Products Description
Grooved resin bonded cartridges are single-piece, coreless filter elements manufactured by impregnating a fibrous media with phenolic resin and machining a grooved surface profile. The grooves increase effective surface area and promote even flow distribution, letting each cartridge combine high dirt-holding capacity with stable retention across a broad range of process chemistries, viscosities and temperatures.

Applications
- Chemical processing: solvent filtration, acid purification
- Coatings industry: paint, ink, and varnish clarification
- Industrial fluids: lubricants, hydraulic oils, coolants
- Process water: pretreatment and final polishing
- Adhesives & resins: particulate removal and gel reduction
quality control
Our grooved resin bonded cartridges are manufactured under controlled processes to ensure consistent porosity, retention and structural strength. Typical QA measures include:
- dimensional verification,
- differential pressure testing,
- batch porosity and retention sampling
- compatibility checks for gasket materials.
If required, we can support: material declarations, certificate of conformity, and sample testing programs for customer trials.

FAQ
Q: Are these filters suitable for high-viscosity fluids (e.g., heavy oils)?
A: Yes. The rigid phenolic matrix sustains pore geometry in viscous media; provide viscosity and operating ΔP so we can recommend the best variant.
Q: Which is better for inks: grooved or ungrooved?
A: Grooved cartridges are preferred when solids are abundant because they increase surface capture and extend run life. Ungrooved cartridges are better for gels or deformable contaminants to avoid entrapment/release behavior.
Q: Can I clean and reuse the grooved resin bonded cartridge?
A: No. Depth resin-bonded cartridges are generally single-use. Cleaning rarely recovers original efficiency.
