PRB Series Phenolic Resin Bonded Filter Cartridges
Phenolic resin bonded filter cartridge
PRB Series phenolic resin filter cartridges excel in filtration efficiency due to a unique manufacturing process, establishing a rigid structure with graded porosity. This design captures coarser particles near the surface and finer particles toward the core. The graded porosity structure reduces bypass and eliminates the unloading characteristics seen in soft and easily deformable competitive melt-blown and string-wound filter cartridges.
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.
Please refer to the application guide for additional information.
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.
