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.
