Bag/Sock Filter Cartridges: Our Bag Replacement Filter (Bullet Series) has changed the way that bag filtration vessels are viewed and used. These filters utilize a proprietary string winding approach to create layers of filtration 1.5” deep. This approach traps and removes a larger volume of particles and contaminants than bags/socks. In some applications customers have captured as much as 15 pounds of particulates. Gone are the days of replacing and disposing of bags/socks multiple times per day or week and sketchy performance in capture. These filters are a direct replacement to #2 filter bags and fit directly into all major manufacturer baskets.

Pleated Filter Alternatives: Our string wound cartridge filter media provide more depth to trap and remove a larger volume of particulates than their pleated competitors. With flow rates up to 500 GPM our cartridges will outperform standard filter elements by multiples of 5 or more! Our customers experience a better quality of filtration, reduced downtime, maintenance and labor cost. These filter elements replace cartridges from Pall, 3M, FTC, Fil-Trek, Parker, Shelco, Jonell, PecoFacet, Global and others. Call us today to see the improvements yourself!
