Filter Sheets
Gusmer Enterprises’ Color Sensitive Filter (CSF) series is manufactured using advance technologies that allow less initial color stripping during filtration, yet offers the same outstanding performance of conventional filter sheet media. Gusmer’s CSF gradient density filter sheets are a composite of the finest cellulose pulps and filter aids. Produced with a controlled porosity, the CSF sheets have superior throughput capacity and excellent retention capabilities. Available in 5 grades, the CSF series can be relied on to remove micron and sub-micron particulate, such as gross solids, haze constituents, yeast, bacteria and colloids on a consistent basis, yet preserves color, aromas and flavors in beverages and other various liquids. For more detailed information on grade selection, please contact your Gusmer representative.

Additional Filter Sheet Series:
- 1300SD Filter Sheet Series
Gusmer’s 1300SD series of pure cellulose depth filters offers enhanced contaminant loading capacity. This media series contains a blend of cellulose fibers suitable for filtration applications in the 1-20 micrometer range. The 1300SD series exhibits high wet strength, low extractables, and increased throughput and is recommended for applications where diatomaceous earth containing media is unsuitable. - 1700W Filter Sheet Series
Gusmer’s 1700W depth filter sheets are specifically designed for coarse, polish, premembrane and bioreduction filtration applications in the food and beverage industry. The 1700W series consists of 11 different retention grades. Each grade consists of mixtures of cellulose and kieselguhr, exhibiting a positive zeta potential for a full range of reliable filtration performance for all applications. - 1900SD Filter Sheet Series
Gusmer’s 1900SD series of gradient density depth filters provide superior throughput capacity, thus reducing filtration costs. This range of controlled prorsity media exhibits positive charge properties to enhance filtration performance and provides higher wet strength, low extractables, and increased throughput due to advanced manufacturing technologies.
