Filter with manual control of FDR series

Two-cameras manual filters work on the principle of trapping mesh filter elements each of the cameras of pollution and their accumulation in the cameras with subsequent manual cleaning.

Technical features

  • Line Filter fits on the case in the water pipe;
  • Filter has two independent cameras for collecting of solid particles;
  • Continued filtration of the water purification filter of one of the cameras;
  • Low pressure difference across the filter;
  • Filter reliably works in all system pressures (up to 20 bar);
  • Filter works reliably in the presence of water large inclusions;
  • The complete absence of water loss by washing filter elements.

Designs description

FDR filter consists of a cylindrical body and two cylindrical filter blocks. Filter blocks are at the bottom of the hatches on the hinges, pressed against the flange bolts. In the filter blocks are installed cylindrical mesh filter elements. The filter blocks are connected to the filter body with flanges, between which normally open butterfly valve with manual control.

When filtration water enters the filter body and its flow is branched at the top of the housing into two flows into the left and right filter blocks. In each filter block water passes through the filter element and through the bottom nozzles are cleaned enters the lower part of the body and further into water pipeline.

For cleaning, for example, overlap the left camera at the left hand valve filter block of the water is drained through the valve unit into a separate container, open cross hatch unit discharged from a solids, is removed and cleaned grid. After that put the grid in place, close the door, close the valve to drain the water, open the flap near the left block.

Similarly, the right to purification filter block.

The filter design allows you to use it without a bypass line.
