PolyKeyTM filter cartridges are manufactured from melt-blown and spun-bonded pleated polypropylene media, ensuring a highly efficient media with excellent particulate removal as well as low pressure drops. Features and Benefits Excellent Chemical Compatibility High quality pleated polypropylene construction meets FDA CFR Title 21 criteria for the processing of liquid foods, and allows for usage with many aggressive chemicals. Variety of End Caps PolyKeyTM cartridge filters are available with a wide variety of end cap fittings, which can easily be retrofitted into many existing housings. High-Efficiency Design The high-efficiency design ensures a cost-effective solution when used as a pre-filter, extending the life of more costly final filters, saving money and reducing downtime.
