Wound Filter Cartridges - Polypropylene
Wound Depth Polypropylene Cartridges
have broad chemical compatibility with many different fluids
and also have excellent resistance to micro-organisms. They
have a maximum operating temperature of 700C and
are constructed of materials, which meet Food and Drug
Administration requirements. The finish of synthetic
polypropylene does not impart tastes or odor and is
low-foaming.
All Polypropylene 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
