COLBACK FOR FILTER MEDIA
WITH SHARP AND STABLE PLEATS

Filter producers around the globe apply Colback as carrier material in the manufacture of activated carbon filter media. And they use the spunbond nonwoven as support layer for particle filter media. Thanks to its high dimensional and thermal stability the nonwoven can be easily pleated. It adds stiffness to the filter medium. Pleats created with Colback as air filter carrier are sharp and stable. The uniform open structure of thermally bonded endless bi-component filaments guarantees optimal air permeability.

Thanks to their high air permeability and contribution to pleat stability Colback filter carriers provide a significant reduction in pressure drop. This is a huge benefit in the finished product: Why? Because low pressure drop increases the expected life time of the filter element. And it allows the user of the filter to achieve significant energy savings. This makes our clients’ products more cost-effective. If you consider to use Colback nonwoven filter fabrics, you can select the right nonwoven from a wide range of different polymer configurations, weights and colors. And we can tailor the roll width and length to suit your individual process requirements and settings.

Time and again, filter manufacturers have confirmed that Colback helps them improve the efficiency of their manufacturing process. And that the spunbond nonwoven enhances the performance of their finished filter elements. Examples of characteristics, which make that Colback outperforms alternative air filter carriers include:

• More predictable and consistent performance
• Improved ease of processing
• Superior stiffness and stability facilitating sharp pleats
• Allows higher pleats
• Enhances the air permeability of filter elements
• Reduces pressure drop
• Facilitates waste reduction and energy savings
