The vertical bar screen meets the need to have a separation of the coarse screenings from wastewater, whether civil or industrial. The standard application involves the installation inside of channels constructed in reinforced concrete, to which the machine is laterally fixed.

The machine is composed by a bearing structure made of stainless steel. The machine has a filtering surface, with a spacing which can vary from 15 to 40 mm, with which are retained the screenings which have a size greater than the spacing aperture chosen, while the filtered water is allowed to pass. The screenings are lifted, transported and discharged using combs, that are also suitable for cleaning the filtration area.

The combs are made of polyethylene mounted on special steel supports and directly fixed to a chain made of stainless steel. In the discharge area is located a scraper which has the function to discharge the screenings and consequently clean the combs. The machine runs driven by a gearmotor.

The part of the machine which comes out from the channel is protected by a stainless steel frame. The machine can be made of stainless steel AISI 304, AISI 316 or hot dip galvanized steel.
