Polychem® Flights
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 offerings include the proprietary Ultra, Ultra Plus, Box, and E-Flight profiles for heavy loadings and deep sludge blankets. The Ultra Plus and Box flights provide sturdy and reliable options for wide tank applications, and the E-Flight is the ultimate solution for processes that require a taller scraper flight.
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.

Attachment Links
Brentwood’s attachment links are designed to be used with our NCS-720-S collector chain and are precision molded from the same glass-reinforced polyester material. These links extend the full depth of the flight and are integrally molded in one piece to ensure proper flight alignment.
Filler Blocks
Used in conjunction with fiberglass flights and chain attachments links, Brentwood’s polypropylene filler blocks act as rigid spacers between the back of the flight and the attachment paddle. Filler blocks are specifically designed to fit each flight to ensure proper connection and to allow for full use of each profile.
Wear Shoes
Wear shoes are molded from durable Nylon 6-6 material and can be supplied with slotted holes to accommodate any hole pattern. They are radiused to smoothly transition over the wear strip joints and are reversible, providing two useable wearing surfaces. For wider tank spans, wear shoes can be used to support the middle of a flight.
Squeegees & Wipers
Made of synthetic rubber, squeegees and wipers can be furnished on flights to thoroughly clean the tank side walls and skim the full basin width on the flight return run. These accessories have slotted holes for adjustability and are mounted to the scraper flights using 316 SS hardware and FRP backing plates. Squeegees are also used on skimmer assemblies to transfer scum into troughs.
Hardware
The Polychem hardware kit is standardly provided in corrosion-resistant 316 SS. They come prepackaged for ease of inventory and installation and are also available in alternate materials, such as Monel for applications with high chlorine content.
