Surface Loading Excels over Depth Loading

Oct 08, 2016

China Chentai Nanofiber filters media feature an ultra-thin surface layer of synthetic fibers so extremely fine, they are measured in nanometers, or fractions of a micron. The layer provides excellent surface-loading capabilities due to the nano-size interfiber pores that make up their web-like surface coating. ProTura Nanofiber, therefore, acts as a shield to prevent submicron sized particles from entering and becoming embedded within the filter’s substrate media. As a result, dust particles are easily released from the surface layer while the media substrate remains clean leading to fewer cleaning cycles required, lower pressure drop, reduced outlet emissions and increased filter life.

Commodity cartridge filters allow particulate to embed deep within the substrate, making them more difficult to clean. Unlike ProTura Nanofiber cartridges, these depth-loading filters have large spaces or pores within their base media fibers which allow particles to penetrate deep within the media substrate increasing pressure drop. Subsequently, they plug at a faster rate requiring more frequent cleaning which leads to increased abrasion, wear and reduced filter life. Some commodity filters include surface treatments but their coatings form layers 100 times or more thicker than Chentai Nanofiber filter media thus creating additional depth-loading layers which further decreases commodity filter life.
