The specialists for environmental technology

The FSM Trash Rack Screen has been developed in reference to the increasing demands of users. These resulted in an optimum product for- coarse cleaning of waste water - providing high performance coupled with low operating costs.
The FSM Trash Rack Screen thus offers ideal protection for pumping and fine screening installations. The Trash rake screen is a coarse screen for channels of large depth and width use in water and waste water treatment predominantly thought.

Functional principle:
The waste water flows through a bar screen made of steel or stainless steel, while screenings are held back. Solid matter is picked up by our special grab directly at the bottom of the channel without the need for a base step. The teeth of the grab act between the bars of the screen thus preventing jamming of the screenings. The grab moved up and down by a rope. Opening and closing of the grab is achieved by a hydraulic cylinder.

Discharge of the screening is into a container, wash compactor, screw conveyor, conveyor belt etc.

The position of the grab is controlled by a rotary selector switch. Thereby different positions on the screen field can be reached by the grab. For digger operation the rope is controlled by a slack rope weight.

Features:
• High reliability through robust construction
• The FSM Trash Rack screen allows the passage of grit without malfunctioning
• Screenings are fixed between Front and back rake, no falling back in the channel
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Easily adapted to suit changed operating conditions
• The FSM Trash Rack Screen unit has proved itself in practice at home and abroad
