Water Filters

The WISY filtering principle uses a vertical filter mesh. Solids such as leaves, moss or particals from production processes are simply flushed past the filter and get separated with a very high efficiency.

    • Downpipe Filter for Rainwater
    • Made of stainless steel
    • Roof areas up to 150 m² or 1,615 sq.ft.
      (temperate climate zone)
    • Vertical 0.28 mm filter element integrated
    • Effective separation of dirt particles
    • 10-year guarantee
    • Easy access to filter insert
    • Extremely low maintenance
