• Nomex: A polymer fibre that is heat tolerant and fire resistant in nature and is part of the aramid material group. It is suitable for use in applications with hot dust or sparks.
• Teflon (PTFE): Ideal for sticky dust particles and applications where easy cleaning is critical, this non-stick material is.
• Cellulose: Not as durable as synthetic materials, it is sometimes a natural fibre that can be used for dust collection.

These are some of the top materials used for dust filter bags.

How to Select the Best Dust Collector Filter Bag

• Optimal performance and efficient dust collector filter bags are also important for a given application. Here are some key factors to consider:
• The type of dust you’re collecting: We mentioned above that dust particles have different characteristics. Think about the size, shape and how abrasive the dust is.
• The airflow requirements of your dust collector: To function properly, some applications require high airflow. To select a filter bag your dust particles can have enough airflow but with the collected dust particles.
• The operating temperature of your dust collector: The temperature to which the dust collection was conducted had to be sustained by filter bag material.
• The chemical compatibility of the filter bag material: The filter bag material must be resistant to those chemicals if the dust contains chemicals.
• The size and compatibility with your dust collector: Buy the filter bag of the correct size and design for your specific dust collector model. Also, make sure the bag you buy fits the filter adapter of your dust collector model.

These are the steps you need to follow to select the best dust collector filter bag for your needs.
