Veolia Flotrex Pleated Filters: Comprehensive Product Guide

Introduction to Veolia Flotrex Pleated Filters

In industrial filtration, selecting the right cartridge filter is critical for ensuring process efficiency, product purity, and equipment protection. Purecowater is proud to distribute Veolia Water Technologies’ Flotrex™ series of pleated cartridge filters. These high-performance filters are engineered with advanced microfiber media technology to deliver exceptional solids-holding capacity and extended service life.

The Flotrex line is designed to cover a vast array of fluid applications, from general water clarification to aggressive chemical filtration. Whether you require absolute particle retention for pharmaceutical applications or nominal filtration for bulk chemicals, the Flotrex family offers a solution. This guide details the specific configurations available, including the Flotrex AP, Flotrex PN, Flotrex HR, and Flotrex GF series.

Product Configurations and Series Breakdown

1. Flotrex AP (Absolute Polypropylene)

The Flotrex AP is an absolute-rated filter constructed from gradient density, thermally-bonded polypropylene microfiber. Designed for high purity, these filters contain no adhesive agents, making them FDA-compliant for food and beverage contact.

• Media: Pure Polypropylene Microfiber
• Rating: Absolute (0.65 to 40 microns)
• Key Features: Low pressure drop, thermally bonded construction, hydrophobic properties.
• Common Applications:
  • Prefiltration and final filtration of chemicals
  • Pharmaceuticals and biological fluids protection
  • High throughput beer filtration

2. Flotrex PN (Nominal Polypropylene)

For cost-effective filtration where absolute precision is less critical, the Flotrex PN offers a nominal rating while maintaining excellent dirt-holding capacity. Like the AP, it is constructed entirely of polypropylene.

• Media: Polypropylene Microfiber
• Rating: Nominal (Cost-effective)
• Key Features: High dirt-loading capacity, broad chemical compatibility, pre-filter capability.
• Common Applications:
  • Filtration of liquid polymers, coatings, and inks
  • General clarification and prefiltration
  • Post carbon bed and DI bed capture

3. Flotrex HR (High Resistance Halar/ECTFE)

The Flotrex HR series is engineered for extreme environments. Made from 100% Halar (ECTFE), these filters provide superior resistance to aggressive chemicals and solvents that would degrade standard polypropylene filters.

• Media: ECTFE (Ethylene Chlorotrifluoroethylene)
• Rating: Absolute (Available in 3.0, 10, and 25 microns)
• Key Features: Resistance to aromatics, halogenated solvents, and ozone (up to 9,000 ppm/hrs).
• Common Applications:
  • Aggressive solvents like toluene, xylene, and benzene
  • Ozonated water filtration
  • Harsh chemical processing

4. Flotrex GF (Glass Fiber)

When high throughput and retention of fine particulate are required in aqueous applications, the Flotrex GF glass microfiber filters are the ideal choice. They are hydrophilic and do not affect product taste, making them suitable for beverages.

• Media: Glass Microfiber
• Rating: Absolute (Meets IBWA 1.0 micron requirements)
• Key Features: Hydrophilic, broad chemical compatibility, low pressure drop.
• Common Applications:
  • Bottled water final filtration
  • Cosmetic oils, gels, and shampoos
  • Beverage clarification

Why Choose Veolia Flotrex Filters?

Veolia’s proprietary manufacturing process thermally welds microscopic fibers into a compact matrix. This construction prevents fiber sloughing and particle unloading, even under pressure surges. Purecowater supplies these filters because they maximize uptime by extending the cycles between change-outs.

Key Advantages:

• Chemical Compatibility: From inert polypropylene to highly resistant ECTFE, there is a material for almost every fluid stream.
• Graded Density: The media layers are designed to capture larger particles on the outer layers and finer particles on the inner layers, maximizing the filter’s volume usage.
• Versatility: Suitable for air, gas, and liquid filtration across multiple industries including Food & Beverage, Microelectronics, and Chemical Processing.
