Did you know
- HYDAC has been producing filters since 1963, and the AutoFilt series, which includes Duplex Filters, has been continuously expanded over the years to offer various back-flushing filter concepts.
- The Duplex Filter Series (AutoFilter) is part of HYDAC's broader AutoFilt series of automatic back-flushing filters, which are designed for process and engineering technology applications. Within this series, models like the RF3, RF4, RF7, RF9, RF14, and RF15 offer different specializations, such as handling various fluid viscosities, installation heights, or specific contamination types.
- The Duplex Filter Series is chosen for its ability to provide continuous filtration without interruption, even during back-flushing, ensuring operational reliability and reducing maintenance costs. Its robust construction and automatic self-cleaning capabilities contribute to increased service life for system components.
