Also, 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." The larger diameter of the pre-filter, prefilter, pre filter reduces the particle load to the post filter, allowing it to operate at higher velocities. This increased depth provides for very high particulate reduction efficiencies and loading capacities. Order a case of 8 and save even more.
