DGD Series cartridges are manufactured from 100% pure polypropylene
and are sized for use in our Big Blue® filter housings.
DGD Series cartridges are designed for purity and will
not impart taste, odor or color to the liquid being filtered.
Additionally, the polypropylene construction provides superior
chemical resistance and is not prone to bacterial attack.
The DGD Series advanced design combines selective “final
filtration” with appropriate “pre-filtration”
to achieve up to three times the dirt-holding capacity of
similar size sediment cartridges and many more times that
of standard spun or string-wound cartridges. This performance
enhancement is achieved by combining two separate gradient
layers in one filter.
The larger diameter of the pre-filter reduces the particle
load to the post filter, allowing it to operate at higher
velocities. The effective filter depth is increased to a
full 233% of standard spun-polypropylene or string-wound
filters. This increased depth provides for very high particulate
reduction efficiencies and added loaded capacity.
The unique design and performance characteristics of the
DGD Series cartridges make them an excellent choice for
all residential, rural, municipal and commercial applications.
