Fully automatic continuous filtration, extending the lifespan of filter media, excellent maintainability, and achieving high quality in the filtration process.

**Automatic Backwashing Filter Equipment with Patent Technology by Lenzing AG, Austria** ~ Selling worldwide as an expert in solid-liquid separation technology since the 1970s ~ High-efficiency filtration is possible with a fully automatic continuous filtration/backwashing system. It features a space-saving and simple mechanism, ensuring excellent maintenance. The backwashing system is expected to significantly reduce running costs by decreasing the frequency of filter media replacement. The sealed mechanism protects operators from solvents and harmful substances, contributing to an improved working environment. It can filter a variety of slurries and dope fluids, from low to high viscosity. The backwashing system allows for the removal of not only solids but also gel-like foreign substances. Rental test units are also available. We have a proven track record in various fields. If you are considering improving filtration quality, enhancing the working environment, or replacing existing filter equipment, please contact us first.
