Wound Filter Cartridges - Rayon
In Czech Republic

Wound depth rayon cartridges are ideal for filtering organic solvents, and animal, petroleum, and vegetable oils. Wound depth rayon cartridges can be used at temperatures to 1210C and are an economical alternative when food and drug grade rayon cartridges are not required. Fluid compatibility similar to bleached cotton, but with more coarse fibers, and less absorbent than cotton. Swells  in aqueous solutions.

All Rayon wound Cartridges provide true depth filtration through hundreds of tapered filtering passages of controlled size and shape. The diagonal winding of roving on a center core makes a firm interlocking weave that results in a cartridge that prevents channeling and by passing, and greatly reduces fiber migration. As the cartridge is wound, each layer of roving is napped to increase filtration capabilities. As a result, each layer of roving adds its contribution to true depth filtration by trapping its share of particles. In addition, the irregular outer surface helps prevent surface blinding and helps to assure longer cartridge life and full cartridge utilization. Wound cartridges offer a gradual pressure increase during cartridge life versus surface-type media that have an abrupt flow cut off when loaded.
