High Viscosity Fluid Filter Papers
- Thick, high and low-density filter papers designed for fast filtration of viscous fluids
Grades
No. 63 • 1 mm thick filter paper; standard type for a variety of filtration applications
No. 63F • 1.35 mm thick, high density filter for increased particle reten- tion than No. 63
No. 63G • For filtration of high viscosity liquids with fine particle sus pensions; can be used in high pressure systems
No. 60, 65, 462 • Thinner, lower density filter papers for gentle filtra- tion of high viscosity fluids
