Nominal Retention: 3 µm. Grade No. 131 High retention efficiency for fine crystalline ppt like BaSO4. Slow flow. Higher wet strength and will withstand suction. Nominal Retention: 3 µm. Grade No. 235 Highest retention efficiency collecting very fine ppt. Very slow flow rate. Nominal Retention: 1 µm. Grade No. 101 Creped filter paper captures large particles. Fast flow rate.
