pure round wedge wire filter element

Stainless Steel 304 Johnson Screen, 3000mm length

Also be named continuous slot water well screen, wound screen, wire wrapped screen.

The Water wire continuous slot screens are made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods.

Continuous slot: support rods and longitudinal wire makes an opening which significantly increase the available opening area, and allow better access to the water flow.

High open area: reduce the water level, thus to save energy consumption. Meanwhile, high open area can make the groundwater enter the screen much slower than other filtration apparatus, which can avoid sand from entering screen due to high pressure, hereby lowering pump wear down.

High Strength: It takes stainless steel as main raw material, then is welded at high temperature, which guarantee high strength to bear big water pressure, hereby it has long life span.

Specificarion:

1. Production process continuity:

   V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.

2. Low maintenance costs:

    Separation at the screen surface which can easily cleaned by scraping or back washing.

3. Maximum process output:

    Precise and continuous slot openings resulting in accurate separation without loss off media.

4. Low operational costs:

   Large open area with an effective flow, high yield and a low pressure drop (dP)

5. Long live:

    Welded at each intersection creating a strong and durable screen.

6. Reduced installation costs:

   supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.

7. Chemical and thermal resistant:

  A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.

Each slot opening between adjacent wires is V-shaped, resulting from the special shape of the wire used to form the screen surface.

The V-shaped openings, designed to be non-clogging, are narrowest at the outer face and widen inwardly.

Continuous-slot screens provide more intake area per unit area of screen surface than any other type.

For any given slot size, this type of screen has maximum open area.
