HYDAC AutoFilt® TwistFlow Strainer ATF

The HYDAC AutoFilt® TwistFlow Strainer ATF is suitable for the separation of solids from water and fluids similar to water. With filtration rating between 200 and 3000 μm, the AutoFilt® TwistFlow Strainer ATF is particularly suitable for the separation of suspended solids up to several grams per litre from preferably low-viscosity media.

The AutoFilt® ATF is suitable for the solid/liquid separation of low-viscosity media, and is used for example for:

  • Preliminary separation ahead of AutoFilt®RF3 / RF4
  • Pre-filtration for relieving sand filters
  • Pre-filtration before membrane systems
  • Filtration of surface water
  • Filtration of sea water
  • Filtration of process water
  • Filtration of waste water

This filter apparatus is a hybrid system comprised of a centrifugal force separator and an inline filter. The fluid to be cleaned — in a fashion similar to that of a centrifugal force separator — is streamed in tangentially to the housing and accelerated downward through the reduced housing cross-section. This results in the formation of a spiral-shaped streaming which, due to the centrifugal forces generated, first conveys the coarsest of the contaminations — the densities of which are considerably greater than those of the fluid — to the inner wall of the container.
When pressed against the filter wall, the particles sediment at a higher density in the lower part of the filter, where they are finally carried out. The remaining particles, which only marginally differ in density from the fluid, are separated by a conical filter element which is located in the middle of the filter.
