Externally Installable Curb Inlet Catch Basin Filtration Apparatus

摘要

A filtration apparatus for curb vaults may be installed in existing vaults through the road-level inlet opening into the vault. A support plate assembly of the filtration apparatus suspends a primary and secondary filter and is movable between extended and retracted positions. An adjustable attachment system allows installation of the filtration apparatus by inserting the apparatus through the inlet opening.
