Nanofiber Air Filters

Baldwin ‘Extreme Performance’ nanofiber filters

Baldwin Filters has released its new line of Extreme Performance heavy-duty air filters featuring its patented ProTura nanofiber technology. These filters fit common agricultural, mining and construction applications where high dust content is an issue.

The new filters have fibers with an average diameter of 90nm (a nanometer is one billionth of a meter). These ultra-fine fibers bonded to cellulose media provide unequalled performance in removing submicron contaminants, Baldwin says.

The result is better engine protection and longer filter service life.

With the ProTura nanofiber media, the fine contaminants tend to load on the media surface resulting in higher initial contaminant removal efficiency and lower flow restriction, according to Baldwin. Through normal use, the submicron particles tend to cake on the surface of the media, then fall to the bottom of the housing where they can be removed by the dust ejector, increasing the filter’s contaminant removal capacity.
