World Class Filtration Solutions


A range of high-quality nominally-rated pleated polypropylene cartridge filters, suitable for challenging filtration environments, including chemical processing, process water and food and beverage.

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.

  • Outer Guard in a Single Module
    The cartridge is held together within one singular outer guard, providing a more robust structure compared to welded alternatives.

  • Wide Range of Options
    Available in both standard diameter (2.75” / 70mm) and wide diameter (4.5” / 114mm), and in a range of lengths from 5-40” (127-1,016mm).
