GRB Series Grooved Resin Bonded Filter Cartridges


GRB Series Grooved Resin Bonded Filter Cartridges are mainly made of acrylic fibers and resins, with the addition of adhesives, curing agents and stabilizers through high-temperature sintering. Resin bonded filters have a gradually tightening hard structure that allows the cartridges to withstand extreme viscosity and temperature without deformation or collapse. The quality of Hongtek resin bonded cartridges are equivalent to 3M's Micro-Klean filter cartridges,are loose on the outside and tight on the inside, with uniform micropores and high porosity, allowing larger particles to be intercepted on the surface of the filters, while smaller particles are intercepted on the inner layer, belonging to deep filtration, thereby increasing the interception capacity and service life. It adopts a processing process to add grooves on the surface of the resin bonded filter cartridges, thereby expanding the effective filtration area and achieving an ultra-high filtration efficiency of 99.9%. Resin bonded cartridges are widely used in many chemical industries.
