The Johnson Screen, also known as a filter pipe, is a durable filtration solution developed by the American company Johnson. Made from high-quality stainless or high-manganese steel, its V-shaped wires are welded around support rods, providing strength and preventing clogging for smooth water flow. Ideal for deep well and submersible pumps, this screen is widely used in petrochemicals, wastewater treatment, mineral processing, and food production. Its corrosion resistance, smooth surface, and easy maintenance, combined with factory-direct pricing, make it a reliable and economical choice for industrial filtration applications.
The Johnson Screen, also known as a filter pipe, was first introduced by the American company Johnson and hence named after it. This screen is made by pre-rolling stainless steel or high-manganese steel into V-shaped wires (screen wires or bars), which are then wrapped around support rods and welded together. Each intersection is fused, resulting in a robust structure with excellent mechanical properties. The V-shaped profile prevents clogging while ensuring smooth water flow. It can be used alongside deep well pumps and submersible pumps, as well as in water treatment equipment and environmental protection applications.
