Introduction
Parabolic Rundown Screens is a general term we use to cover Parabolic Screens, Rundown Screens and Vibrating, Static Screens.
The non-mechanical, low maintenance aspects of the Parabolic Rundown Screen relies on a uniform feed over a fabricated distribution weir and a reversible wedge wire sieve bend with a cross-flow presentation to allow effective dewatering and gravity solids discharge. Standard radii at varying widths are available to suit flow rate and slot gap requirements.
Wedge Wire profiles and technical data.
Features & Benefits
A mild steel painted or galvanised carcass can be provided for our Parabolic Rundown Screens to accommodate low budgets and client specific applications.
- 304 or 316 Grade Stainless Steel on all wetted parts.
- Efficient separation of liquids & solids.
- Non-mechanical and low maintenance.
- Widths to suit flow rate & slot gap requirements.
- No moving parts.
On-site Demonstrations
Parabolic Rundown Screen on-site demonstration facilities are available along with the entire range of our Waste Water Screening Machines, each with interchangeable screen elements to determine the ideal separation of your materials.
Gap Technology Limited also provide structural steel work including platforms, handrailing and access ladders with a bespoke design, commissioning and installation service.

Vibrating Static Rundown Screens
Easy to operate and used for applications requiring filtration below 0.25mm. With a gravitational inflow, static, vibrating rundown screens are used for separation of solid particles from liquid. Available in a wide range of slot sizes and screen profiles in relation to customer individual requirements. The size of the rundown screen depends on the application and the required capacity. Cleaning will depend on the size of the slot being used. Contact Gap Technology for support and enquiries.
Technical Information & Specifications
Manufacturing variations can include: As-built or retro-fit spray bars with top and front covers incorporating hinged inspection doors (these also cover our Parabolic Screens and Static Screens). Contact Gap Technology for support and enquiries.
