Surface loading excels over depth loading UAS ProTura® Nanofiber filters 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...
