Abstract

The present disclosure generally relates to filter media including glass fibers. The fiber characteristics (e.g., composition, dimensions) are selected to impart the desired solubility, filtration and mechanical properties so that the filter media may be used in the desired application.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A filter media comprising:
 a fiber web including a plurality of glass fibers having a BaO content of greater than 7.2 wt % and an alumina content of less than 3.0 wt %.   
     
     
         2 . The filter media of  claim 1 , wherein the glass fibers have an average diameter of less than 3 microns. 
     
     
         3 . The filter media of  claim 1 , wherein the glass fibers have a B 2 O 3  content of between 5.0 wt % and 15.0 wt %. 
     
     
         4 . The filter media of  claim 1 , wherein the glass fibers have a B 2 O 3  content of between 8.0 wt % and 15.0 wt %. 
     
     
         5 . The filter media of  claim 1 , wherein the BaO content is less than 20.0 wt %. 
     
     
         6 . The filter media of  claim 1 , wherein the BaO content is between 8.0 wt % and 20.0 wt %. 
     
     
         7 . The filter media of  claim 1 , wherein the glass fibers have an alumina content of between 0.5 wt % and 3.0 wt %. 
     
     
         8 . The filter media of  claim 1 , wherein the glass fibers have an alumina content of less than 2.5 wt %. 
     
     
         9 . The filter media of  claim 1 , wherein the glass fibers have an alumina content of between 1.0 wt % and 2.5 wt %. 
     
     
         10 . The filter media of  claim 1 , wherein the glass fibers have a total alkali oxide content of between 10.0 wt % and 25.0 wt %. 
     
     
         11 . The filter media of  claim 1 , wherein the glass fibers have a Na 2 O content of between 6.0 wt % and 25.0 wt %. 
     
     
         12 . The filter media of  claim 1 , wherein the glass fibers have a K 2 O content of between 0.5 wt % and 8.0 wt %. 
     
     
         13 . The filter media of  claim 1 , wherein the glass fibers have a total alkaline earth content of less than 20.0 wt %. 
     
     
         14 . The filter media of  claim 1 , wherein the glass fibers have a MgO content of between 0.1 wt % and 8.0 wt %. 
     
     
         15 . The filter media of  claim 1 , wherein the glass fibers have a CaO content of between 0.1 wt % and 15.0 wt %. 
     
     
         16 . The filter media of  claim 1 , wherein the glass fibers have a silica content of between 45.0 wt % and 80.0 wt %. 
     
     
         17 . The filter media of  claim 1 , wherein the glass fibers have a ZnO content of between 1.5 wt % and 8.0 wt %. 
     
     
         18 . The filter media of  claim 1 , wherein the fiber web exhibits a Kdis after 28 days of between 95 ng/hour/cm 2  and 200 ng/hour/cm 2 . 
     
     
         19 . The filter media of  claim 1 , wherein the glass fibers have an average diameter of greater than 0.1 micron. 
     
     
         20 . A filter element comprising the filter media of  claim 19 . 
     
     
         21 . A filter media comprising:
 A fiber web including a plurality of glass fibers having a BaO content of greater than 7.2 wt %, an alumina content of less than 10.0 wt % and a B 2 O 3  content of greater than 5.0 wt %.
