Description

GVB Mechanical Screens consist of a robust steel frame and a bar filter, varying according to the screening efficiency required.
GVB screens are used for coarse screening in both municipal and industrial waste water plants.

Function

Waste water flows into the upstream end of the unit where screenings is captured on the bars.
Chain-driven rakes clean the bars, conveying at the same time the solids to the discharge point.
There material is removed from the rakes by a wiper and discharged into a dumpster, conveyor or compactor.

Features

• > 12mm ~ 50mm spacing
• 2 or more cleaning rakes ensuring quick, efficient solids removal
• Channel width: 400 ~ 2,000 mm
• 75-degree incline angle

Benefits

• Precision laser-cut raking tines cut from single stainless steel bar
• Recessed guide channels for drive chains reducing chain exposure to screenings
• Lower chain guide with no moving parts
• No lower sprocket nor bearings
• Reduced service requirements (no need to take screen out of channel)

Options

• Alternative screen types and sizes
• Material: hot dip galvanised steel, 304 L / 316 L SS
• Incline angle other than 75 degrees up to 90 degrees with goose neck
• Alternative voltage and frequency
• Alternative degree of motor protection
• Control panel
