Problems It Solves

Problems This Range Removes

  • A plant runs out of stock on a critical OEM cartridge and faces a long lead time while the line stays idle
  • A cartridge leaks at the seam or joint during operation, contaminating the process stream
  • The filter media collapses under differential pressure, reducing flow and allowing bypass
  • The micron rating is not consistent across the filter pack, leading to breakthrough of fine particles
  • The cartridge does not fit the existing housing due to mismatched diameter, length or adapter style
Why This Range

What You Get With This Range

Single Piece Full Length Construction

No joints in the filter hardware reduce leak risk and ensure consistent filtration across the full length.

Consistent Micron Rating Across the Pack

The pleated design with full length support maintains the rated micron throughout the element.

Built to Fit Installed OEM Housings

Dimensions and adapter styles match common OEM series so no piping or vessel changes are needed.

Configured to Your Housing

Micron rating, O-ring compound, and adapter are set based on your housing model before shipping.

Application Scenarios

Where These Are Installed

RO Pretreatment

Removal of suspended solids and colloids before reverse osmosis membranes to prevent fouling and extend membrane life.

Chemical Processing

Filtration of aggressive liquids at high temperature and pressure where material compatibility is critical.
