HYDAC filters and filter elements for process technology
For over 30 years we have concentrated on extending service life and on protecting components. Increasing the operational availability of your hydraulic and lubrication systems, as well as reducing downtimes, is still our main focus.
With our innovative products, HYDAC can also set the standards in the Process Technology sector. We supply back-flushing filters and inline filters for many applications in Process Technology.
Special advantage: in addition to high-quality individual components, such as filters, clogging indicators and breather filters, we can also supply sophisticated filtration systems and clever tank solutions.
AutoFilt® TwistFlow Strainer ATF for Process Technology

The HYDAC AutoFilt® TwistFlow Strainer ATF 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 filter is of course particularly suitable for offline applications which can operate for a short time with a slightly reduced flow. 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 to separate the high-density particles (e.g. sand, glass, metal particles, ...) to the edge of the housing.

Automatic Back-flushing Filter AutoFilt RF10

As a manufacturer of automatic back-flushing filter series AutoFilt®, our products have demonstrated their reliable performance in nearly all industrial areas thousands of times. With the new, patented technology of the HYDAC AutoFilt® RF10, we break new ground and offer a solution for applications where conventional back-flushing filters reach their limits. Service spectrum of the AutoFilt® RF10:
- Only depending on the inlet pressure
- Highly-efficient back-flushing even under low-pressure conditions and with long back-flushing lines
- Due to its highly efficient back-flushing, the filter is even suitable for high dirt loads and peaks in contamination
Back-flushing independent of the pressure on the filter clean side.
