PRB Series Phenolic resin filter cartridge
PRB series cartridges, constructed with polyester fibers and phenolic resin, excels in durability and resilience, withstanding extremes without compression. The grooved surface structure extends the overall filter life while increasing dirt holding capacity. These filters deliver a unique, durable, and high-performance solution for demanding applications, ensuring exceptional chemical and heat resistivity. This makes the PRB series ideal for a range of challenging conditions, including high-temperature, high-viscosity, and high-pressure applications like paints and coatings.

Phenolic Resin Bonded Filter Cartridge Feature and Benefit
Broad chemical compatibility
Rigid construction makes it ideal for high viscosity chemical liquid filtration and chemically aggressive applications, offering solvent resistance, corrosion resistance, and broad chemical compatibility.
Ideal for high flow and high temperature applications
No deformation in high-flow, high-temperature conditions, excelling with solvent-based liquids and high-viscosity fluids, regardless of temperature, pressure, or viscosity levels.
Graded porosity structure
Ensuring consistent filtration performance, these filters offer low pressure drop, long life, higher contaminant-holding capacity, excellent particle removal efficiency, and high dirt-holding capacity
Rigid resin bonding structure
The rigid resin bonding structure is designed to prevent the unloading of materials in situations with high pressure, ensuring stability even when there are notable pressure fluctuations
Broad filtration range
Available in a wide range of removal efficiencies from 1 to 150 microns for diverse applications.
Grooved surface structure
The grooved surface structure in resin-bonded cartridges increases filtration area, enhancing dirt loading capacity and prolonging on-stream life.
