Johnson Screen Solutions High-Performance Filtration For Tough Application

Release Time:

2026-01-31

Johnson Screens, also known as Wedge Wire Screens, are made from low alloy steel and feature support bars with trapezoidal wire sections, which are spot-welded for high compressive strength. These screens offer superior durability, with a single weld joint able to withstand up to 2000N of tensile force. The smooth surface ensures uniform gaps, preventing blockages and providing even filtration. Coated with high-strength, non-toxic industrial plastics, they enhance resistance to acids, alkalis, and reduce electrochemical and biochemical reactions, making them ideal for various filtration applications.

Johnson Screens, also known as Wedge Wire Screen Filters, Wedge Wire Tubes, and Industrial Screens, are highly efficient filtration solutions widely used in water treatment, well construction, and industrial applications. These screens are designed to provide superior filtration performance with precise and customizable slot openings, making them ideal for separating solids from liquids and gases.

Features & Benefits

V-Shaped Slots
The V-shaped slots allow particles smaller than the slot width to pass through, preventing clogging and ensuring efficient filtration.
Large Open Area
The continuous slot design provides more intake area, reducing frictional head loss and improving tube well efficiency.
Better Sand Filtration
With a range of slot sizes, Johnson Screens offer better sand control, reducing pump maintenance and extending tube well life.
Low Maintenance Costs
The screens can be easily cleaned by scraping or backwashing, lowering maintenance efforts and costs.
Maximum Process Output
Precise slot openings ensure accurate separation without media loss, improving filtration and process efficiency.
Energy Saving
Reduced frictional head loss and increased discharge lower pump load, saving 20-25% in energy costs.
Chemical and Thermal Resistance
Made from corrosion-resistant stainless steel and alloys, Johnson Screens withstand harsh chemicals, high temperatures, and pressure.
