The Hydro-Flo™ Screen

Patented Stainless Steel Link Grid

The Hydro-Flo Screen is available in both Mesh and Link style grid. The Link style grid is ideally suited for water and wastewater applications where fine screening is required with low headlosses. Stainless steel links, hook links and axles withstand even the harshest of installations. Unlike perforated stainless or molded plastic panels, the laced links are able to filter down to 1 mm openings with extremely high open area percentages. This results in lower velocities through the grid and filtration of higher flows. Easy access to the grid allows for simple cleaning and removal if required. The Link style grid is often selected by designing engineers for screening flows with high solids contents; especially where hard to unload solids such as fats, grease, and stringy screenings are present.

The image on the left is of 1 mm spacing links from the outside of the screen. The image on the right is of a 6 mm spacing screen taken from the inside to show the hooks used for removal of large solids.
