Prefiltration Membranes

Request Information

Add an upstream prefilter to extend the lifespan and throughput of your filter. Organic solvents are most often prefiltered through polypropylene prefilters. Aqueous solutions are most widely clarified with glass fiber prefilters with binder resin, which have superior wet strength and can collect dirt from heavily contaminated liquids.
