Description

ERTEC Combo Guard is a temporary sediment filter designed for curb and grate inlet protection during construction. It is constructed from a durable high-density polyethylene (HDPE) outer jacket with an integrated 425-micron geo-textile filter. The system intercepts sediment-laden water, allowing flow while filtering smaller particles and providing high-flow bypass openings to prevent flooding. This reusable device is lightweight and easily installed using gravel bags, cable ties, or concrete anchors.

Features

  • Integrated 425-micron particle filter allows a flow rate of 145 gpm/ft2.
  • Durable HDPE construction makes the unit reusable and long-lasting.
  • Built-in high-flow bypass set at 2 inches high to handle heavy rainfall.
  • Gasket seal controls underflow to ensure water passes through the filter.
  • Extremely lightweight at 3 to 5 lbs for easy handling and maintenance.
