AFI-FS – Water Filtration System

MULTI GRADE FILTERS

The “AFI-FS” “ESP” and “GHL” series of multigrade filters have been designed for effective reduction of particulate and colloidial matter in the water supply. Aqua Filsep multigrade filter operates on the principle of depth filter. Filters are charged with coarse and fine quartz silica sand mixed together in a required proportion. The benefits of graded mixed media is, that it produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles. These filters are operated at substantially higher specific flow rate than conventional filters.

Our standard “ESP” and “GLH” series of filtration System range from 0.75 M3/hr to 210 M3/hr. GHL Series are made from FRP and ESP series from Mild Steel.
