Flotrex Pleated Microfiber Filters

High-performance cartridge filters with microfiber media

Flotrex pleated cartridge filters use microfiber media technology to deliver high solids-holding capacity and extended service life. Available in multiple materials for diverse applications, these filters offer both nominal and absolute filtration ratings ranging from 0.2 to 40 microns.

 

Overview

Hydrophilic Filters - “affinity to water”

Used for aqueous (water-based) systems

Polypropylene Microfiber Filter: Flotrex AP - Absolute

Polypropylene Microfiber Filter: Flotrex AP Absolute

The Flotrex AP  is a pure polypropylene (PP) microfiber filter offering absolute particle retention through layered melt-blown media. Features include hydrophobic properties, FDA food-grade compliance, absolute ratings for air/gas/liquid filtration (0.65 - 40 microns), low pressure drop, broad chemical compatibility, and multiple sterilization options including steam, autoclave, or chemical sanitization.

Industries and Applications

Certification and Compliance

  • ISO 9001:2015 certified processes

Polypropylene Microfiber Filter: Flotrex PN - Nominal

Polypropylene Microfiber Filter: Flotrex PN Nominal

Flotrex PN filters are cost-effective, nominal-rated cartridges made entirely of polypropylene (PP), featuring thermally bonded construction without adhesives. These pre-filters offer excellent dirt-holding capacity, reliable particle retention, and broad chemical compatibility. They can be sterilized by steam, autoclave, or chemical sanitization, and are manufactured in the USA.

Industries and Applications

  • Filtration of liquid polymers, coatings, and inks 
  • Filtration of bulk chemicals 
  • General clarification an prefiltration 
  • Filtration of viscous streams 
  • Beer trap filtration 
  • Post carbon bed and deionization (DI) bed filtration 
  • Prefiltration to protect expensive final filters

ECTFE Microfiber Filter: Flotrex HR

ECTFE Microfiber: Flotrex HR

Flotrex HR filters are all-Ethylene Chlorotrifluoroethylene (ECTFE), absolute-rated cartridges designed for extreme chemical environments. Made from industrial-grade ECTFE, they provide superior solvent resistance and 99.9% filtration efficiency (ASTM F795/F661 certified). These hydrophobic filters offer high flow rates, excellent chemical compatibility including aromatics, halogenated solvents, organics, and ozone resistance (9,000 ppm/hrs). Suitable for both pre- and final filtration, they can be sanitized with chemicals like ozonated water but cannot be autoclaved or steam sterilized. Made in USA.

Hydrophobic Filters - “adverse to water”

typically used for vent filtration or harsh chemical environments

Glass Fiber Filter: Flotrex GF

Glass Fiber Filter: Flotrex GF

Flotrex GF filters use absolute-rated glass microfiber media that won't affect product taste. These hydrophilic filters feature low pressure drop and broad chemical compatibility, making them ideal for final filtration, particularly in bottled water applications where they meet International Bottled Water Association (IBWA) 1.0-micron absolute rating requirement. They can be sterilized by steam, autoclave, or chemical sanitization.

Chemical Compatibility 

chemical compatibility 

Veolia manufactures a series of melt-blown polypropylene depth filters as well as pleated filters made from a variety of microfiber and polymeric membrane materials. This wide array of cartridge media and elastomer materials ensure the right filter and configuration for your application. Veolia filter cartridges are designed and manufactured for their resistance to a wide range of chemical solutions.

How to Use the Chemical Compatibility Table: 

R = Resistant. No significant change was observed in flow rate or bubble point of the membrane following 48 hours exposure to the test fluid at 77°F (25°C). 

LR = Limited Resistance. Moderate changes in physical properties or dimensions of membrane were observed. Filter may be suitable for short term, noncritical use. 

NR = Not Resistant. The membrane is basically unstable. Extensive shrinkage or swelling of the membrane may occur. The filter may gradually weaken or partially dissolve after extended exposure. 

O = Insufficient Data. Testing on your own solution is recommended. 

chemical resistance 

Veolia polypropylene cartridge filters are made of pure polypropylene, an inert material which is compatible with a wide range of chemicals. No resins, binders, antistatic agents, or other materials are added during the manufacturing process. Veolia polypropylene cartridge filters are manufactured with a proprietary melt-blown microfiber technology. This unique process thermally welds microscopic fibers of polypropylene into a compact matrix which resists fiber sloughing and particle unloading into the filtrate, even under extreme mechanical and chemical actions. The manufacturing operation is precisely controlled to yield cartridge filters with consistent micron ratings and true graded density for high particle retention and longer life.
