RW Prefilters

RW prefilters can be used to remove contaminants from a variety of liquids and gases. The filters have a high dirt holding capacity and a low pressure drop, which makes them ideally suited for reducing contaminant levels in advance of sterilizing -grade filters.

Whereas traditional prefilter materials contain asbestos or fiberglass, RW filters are made from non-shedding materials. The filters retain contamination on the surface of the cellulose membrane.
