Structural characteristics of phenolic resin filter cartridges
Phenolic resin filter cartridges stand out in numerous industries due to their unique structural design and superior performance. Their core is composed of high-strength phenolic resin-impregnated fibers, and this structure provides excellent high-temperature and high-pressure resistance, meeting the filtration requirements in harsh working conditions. The filter cartridges adopt a multi-layer progressive pore design, and the gradually decreasing pore size from the outside to the inside can achieve efficient particle interception while extending the service life of the filter cartridges.
Testimonials
Client’s support is the Best Reward
As a large petrochemical enterprise, we have collaborated with “Zilaiquan” on phenolic resin filter elements for over five years. Their products demonstrate exceptional stability and an impressively long service life even in harsh refining environments, making them a trusted partner.
Jiza Sikuanza
Our fine chemical production line has extremely high requirements for filtration precision. “Zilaiquan’s” phenolic fiber filter cores not only met the standards entirely, but the technical support from their professional team also helped us optimize the entire filtration system, increasing efficiency by approximately 15%.
Peter Monier
“Source factory, customized on demand” is more than just a slogan. We had an old production line that required non-standard filter sizes. “Zilaiquan” responded quickly and delivered a solution that perfectly resolved our spare parts issue and significantly reduced our costs.
