Johnson wire wrapped screen is used in the field of sugar juice filtration, waste water treatment, crude oil and natural gas production and vessel internals solving problems of solid/liquid and solid/gas separation; filtration of oils, greases, paints, food products, fuels, liquid cooling agents, chemicals etc.
Johnson wire wrapped screens are rod based continuous slot screens, opening significantly increases the available open area, providing greater access to the water-bearing zone.
Non-clogging: "V" shaped or wedge shaped profile wire, avoids clogging, is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and don't wedge in the screen's inwardly enlarging slot.
Large open area: this allows more water to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.
