FlexStorm Lite inlet filters are a lower cost alternative for temporary inlet protection. Like all filters, each device is manufactured to fit the specific drainage structure and hangs suspended from the drainage structure with built in overflow bypass. Bags are constructed from our woven monofilament FX geotextile and achieve 84% filtration efficiency in large scale, 3rd party testing. FlexStorm Lite filters are reusable and much easier to install and maintain than fabric-only sacks and bags, which rely on the weight of the grate to hold in place. The FlexStorm Lites provide a reliable and affordable method of inlet protection to comply with ASTM D8057 Standard Specification for Inlet Filters with a Rigid Frame.

FlexStorm Lite™ bags are constructed from our woven monofilament FX geotextile and achieve 82% filtration efficiency in large scale, 3rd party testing. The filter bag and steel framing system has been load tested to over 500 lbs without failure. These filters are reusable and much easier to install and maintain than fabric-only sacks and bags, which rely on the weight of the grate to hold in place.
