grids from Filbur are designed for Diatomaceous Earth
filter applications. All grids are constructed with a
reinforced center core for added durability. Seams are
stitched with heavy duty, chemical resistant string and
are sonic welded to prevent fraying. Make the switch and
notice the difference.
grids use a 100% Polypropylene cloth. Polypropylene is
mildew and rot resistant and has excellent resistance to
acids and alkalis. This material has been in use in the
Pool and Spa industry for over 50 years. During this
time the Polypropylene material has gone through several
modifications. Improvements such as yarn construction,
weave pattern, and fabric finishing allow for better
control of the fabric's "permeability" in order to
optimize the D.E cake characteristics.
