FM-BB-20-50 Flow-Max filter cartridges outperform other pleated elements because our highperformance filter media is systematically produced using 100% synthetic fibers, with no binders or additives to leave a residue, foam or contaminate. Increased dirt holding capacity; longer life; fewer cartridge replacements needed; and reduced filtration costs, compared to other pleated cartridge suppliers. Flow max filters may take up to two weeks to receive from the order date.
