How the FILTOMAT M300 Filters Work
General
The Amiad FILTOMAT M300 Series are cost effective, easy-to-operate, automatic filters with an hydraulic self-cleaning
mechanism that doesn’t require an external power source to operate.
With their various screen areas, the “M300” models support flow rates of 25-1100 m3 /h (110-4840 US gpm), with
filtration degrees of 3000 down to 15 micron and inlet/outlet diameters from 2”-16”.
The Filtering Process
The filtration process begins when raw water flows through the Filter Inlet (1) into the Coarse Screen (2).
Here, the water is pre-filtered in order to protect the cleaning mechanism from large debris.
The water then passes through the inner surface of the Fine Screen (3), dirt particles are trapped and accumulate
inside the filter while clean water flows out of the Filter Outlet (4).
The gradual dirt buildup on the inner screen surface causes a filter cake to develop with a corresponding increase in
the differential pressure across the screen’s inner and outer surfaces.
The Self-Cleaning Process
When the differential pressure across the screen reaches a preset value, the filter’s Rinse Controller (5) starts
the cleaning cycle. In the piston-less models the Hydraulic Valves (6) are activated where in the piston models the
Piston (7) together with the hydraulic valves are activated. This creates a pressure drop in the Motor Chamber (8)
and a backflush stream that flows out of the filter to the drain through the Nozzles (9), the Dirt Collector (10) and the
Hydraulic Motor (11). The vacuum action and spiral motion of the Dirt Collector cleans 100% of the fine screen.
The byPass Option (M400 models)
In applications that require continuous supply of water, such as in fire protection systems, Amiad provides the optional
M400 bypass feature. The bypass is triggered in cases of system fault that cause the filter’s screen to become blocked.
Unfiltered water follows through the bypass until the screen is cleaned. Once the screen is cleaned, the filter resumes
normal operation.
”M300 Series” Models
