Filtration of Solid Particles

The AutoFilt® Twist Flow Strainer ATF from HYDAC (Germany) is suitable for the intermittent filtration of solid particles from water or fluids similar to water. Since only a portion of the flow is used to clean the filter, filtration can continue virtually unaffected.

The fluid enters the housing tangentially. As a result of the tangential flow and the tapered housing cross-section, the fluid flows down spirally.

The centrifugal forces created separate the high density particles (e.g. sand, glass, metal particles,...) to the edge of the housing.

These are then deposited in the lower part of the housing and can be cleaned out periodically.

The remaining low-density particles which are not deposited at the bottom of the housing by the centrifugal force are separated by the conical slotted tube which has a defined filtration rating.
