Overview
Continuous Slot Wedge Wire Screens
Continuous slot wedge wire screens, also known as Johnson screens, are engineered for high-efficiency filtration and separation applications. By utilizing a V-shaped profile wire wrapped around longitudinal support rods and fusion-welded at every intersection, these screens create a continuous slot opening that allows for maximum flow while effectively retaining sand and gravel. Their robust construction ensures excellent corrosion resistance and durability in demanding water, oil, and gas well environments.
