Catch basin insert protects small drains in high-traffic areas while filtering oil, sediment, debris and trash from stormwater runoff.
- Designed for superior filtration and easy handling
- Frameless design is ideal for small drains of any shape that don’t work with our Adjustable Frame Storm Drain Filter or Catch Basin Insert Filtration System
- Heavy-duty, high-visibility strap allows easier handling and removal
- Treats more water and removes more oil than basic storm drain filters; accumulation pocket fits shallow drains to hold sediment, debris and trash
- Four-stage filtration: PET construction removes contaminants from stormwater at multiple stages, increasing the amount of pollutants captured
- Stormwater flows through drain grate onto fabric shelf (Stage 1), passes over filter ring (Stage 2) into collection bag (Stage 3) and over four sets of filter strips (Stage 4)
- Patented filter ring channels water to center of collection bag to prevent untreated water from escaping through overflow ports
- Filter strips float freely like tentacles to remove hydrocarbons as water moves through collection bag
- Overflow ports help prevent blockage during high water flow
- Affordably priced so you can protect more drains at your facility; no need to pick and choose which ones you can afford to safeguard
- Fits circular drain sizes 9″ to 20″ in diameter
- Fits irregular, rectangular and square drain sizes 9″ to 20″ width to 9″ to 20″ length
- Trim to allow 3″ of material to extend above grate
