How does the ILS-1 In-line Strainer
Work?
As kitchen effluent flows into the ILS-1
In-line strainer from the top, it passes
over a grate. This grate has openings
that are 1” wide. This strains out any
coarse solids that are greater than 1” in
diameter. These solids slide down the
grate and into a Strainer Basket. This
basket is removable, and should be
emptied a minimum of once per day,
more often if the kitchen is busy. These
strained solids may be emptied into a
trash receptacle.
Meanwhile, the strained effluent exits the unit through a coupling on the
bottom. This flow continues on to a
Big Dipper® Automatic Grease & Oils
Removal Unit. This unit captures and
removes incidental solids less than 1”
in diameter as well as trapping and
removing any free-floating fats, oils and
grease.
