Cylindrical Wedge Wire Screen
The most widely used wedge wire screen type, also referred to as Johnson-type or continuous slot screens in the industry. The continuous V-wire slot design provides maximum open area and non-clogging performance along the full length. Available in static or rotating configurations for water treatment, mining, food processing, and petrochemical filtration.
APPLICATIONS
• Water treatment & intake
• Mining & mineral processing
• Food & beverage filtration
• Petrochemical screening
