GRTB-Series High Rigidity Grade Polypropylene Meltbown Cartridges
Our new GRTB-Series High Rigidity Grade Polypropylene Meltblown Filter Cartridges are engineered for demanding applications where strength, consistency, and contaminant retention are critical. Built with a highly rigid, all-polypropylene construction, these cartridges are designed to maintain structural integrity in elevated viscosity and high differential pressure environments—delivering reliable performance where traditional depth filters can fall short. With precision-controlled fiber layering, the GRTB optimizes dirt-holding capacity and filtration efficiency, helping extend service life and reduce change outs across a wide range of industrial and process applications.
We will begin fulfilling orders as early as June 30, with samples and trial orders available upon request to support your evaluation and qualification process.
- Highly rigid construction offers collapse resistance in elevated viscosity applications.
- Precision process control of fiber diameters allow for layered density; optimizing loading capacity and overall performance.
- All polypropylene construction delivers excellent
compatibility with a wide range of chemicals. - Resists contaminant unloading, even at elevated
differential pressures.
- All thermally-bonded end configurations
available. - Easy cartridge incineration and disposal.
- Free of additives, wetting agents, binders and
silicone. - Potential alternative to resin-bonded (GRU-V)
