Automatic Inline Strainer

Automatic self cleaning inline strainer

The automatic Inline strainer is a self-cleaning unit designed for removal of heavy dirt loads and big particles from intake, process and wastewater flows. Depending on the screen the automatic strainer can handle solids with particles as small as 200 micron and large as 5000 micron. Raw water enters the inside of the screen cylinder and flows through the screen to the outlet. A filter cake of dirt is build on the inner screen, cleaning process starts when the differential pressure reached a preset value. Cleaning is done by a brush system, stainless steel/nylon brushes sweep the inner surface of the cylindrical screen. The particles are dislodged and flushed out to the exhaust valve. The In-Line strainer serie range in flow rates up to 4.500 m3/hr, with screens ranging from 5.000- 200 micron filtration degree. Outlet flanges goes up to 32” diameter.
