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.
