Purtrex™ Depth Filters
 

 

Longer Life & Fewer Changeouts

Osmonics has extended its patented* blown microfiber technology to meet the market requirements for a pure polypropylene depth filter with exceptional dirt-holding capability. This translates to longer life and fewer changeouts than existing string-wound or resin-bonded filters. The resulting product, Purtrex, is an exceptional value for general applications where long-life, high purity and low changeout frequency is required.

 

High Dirt-Holding Capacity

  • True-graded density captures particles throughout entire filter depth
  • High dirt-holding capacity means longer life and fewer changeouts which translates to money saved
  • Lower density at the surface of the filter with progressively higher density towards the center
  • No surface blinding, which reduces flow and increases filter changeouts

 

 

Pure Polypropylene Construction

  • Thermally bonded microfibers
  • Contains no wetting agents, solvents, antistatic agents or binders
  • Wide chemical compatibility
  • Incinerates to trace ash for easy disposal
  • Meets the requirements of the FDA for food and beverage contact
  • No leachables or extractables

 

 

Proven Manufacturing Process

  • Automated, consistent manufacturing process assures reliable performance and repeatable results
  • Thermal and vacuum finishing procedures eliminate potential manufacturing debris

 

 

Wide Range Lengths and Adapters
