HD SERIES INLET PROTECTION BAGS
Standard Sizes: 24” x 24” - 24” x 48”
(circular, high flow ports and custom sizes available)
Our inlet protection bags are designed to protect and filter storm water inlets from harmful
silt and other debris which would otherwise contaminate the storm water system. Our
design allows the silt to settle to the bottom of the bag while allowing water to pass
through. It is the perfect protection for storm water systems. These inlet bags are designed
for maximum flow without sacrificing strength or durability. They are available in a variety
of standard sizes for most applications and can also be ordered in custom configurations to
suit virtually any specification.
