Product Description
The Johnson Type Continuous Slot Wire Screen Hi-Flow Stainless Steel Screen, also known as Johnson screen or water well screen, is a premium filtration solution widely used in oil, gas, and water well sand control applications. Manufactured using a full welding production process with special trapezoidal wire winding on circumferential support rods, this screen offers exceptional durability and performance.
Featuring a unique keystone slot design that widens toward the inner side of the screen, this product delivers superior anti-plugging performance and self-cleaning action. The precise slot width is designed to be approximately twice the size of formation sand for optimal filtration.

Key Features
- High Open Area: Optimized for high-quality water wells, oil wells, and gas wells with superior flow characteristics.
- Energy Efficient: High open area promotes groundwater infiltration, reducing water level drop and saving energy consumption.
- Pump Protection: Slower water entry velocity prevents sand intrusion under pressure, reducing pump abrasion.
- Extended Well Life: Gradual water flow through the screen structure significantly extends well lifespan.
