How the FILTOMAT M100 Filters Work
The Amiad Filtomat M100 and MG Series are automatic, self-cleaning filters, ideal for remote installation sites, with
a water-driven self-cleaning mechanism that doesn’t require an external power source for operation. With a variety of
screen areas the M100 and MG models support flow rates of up to 3,520 gpm (800 m3/h), with filtration degrees of 500 down to 80 micron and inlet/outlet diameters from 2” to 14”.
The Filtering Process
The filtration process begins when raw water flows through the filter inlet into the coarse screen which pre-filters the
water to protect the cleaning mechanism from large debris. The water then passes through the inner surface of the
fine screen where dirt particles are trapped and accumulate inside the filter, while clean water flows through the filter
outlet. The gradual buildup of dirt on the inner screen surface causes a filter cake to develop which causes an increase in the pressure differential across the screen.
The Self-Cleaning Process
When the pressure differential across the screen reaches a pre-set level of 0.5 bar (7 psi), the M100 or MG filter starts
the self-cleaning process by opening the internal flush valve. This results in the release of a back-flush stream flowing through the nozzles out of the hollow suction-scanner shaft to the turbine and to the drainage pipe.
