The Lech series sediment pre-filter can be installed as part of whole house water treatment as the first line of clean and healthy drinking water and usually installed in equipment room/behind the water meter/main water line. This sediment pre-filter is constructed of stainless steel 40 micrometer filter so it does not require filters to be replaced. By using a large flow design, it is capable of achieving 50 liters of filtration per minute or 3 m3/h. In addition, 360° rotary scraping can easily solve the clearance issue regardless of the location of the installation.
