional Tips for Effective Cleaning

  1. Safety First: Always follow safety procedures while cleaning the airslide fabric. Shut down the system and ensure that all moving parts are locked out to prevent accidents.
  2. Test Cleaning Agents: When using chemical cleaning agents, conduct a small test on a sample piece of fabric to ensure compatibility and to assess the effectiveness of the cleaning agent.
  3. Regular Fabric Inspection: Regularly inspect the airslide fabric for signs of wear, tears, or other damage. Timely repairs or replacements can prevent costly breakdowns.
  4. Training for Personnel: Train personnel on proper cleaning techniques and safety protocols to ensure efficient and safe cleaning practices.
  5. Monitor Cleaning Results: After cleaning, monitor the fabric’s performance to evaluate the effectiveness of the chosen cleaning method and adjust the cleaning schedule as needed.


In conclusion, the cleaning frequency of airslide fabric depends on various factors such as material type, conveying volume, environmental conditions, and system design. Implementing a regular cleaning schedule, along with appropriate cleaning methods, will enhance the fabric’s efficiency and longevity. By maintaining a clean airslide fabric, pneumatic conveying systems can operate at their full potential, ensuring seamless and efficient material transport.

Maintaining a clean airslide fabric is essential for the smooth functioning of pneumatic conveying systems. By considering material type, conveying volume, environmental conditions, and system design, operators can determine an appropriate cleaning frequency.

Regular maintenance and cleaning not only improve system efficiency and reduce downtime but also extend the fabric’s lifespan. Implementing the right cleaning methods and adhering to safety procedures will ensure that the airslide fabric continues to perform optimally, facilitating the efficient transportation of dry bulk materials.
