CST Model RD Fine Screens

CST Model RD Rotary Drum Fine Screens deliver high-efficiency screening and solids separation for industrial and municipal wastewater applications. Engineered and manufactured in Australia to AUS-NZ standards, the Model RD is the most widely used and trusted screen in its class, combining full stainless steel construction with complete screenings conveyance, washing, and compaction options to protect downstream processes and reduce operator burden.

Installed in-channel or within a self-supporting tank, the Model RD is fully enclosed for odour and aerosol control and features a corrosion-resistant, self-cleaning design with no mechanical components contacting the screenings. Internal and external spray sparges provide automatic cleaning, while heavy-duty drive systems ensure reliable, long-lasting performance even under high fat, oil, and grease loadings. The Model RD is available with wedgewire or perforated-plate screen options and can be paired with S&L’s complete range of conveyance, washing, and compaction equipment for a fully integrated screening solution.
