CST Model SF Spiral Fine Screens
CST Model SF Spiral Fine Screens
CST Model SF Fine Screens provide simple, reliable, and cost-effective fine screening for municipal and industrial wastewater applications. Engineered and manufactured in Australia to AUS-NZ standards, the system combines robust stainless steel construction with efficient screenings removal, washing, and compaction to protect downstream processes and reduce operating costs.
Designed for concrete channels or piped systems with optional stainless steel tank enclosures, the Model SF effectively removes non-biodegradable solids and debris. Its shaftless screw design, lack of intermediate bearings, and low-speed intermittent operation minimise maintenance requirements while ensuring reliable performance, even with long, fibrous materials. The Model SF can be integrated into packaged inlet works and paired with the Smith & Loveless PISTA® Grit Removal System for a complete preliminary treatment solution.| CST Model SF Fine Screens Technical Data | |

Advantages
Robust Construction
Fabricated from 304 or 316 stainless steel for long-term durability in demanding municipal and industrial wastewater environments.
Odour Control
Can be fully enclosed to minimise odour emissions and improve performance in sensitive installations.
Solids Reduction
Extracted screenings volume reduction of up to 40%, reducing handling and disposal requirements downstream.
Screenings Washing & Compaction
Integrated washing and compaction system improves dewatering efficiency and prepares screenings for landfill disposal or reuse.
No Contact With Screenings
Shaftless screw design eliminates bearings in contact with solids, reducing wear and improving maintenance access.
No Jamming / Blocking
Engineered wedgewire/perforated screen design prevents clogging, even with long fibrous material in wastewater flow.
Frequently Asked Questions
The Model SF Fine Screen is engineered for demanding wastewater environments, using robust 304 or 316 stainless steel construction and a shaftless screw design to ensure reliable operation in both municipal and industrial headworks applications.
The system eliminates hanger, intermediate, and bottom bearings and uses a shaftless screw conveyor, reducing wear points and simplifying long-term maintenance while supporting continuous or intermittent operation.
Yes. The system can be fully enclosed with the SFT tank option, helping to contain odours and improve environmental performance in sensitive installations.
The Model SF can reduce extracted screenings volume by up to 40%, with integrated washing and compaction options to further decrease handling and disposal requirements.
