Description

GVF Mechanical Sub-vertical Fine Screens consist of a robust steel frame and a bar filter varying according to the screening efficiency required.
GVF screens are used for medium-fine screening of both civil and industrial sewage.

Function

Waste water flows into the upstream end of the unit where screenings are captured on the bars.
While the chain-driven rakes clean the bars, material is conveyed to the discharge point.
Solids are removed from the rakes by a wiper and discharged into a dumpster, conveyor or compactor.

Features

• 6 ~ 10mm spacing
• 4 or more cleaning rakes depending on screen height
• Channel width: 400 ~ 2,000 mm
• 75-degree incline angle

Benefits

• Rake tines precision laser-cut from continuous stainless steel bar
• Upper and lower sprocket to maintain strict alignment required by fine bar spacing
• Self-lubricating lower bronze bush enclosed in sealed casing
• Reduced service requirements (no need to take screen out of the 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
