Ahlstrom Grade 237 is a high absorbency grade that is twice as thick as Grade 642 with similar particle retention. The extra thickness gives higher wet strength and loading capacity which enables more precipitate to be held without clogging the filter. This low ash grade contains more than 95% super refined alpha-cellulose and linter fibers. Filtration rate: medium. Retention: 6 microns.
