A3 - Channel Screw Screen
The A3 shaftless screw screen offers wastewater screening and transport of solids in a practical and efficient package. Perforated plate or wedgewire screens retain solids, which are lifted and transported by the screw. Brushes continually clean the screening area. Available in a variety of standard and custom sizes.
A3 distributes NRW Contec perforated plate headworks screens. These stainless steel "pump-to" screens are cleaned by means of rotating brushes. Screen perforation sizes range from 0.6 to 20 millimeters. Contact screens require little scheduled maintenance and consistency provide years of trouble-free operation.
Optional equipment includes heat tracing, baggers, and screening compaction and conveyance.
Additionally, A3 offers a full line of inclined channel screens under our own brand. This includes screw screens, bar screens, perforated plate screens, step screens and rotary drum screens.
