Raptor® Micro Strainer

Ideal for small treatment facilities, the Raptor® Micro Strainer is a screen with a semi-circular basket with small apertures ranging from 0.04 to 0.25-inches (1 to 6 mm). It captures small debris that passes through other screens. A perforated plate or wedge wire basket is available for municipal or industrial applications. The captured screenings are washed, compacted, and dewatered to a dry solids content of 40 percent as they are transported up the inclined screw for disposal. This step reduces the volume by 50 percent and weight by 67 percent, ultimately reducing disposal costs.


  • All stainless steel construction resists corrosion
  • Screens, washes, compacts and dewaters solids in one unit, reducing disposal cost
  • Lower polymer bearing blocks promote longer brush life and can be replaced without disassembling the screen
  • Thicker screenings basket and transport tube for longer life
  • Dual spray wash system returns organic material to the wastewater flow
  • Vertical orientation – suitable for manholes and pump stations
  • Simple design with a single drive minimizes maintenance cost
  • Tank mounted screens are available
