Applications of the FlexStorm Pure are car washes, commercial, loading ramps, industrial, gas stations, parking lots, dock drain and maintenance areas.

The specification page gives material and performance, installation, inspection, maintenance and filter bag replacement guidelines.

FlexStorm Pure has a standard woven polypropylene “FX” filter bag rated for 200 gpm/sqft with an 82% removal efficiency when filtering a USDA Sandy Loam sediment load.

The installation guidelines include removing grate from inlet and cleaning the ledge. The inlet filter is then suspended onto the structure’s load-bearing ledge. After replacing the grate, the installer should confirm the grate is no elevated more than 1/8” (3 mm).

Inspection of Pure filters should occur following rain events over ½” (13 mm) and should be monitored to current site runoff conditions. Filter inspections should occur a minimum of three times per year and in snowfall affected regions inspections prior to and after snowfall season. In industrial applications, inspections should be on a recurring basis no less than four times per year.

The Pure inlet filter should be maintained by emptying the filter bag manually or with an industrial vacuum being careful not to damage the geotextile bag. Follow EPA guidelines to dispose of oil-contaminated products and recovered oils.
