The FSM - Multi Rake Bar Screen was developed to deal with particular problems associated with sewage pre-treatment plant.

Parallel to the increasing demands of users, FSM introduced modifications to the basic design.
These have resulted in an optimum product for the preliminary treatment of waste water-providing high performance coupled with low operating costs. The Multi rake bar screen is a coarse and fine screen and use in water and waste water treatment predominantly thought.

Functional principle:
The waste water flows through bars made of stainless steel, while contaminants are held back. Solid matter is picked up directly at the bottom of the channel without the need for a bottom recess. The cleaning elements are fixed between two chains and are designed with teeth for the best cleaning of the screen. The screenings can be discharged into containers, wash compactors, screw conveyors, conveyor belts etc.

Features:
• High reliability through robust construction – no need for upstream coarse screening.
• The Multi Rake Bar Screen allows the passage of grit without malfunctioning.
• Discharge of coarse matter through large rakes
• Screen field optimally cleaned as a result of the teeth of the rakes.
• Screenings conveyed positively to the discharge point.
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Easily adapted to suit changed operating conditions
• Machine completely hygienically encapsulated
