Flights

Overview

Brentwood offers more flight scraper options than any other chain and flight manufacturer, enabling us to provide sludge collection solutions for any water or wastewater application. In addition to industry standard c-channels, Polychem’s flight offering includes the proprietary Ultra, Ultra Plus, Box, and Bridge flights for heavy loadings and deep sludge blankets. The Ultra Plus and Box flights provide sturdy and reliable options for wide tank applications, and the Bridge flight is the ultimate solution for wide tanks that require tall scrapers.

All Polychem flights feature a flat-face design to eliminate the potential for recirculation of solids and are fabricated from UV-inhibited isophthalic polyester resin. They offer a flexible solution that accommodates tank wall variations and can be supplied pre-drilled or -notched to account for floor and return rail locations.

Features

  • Integral scraping lip provides superior tank scraping
  • Fiberglass roving & mat run full length of flight
  • Optimized resin-to-glass ratio maximizes stiffness & durability
