Liquid Filter Series

WANSON FILTER manufactures all-welded Johnson Screen Filter (also known as Vee-Wire® screens or wedge wire screens) for superior liquid/solid separation. Our unique design features a continuous V-shaped wire wrapped around internal support rods, creating a self-cleaning, non-clogging slot.

Non-Clogging Design: The V-shaped wire creates a continuous slot that is wider at the inside than the outside, preventing particles from lodging and maximizing flow rates.
High Mechanical Strength: Every intersection of wire and rod is automatically welded, resulting in a robust, cage-like structure that withstands high differential pressures and heavy loads.
Maximum Open Area: The design allows for up to 60% open area, significantly increasing flow efficiency and reducing energy consumption compared to bridge-slot or slotted pipe screens.
Superior Corrosion Resistance: Fabricated from high-quality Stainless Steel 304, 316L, and other alloys to endure harsh chemical, high-temperature, and corrosive environments.

Our Johnson screens are vital for water wells, oil and gas processing, mining and mineral separation, and pulp & paper industries. WANSON FILTER provides comprehensive customization for flat panels, cylindrical screens, nozzle cups, and lateral systems to meet your exact specifications and flow requirements.
